Haemorrhoids (piles ) and Breastfeeding

The pain and discomfort of piles after birth can make breastfeeding difficult. You do not need to avoid the over the counter products which do not pass significantly into breastmilk

Haemorrhoids (piles) are common after birth, especially after an extended second stage of pushing. They can be incredibly painful or cause intense itching. They may also bleed. They can make breastfeeding difficult as it becomes too painful to sit for prolonged periods. They can also occur because of constipation due to taking strong opioid painkillers.

Symptoms according to the NHS https://www.nhs.uk/conditions/piles-haemorrhoids/

  • bright red blood after you poo
  • an itchy anus
  • feeling like you still need to poo after going to the toilet
  • mucus in your underwear or on toilet paper after wiping your bottom
  • lumps around your anus
  • pain around your anus

Simple measure that you can take include:

The over the counter remedies of creams, ointments and suppositories are all acceptable during breastfeeding despite what the manufacturer leaflet may suggest. Examples include Anusol™, Anusol HC ™, Preparation H ™, Germaloids™, Scheriproct™, Xyloproct™

Anusol has recently launched a product aimed at breastfeeding mothers but it is considerably more expensive, ” Anusol™ Natural Cream is a non-medicated formula that is safe to use during pregnancy and breastfeeding. “

What do mothers want professionals to know about contraception and breastfeeding

Last year I asked on my facebook page for experience of using contraception whilst breastfeeding using a googledoc survey. I had just under 80 responses in 24 hours and here I have tried to analyse the results. Five mothers reported that their supply was affected by the use of contraception. Many more were unhappy with the information that was given before prescription of the contraceptive. Food for thought

Please see https://www.breastfeedingnetwork.org.uk/contraception/ 

for information on the contraceptives and

on emergency hormonal contraception which I wrote for BfN.

Contraception and breastfeeding. What mothers want doctors to know analysis

A Googledoc survey was added to the facebook page Breastfeeding and Medication on 14.6.21. In the following 48 hours it received 78 responses from mothers reporting their experiences on their use of contraception whilst breastfeeding. It provides just a snapshot of a self-selecting group of women breastfeeding and using contraception. The numbers involved do not make it statistically significant and more work is needed. It may provide a template for hospitals who plan to initiate LARC prescription immediately after birth to use as an audit. It may also provide information for professionals who prescribe contraception as to what mothers want to discuss.

  1. Were you prescribed contraception after the birth of your baby?

12.8% of the mothers (10) had chosen not to use contraception, 1 had been unable to book an appointment due to non-availability of appointment during COVID, 1 was using LAM (Lactational amenorrhoea method), 18 were using condoms and one used the contraceptive patch, no one used the diaphragm. The most frequently cited method of contraception was not surprisingly the mini pill (37.2%).

Number of responses: 77 responses.

The age of the baby when contraception was initiated ranged from a few days to 25 months. Twenty-eight (36%) initiated contraception between 6 and 8 weeks, the time of the normal post-natal check.

Did you notice any effect on your baby or milk supply after beginning the contraception?

52 (66.7%) responses highlighted no effect on the baby or milk supply, 21 not applicable but 5 (6.4%) reported difficulties.

  • Depot Provera given 3 days Postpartum. Not sure as she was my first baby, but breastfeeding was a dream up until that point. Afterwards she kept coming off and never seemed satisfied. Perhaps one has nothing to do with other not sure. No idea if one influenced the other as was given no info on how the jag may affect my milk. Breastfeeding became a nightmare almost overnight and I was forced to give up feeding myself when my daughter was 3 weeks old.
  • Combined pill at 2 months Postpartum. Milk supply dropped from 10oz down to 4oz per pump. I stopped sooner than I planned. My doctor assured me it wouldn’t affect my feeding/supply. After my supply dropped, I researched and found I wasn’t the only one
  • Mini pill initiated at 8 weeks Postpartum. Decline noted but it could have been supply regulating. I continued to meet my babies needs and stopped when ready to do so.
  • Mini pill initiated at 7 weeks Postpartum. Given no information on compatibility with breastfeeding by the GP. I stopped contraception after one month so I could continue breastfeeding
  • Combined pill initiated after 25 months. Lost supply & toddler stopped breastfeeding. The prescription was initiated by a nurse and the mother was not happy with the information provided. She stopped sooner than she had planned

Were you happy with the information you were given before beginning contraception?

That only 27 out of 69 of the women prescribed contraception described as satisfied with the information provided is of concern. The vast majority of consultations were with GPs. It is acknowledged by most doctors that time available within consultations particularly at the post-natal check is pressurised.

Do you think that your contraception influenced how long you breastfed for?

Of the 78 responses 40 (51.3%) said that contraception had not affected how long they had breastfed. Three stated that they had stopped sooner than they planned. 18 (23.1%) responded that the question was not applicable whilst a further eleven comments (14%) were that they were still breastfeeding

Respondents were offered the opportunity to add open comments about contraception and breastfeeding.

  • I was pressured in to taking something at my check-up which I didn’t really need and badly affected my mood. Stopped taking after first prescription.
  • Yes. I felt I could not use it for fear of a reduction in milk production and changing my hormones (get bad pms so did not want to risk ill mental health because of contraception)
  • My doctor refused to give me a Mirena (I had one in before I conceived) because she said it wasn’t allowed until 9 months. I now know this is untrue but she wouldnt let me have one, so I have no choice but to wait. I didnt really want the mini pill but had no choice.
  • No. I’m still breastfeeding but stopped POP after a month as it was affecting my mood
  • Much more information should be given not just a leaflet
  • I think very little emphasis placed on breastfeeding; in mind of GP the only important thing is not getting pregnant again, not impact on breastfeeding
  • The mini pill caused me to bleed randomly which I didn’t realise until I reduced breastfeeding and my periods returned at around 12 months. I stopped it and used condoms
  • Still breastfeeding but stopped mini pill as I was bleeding constantly on it which I wasn’t warned about
  • I was not asked about breastfeeding when I requested mini pill.
  • Still BF at 16 months but I stopped taking the mini pill after 3 months
  • On my first appointment the GP actually refused to fit the coil as I told her that I’d been having unprotected sex with my husband, but due to lactational amenorrhea hadn’t had a period since before pregnancy. I told her I knew my body and that I absolutely was not pregnant. She made me do a pregnancy test (negative) and then told me to come back in 7 days, ensuring I used protection in the meantime.
  • Although the information I received from the GP prior to the appointment covered postnatal, it did not cover anything for breastfeeding women whose periods had not returned.
  • I had the coil which started my periods which is a massive downfall as had zero periods whilst breastfeeding without contraception
  • Had POP pill from 12weeks after 1st. Massive difference! I have horrible moods on pill, much less with implant. I believe the implant made me less stressed, less emotional, and better able to deal with the disrupted sleep etc. No impact on supply whatsoever.
  • I am a GP and I know that the COCP is licenced from 6weeks, but I am worried it would affect supply so didnt personally want to use it so early.
  • Recently needed the morning after pill.  I chose the Ella one pill. Had to lie on the online form to be able to purchase it and the in-box leaflet instructs breastfeeding mothers to pump for a week following taking the tablet and to dispose of the breast milk.
  • The Dr at the sexual health clinic tried convincing me that I didn’t need the implant, that breastfeeding alone was good enough. I am now on oestrogen cream/pessary as the combo of implant and breastfeeding meant I never healed properly due to my hormone levels and I had gynae issues e.g., soreness, dryness, scar was tender. The specialist would have preferred me to stop breastfeeding, but I wished to continue. Couldn’t change my implant to a pill as I get migraines.
  • My GP advised against coil placement until breastfeeding had ceased for 2 months
  • I use the Creighton Family Planning method and breastfed my first until he was 22 months. I got pregnant when he was 17 months. I knew when I was going to ovulate and chose to try then. Breastfeeding was a fantastic way for spacing out the two pregnancies.
  • I would like to have more information about how contraception can affect milk production and mood post birth
  • I felt very pressured by my GP to go on the pill at my 6-week appointment. She kept telling me that breastfeeding doesn’t stop you from falling pregnant, which I knew. I insisted that I did not want to go on anything as I had had a bad experience with contraception years ago.

Discussion

There are currently recommendations to initiate LARC (Long acting, reversible contraception) methods before women leave hospital after delivering their baby. This is to reduce the incidence of unwanted pregnancies and to provide a “one-stop” convenient place to receive contraceptive advice and prescription. This has become increasingly important during the COVID19 pandemic when it has been difficult to achieve [Immediate Postpartum Long-Acting Reversible Contraception https://www.acog.org/clinical/clinical-guidance/committee-opinion/articles/2016/08/immediate-postpartum-long-acting-reversible-contraception]. [FSRH CEU: Provision of contraception by maternity services after childbirth during the Covid-19 Pandemic April 2020 https://www.fsrh.org/standards-and-guidance/documents/fsrh-ceu-provision-of-contraception-by-maternity-services-after/][

In “ Guidance on the provision of contraception by maternity services after childbirth during the COVID-19 pandemic “https://www.rcog.org.uk/globalassets/documents/guidelines/2021-02-guidance-on-the-provision-of-contraception-by-maternity-services-after-childbirth-during-the-covid-19-pandemic.pdf] it states that:

POP: “Women can be reassured that it does not affect their breast milk supply. It can be started immediately after birth (or by day 21) without any requirement for additional contraceptive precautions”

Depot medroxyprogesterone acetate: “Depot medroxyprogesterone acetate (DMPA) can be administered immediately after childbirth and could be administered prior to discharge if other methods are unsuitable, unacceptable or unavailable. Women can be reassured that it does not affect their breast milk supply”

COC: “Combined hormonal contraception should not be started until 6 weeks after birth in breastfeeding women “

In Medications and Mother’s Milk Dr Thomas Hale states that:

Though the levonorgestrel data suggests minimal to no effect, we have received numerous reports at the InfantRisk centre of milk suppression following insertion of the levonorgestrel IUD.

The most sensitive time for changes in milk supply is early postpartum before lactation is established; therefore, waiting as long as possible (minimum 4 weeks) prior to use is advised. [ Queenan J. Exploring contraceptive options for breastfeeding mothers. Obstet Gynecol2012;119(1):1-2.] All mothers who take hormonal contraception should be counselled of possible effects on milk supply and monitored for such.”

Conclusion

There is currently little good research on the effect of contraception and breastfeeding. It is all too easy to dismiss a mother stating that her milk supply decreased, as one of the large proportion who couldn’t breastfeed. Breastfeeding practitioners across the UK and USA have raised concerns and advocated that breastfeeding women should receive full information of the compatibility with breastfeeding and possible effects on mood as well as supply so that they can be involved in shared decision making.

If women who notice a change in supply would complete a yellow card report that would assist in highlighting this as an issue. https://yellowcard.mhra.gov.uk/

If LARC prescriptions are issued by a maternity unit, an audit after 6-8 weeks on whether mothers are still breastfeeding would provide useful information.

In this very small, self-selecting study 4 women have reported that their breastfeeding was changed by the prescription of contraception, including one who was given a Depot medroxyprogesterone acetate 3 days after delivery, who was unable to breastfeed her baby at all after 3 weeks.

However, most importantly it has shown that many women have concerns about the information that they are provided with. This is surely a situation we should not be comfortable with.

Vaccines and Breastfeeding

this information is reproduced from my book Breastfeeding and Medication

pdf https://breastfeeding-and-medication.co.uk/wp-content/uploads/2024/06/vaccines.pdf

Vaccines have low bio-availability and absorption from breastmilk is unlikely in most circumstances other than with live vaccines. Cessation or interruption of breastfeeding is not normally required but individual regimens should be considered especially with yellow fever (Data taken from LactMed website [2012]; Martindale [2005]; Advisory Committee on Immunization Practices [ACIP]; CDC [Kroger 2006]; Advisory Committee on Immunization Practices [2006]). UK data are available in the Department of Health ‘The Green Book’ available on the internet (Plotkin and Orenstein 2004; Department of Health Green Book).

Although there is a theoretical risk of live vaccine being present in breastmilk, vaccination with common vaccines is not contra-indicated for women who are breastfeeding when there is significant risk of exposure to disease. There is no evidence of risk from vaccinating women who are breastfeeding, with inactivated viral or bacterial vaccines or toxoids (BNF).

               Measles, mumps and rubella     

Rubella vaccine virus can appear in breastmilk and result in infections in some infants (Buimovici-Klein et al. 1977). There is no evidence of mumps and measles vaccine viruses being found in breastmilk. Some breastfed infants acquire passive immunity to rubella after maternal vaccination, as do infants of mothers with natural rubella immunity. However, neither group of infants has a decreased response to rubella vaccine administered directly (Krogh et al. 1989). The CDC (Kroger et al. 2006) state that vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants and that breastfeeding is not a contra-indication to MMR vaccine. Breastfed infants should be vaccinated according to the routine recommended schedules (Plotkin and Orenstein, 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

Diptheria, tetanus and pertussis             

One study of previously vaccinated infants found that at 21 to 40 months of age breastfed infants had higher immunoglobulin G (IgG) levels against diphtheria, higher secretory IgA levels in saliva against diphtheria and tetanus and higher fecal IgM against tetanus than formula-fed infants (Hahn-Zoric et al. 1990).

Pisicane et al. (2010) found that breastfed infants were also less likely to have fever after immunisation than their non-breastfed counterparts. Lopez-Alarcon et al. (2002) found they were also less likely to experience loss of appetite and reduced energy intake after routine childhood immunisation than those who are not breastfed. Although baseline calorie intakes were higher in the formula-fed infants mean intakes fell by 12% in the post-immunisation period.

There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

               Meningococcal vaccination         

Immunisation of pregnant or lactating women with meningococcal vaccine increased the specific secretory IgA content of milk ( Shahid et al. 2002). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated virus or bacterial vaccines or toxoids (Granoff et al. 2004, Department of Health Green Book).

Typhoid vaccination        ☺

Recommended as compatible with breastfeeding by the CDC and the American Academy of Pediatrics (AAP).

Influenza vaccination    

Use of live, attenuated or inactivated vaccine is recommended as compatible with breastfeeding by the CDC and the AAP. There is no evidence of risk from vaccinating pregnant women, or those who are feeding, with inactivated viral or bacterial vaccines or toxoids (Plotkin and Orenstein 2004). Where possible, pregnant women should receive a thiomersal-free influenza vaccine (Department of Health Green Book ).

BCG vaccination             

BCG vaccination against tuberculosis is recommended as compatible with breastfeeding by CDC and the AAP (Kroger 2006). Although no harmful effects on the foetus have been observed from BCG during pregnancy, it is wise to avoid vaccination, particularly in the first trimester, and wherever possible to delay until after delivery. Breastfeeding is not a contraindication to BCG (Plotkin and Orenstein 2004; Department of Health Green Book).

Pneumococcal vaccines

Some evidence of decreased pneumococcal disease has been found among breastfed infants of vaccinated mothers (Lehmann et al. 2003). Pneumococcal-containing vaccines may be given to pregnant women when the need for protection is required without delay. There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book).

Varicella vaccine            

Recommended as compatible with breastfeeding by the CDC and the AAP (Kroger 2006). Women who are pregnant should not receive varicella vaccine and pregnancy should be avoided for 3 months following the last dose. Studies have shown that the vaccine virus is not transferred to the infant through breastmilk (Bohlke et al. 2003) and therefore breastfeeding women can be vaccinated if indicated (Plotkin and Orenstein 2004; Department of Health Green Book ).

Compatible with use during breastfeeding.

Yellow fever vaccine     

Until 2009 no adverse effects to yellow fever vaccine had been reported in infants exposed via breastfeeding. In 2009, the first case of meningoencephalitis caused by the yellow fever vaccine virus transmitted via breastmilk was confirmed.

Traiber et al. reported on a 38-day-old infant who was exclusively breastfed by a mother who had received yellow fever vaccination, the baby was discharged when convulsions resolved.

Kuhn et al. reported a case study of a previously healthy 5-week-old baby admitted to hospital with a 2-day history of fever and irritability, he subsequently fitted in the emergency department. When the baby was 10 days of age his mother was given travel vaccinations including yellow fever for a holiday to Venezuela. Hospital tests showed symptoms consistent with encephalitis. His symptoms resolved following a 21-day course of aciclovir.

The CDC (Kroger 2006) recommend against vaccinating nursing mothers with yellow fever vaccine before the baby is 6 months of age. However, if travel by the nursing mother to a high-risk yellow fever endemic area cannot be avoided or postponed, the mother may be vaccinated. Exposure to yellow fever vaccine via breastmilk would not increase the risk to an infant who receives the vaccination after the age of 6 months (Plotkin and Orenstein 2004, Department of Health Green Book ).

Compatible with use during breastfeeding. Avoid in first 6 months unless essential.

Hepatitis B vaccine        

Recommended as compatible with breastfeeding by the CDC and the AAP (Kroger 2006). Breastfed infants of hepatitis B surface antigen positive mothers have a different response in the development of Ig subtypes after vaccination with hepatitis B vaccine than do formula-fed infants. However, breastfeeding does not interfere with the infant’s antibody response to hepatitis B vaccine (Azarri et al. 1990; Wang et al. 2003). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Plotkin and Orenstein 2004; Department of Health Green Book ).

Compatible with use during breastfeeding.

Cholera vaccine

Use of oral cholera vaccine to the mother decreased the risk of cholera in their breastfed infants by 47% in one study (Clemens et al. 1990). The authors hypothesised that vaccination of the mothers reduced their transmission of cholera to their infants. There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book ).

Polio vaccine    

Two types of poliomyelitis vaccine are available: inactivated poliomyelitis vaccine (for injection in combination with diphtheria vaccine) and live (oral) poliomyelitis vaccine.

Administration of oral poliovirus vaccine to nursing infants is less effective if it is given the neonatal period, due to maternal antibodies in colostrum and breastmilk (WHO 1995; Zaman et al. 1991). However, breastfeeding does not interfere with the infant’s response to oral polio vaccine, when given at the normal scheduled times (Kim-Farley et al. 1982; John et al. 1976). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids according to the CDC and the AAP (Kroger et al. 2006) and the Department of Health Green Book (Plotkin and Orenstein 2004; Department of Health Green Book  )

Compatible with use during breastfeeding.

Gallstones and Breastfeeding

The development of anaesthetic data was prompted at least in part by the questions from mothers are diagnosis, treatment and surgery for gallstones whilst pregnant. Women are more likely than men to have gallstones and they are more common after the birth of several children so unsurprisingly this frequently covers breastfeeding mothers.

So here are my thoughts and a fact sheet on the topic

gallstones and breastfeeding fact sheet

Gallstones are present in at least 10% of the population. They vary in size and shape and consist primarily of cholesterol or the bile pigment bilirubin. They occur twice as frequently in women as men. Risk factors include high cholesterol intake, obesity, having had several children and the use of oral contraceptives (Gould 2006).

Symptoms of gallstones

Gallstones frequently cause no symptoms but larger calculi (stones) can obstruct a duct causing sudden severe waves of pain in the upper right-hand side of the abdomen (just under the ribs) often radiating to the back and right shoulder.  Feeling sick or vomiting, with a high temperature, shivering and sweating are also common.

Severe pain (biliary colic) may be precipitated by eating a fatty meal. Chronic symptoms may include intolerance to fatty foods, belching, bloating and mild epigastric pain.

Treatment is usually necessary if gallstones are causing symptoms – such as abdominal pain or complications – such as jaundice or acute pancreatitis

In these cases, keyhole surgery to remove the gallbladder may be recommended. This procedure, known as a laparoscopic cholecystectomy, is relatively simple to perform and has a low risk of complications. It is possible to lead a perfectly normal life without a gallbladder. The liver will still produce bile to digest food, but the bile will just drip continuously into the small intestine, rather than build up in the gallbladder (NHS www.nhs.uk/conditions/gallstones/#treating-gallstones)

Diagnosis of gallstones

Apart from acute symptoms often requiring emergency admission, diagnosis is by Ultrasound, MRI and CT scans all of which can be undertaken without interruption to breastfeeding together with blood tests. https://breastfeeding-and-medication.co.uk/fact-sheet/breastfeeding-after-ct-and-mri-scans

Treatment of gallstone

Simple over the counter painkillers (paracetamol and ibuprofen) may be sufficient. Anti spasmodic drugs may also be prescribed e.g. Hyoscine (Buscopan®). Anti nauseants e.g. cyclizine or ondansetron may be required. All can be used with continued breastfeeding (Jones 2018)

Ursodeoxycholic acid has been used for the management of gallstone disease, there is no evidence to support its use.

Surgery for gallstones

A laparoscopic cholecystectomy involves only small cuts in the abdomen to pass the instruments. It is normally carried out as a day case enabling return home on the same day or at most after an overnight stay. Full recovery takes around 10 days and mothers may need help with lifting and caring for toddlers.

It is possible to breastfeed as soon as the mother is awake and alert after surgery as the drugs stay in the system a short time. Doses of antibiotics and painkillers may be administered in theatre or in recovery, but these would normally be suitable for breastfeeding.

Analgesia (pain relief) after surgery for gallstones

Response to pain after surgery is very individual. The use of paracetamol plus non- steroidal drugs such as ibuprofen, naproxen and diclofenac may be sufficient for some. Others may need opiate drugs. Oramorph and dihydrocodeine are the preferred drugs during breastfeeding. Codeine should not be prescribed https://breastfeeding-and-medication.co.uk/fact-sheet/pain-relief-when-breastfeeding

It is not acceptable to prescribe a drug which is unsuitable to be taken by breastfeeding mother as there are risks to not continuing normal breastfeeding (risk of engorgement or mastitis, risk baby will not take milk from a bottle, risk of allergy on exposure to artificial formula) but above all prescription should be in accordance with the stated wishes of the mother to continue to feed as normal.

Thrush and Breastfeeding

So many contacts recently about thrush and breastfeeding I have decided to record a presentation I have made many times over the years. I will in a few days record one with detailed prescribing information for doctors and pharmacists . A copy of the slides will go onto my website www.breastfeeding-and-medication.co.uk. Hope this helps everyone. I have found it necessary to leave several social media groups for my own sanity after reading threads where non evidence based practice seems to get perpetuated. This is my view after looking at thrush and breastfeeding for the last 20 years.

Medicalising Sore Nipples – thrush and breastfeeding July 2018

The origin of the BfN Breastfeeding and Thrush leaflet and factsheet

It feels a very long time since I recorded this video and it is now 25 years since Dr Magda Sachs and I wrote the first BfN leaflet about Thrush in Breastfeeding. At that time, as experienced breastfeeding supporters, we had seen maybe 6 mothers between us whose nipple pain had not been resolved by attention to positioning and attachment after months of breastfeeding without problem. We researched and found research about thrush and breastfeeding which exactly described what we were seeing. Those original references included :

Brent N., Thrush in the Breastfeeding Dyad: Results of a survey on diagnosis and treatment, Clin Paed. 2001; 40:503506.

Francis-Morrell J, Heinig MJ et al, Diagnostic value of signs and symptoms of mammary candidosis among lactating women. JHL 2004; 20:288-95 ›

Kaufman D, et al., Fluconazole prophylaxis against fungal colonisation and infection in preterm infants, N Eng J Med 2001; 345(23):1660-6.

Morrill JF et al. Risk factors for mammary candidosis among lactating women. J.Obstet.Gynecol. Neon.Nurse. 2005;34:37-45

We wrote the leaflet and then watched what became an avalanche of queries, recommendation and self diagnoses. Women repeated back to us the words such as “shark’s teeth” that we had used and we noted how hard they were trying to obtain treatment. We updated the leaflet a few years later and then wrote a factsheet as finances didnt allow further printing of leaflets.

Current research

There remains little research on thrush as a cause of nipple pain although it remains in the ABM Clinical Protocol #26: Persistent Pain with Breastfeeding https://abm.memberclicks.net/assets/DOCUMENTS/PROTOCOLS/26-persistent-pain-protocol-english.pdf

Do I still believe thrush affects breastfeeding women and causing nipple pain? Yes but in a small minority of cases. I think that most pain still comes from not quite positioning and attachment in the early days and often around 6 weeks when babies feed frequently and we assume that the latch is ok. I see another rush of instances of pain often described as thrush when babies are teething and again I think in most cases the latch has altered fractionally to take the pain off sore gums.

Miconazole oral gel

I do believe that miconazole gel is much more effective than nystatin drops and that is supported by research.

In 2008 Janssen-Cilag the manufacturers of Daktarin oral gel ® altered the licensed application of the product with respect to the age from which it is recommended. They recommend that it is not licensed for use in babies under 4 months of age and only with care between 4 and 6 months (EMC). I co-authored a paper published in the BMJ about this. https://www.bmj.com/content/338/bmj.a3178.long

This change appears to originate from a published report (De Vries 1996) documenting a 17 day old baby (born at 36 weeks gestation) who choked when exposed to miconazole oral gel applied to her mother’s nipples before and after feeds on the advice of a pharmacist. The baby suddenly stopped feeding and breathing, became cyanotic and lost consciousness. The mother scooped out the visible miconazole gel and the baby recovered within a few moments. The doctor who was called could find no abnormalities and the baby recovered without further problem. The report mentions nine other cases of babies who suffered some form of difficulty with breathing, one of who was admitted to hospital, but all recovered spontaneously.

The current research evidence for nystatin is poor according to Hoppe (1996, 1997).

If practitioners choose to continue to recommend miconazole oral gel they should ensure that the mother/carer is aware that the gel should be applied gently, in small amounts at a time until all the surfaces of the mouth are covered. It is important that a spoon is not used to administer the gel and that the back of the throat is not touched either by the adult’s finger or by the gel (Ainsworth 2009). Healthcare providers must ensure that when recommending this product that the parent/carer is aware of how to apply the gel safely i.e. using a clean finger, apply small amounts of gel at a time, four times a day after feeds. Practitioners who recommend miconazole oral gel that responsibility in a baby under 4 months lies with the person who prescribes or recommends its use. The licensed application does not necessarily imply a risk if used appropriately but each prescription should be considered on an individual basis. Under no circumstances should miconazole oral gel be applied to the mother’s nipples as a means of treating the baby or the mother.

Clotrimazole cream applied to the nipples

The lack of efficacy of clotrimazole cream applied to the nipples is anecdotal after supporting many women. The risk of it causing irritation comes from data supplied personally by Chloe Fisher and Sally Inch at the once famous breastfeeding clinic in Cambridge. Miconazole cream remains preferable in my opinion

The future?

I continue to believe that thrush affecting the breastfeeding dyad is rare and should only be used after all other reasons have been excluded or in the presence of positive swabs.

I refer you to another paper which I was involved in writing. “Identifying the cause of breast and nipple pain during lactation” https://breastfeeding-and-medication.co.uk/wp-content/uploads/2024/06/bmj.n1628.full-.pdf

Vaginal Thrush and Breastfeeding

Pdf https://breastfeeding-and-medication.co.uk/wp-content/uploads/2024/06/vaginal-thrush-and-bf.pdf

Most women have suffered the intense itching associated with vaginal thrush. It can also cause a white vaginal discharge (often described as like cottage cheese), which does not usually smell. It can also sting when you pass urine or have sex. It is a fungal infection but can occur after antibiotics, during hot weather or after wearing tight jeans regularly. It can also be caught from your partner during intercourse particularly if this has been maybe rapid or over enthusiastic. As an undergraduate I had this described as “honeymoon disease” but that was maybe in a different era!

It is not harmful but can be very uncomfortable. Some people experience symptoms more frequently than others.

Treatment:

Many treatments can be purchased over the counter rather than needing a GP appointment. The leaflets may say “ ask your GP or pharmacist if you are breastfeeding” which relates to licensing application rather than risk

  • Vaginal creams and pessaries containing clotrimazole (Canesten™)
  • External creams eg clotrimazole (Canesten™), Vagisil™
  • Single dose antifungal medication containing fluconazole (Canesten Once™, Diflucan™, Own brands
  • Combinations of internal and external creams, oral tablet and cream

Your partner can be treated with clotrimazole cream applied to the penis and extra lubrication during sex may help.

One natural remedy often recommended is to apply live, natural yoghurt on a tampon to restore natural flora and to eat live yoghurt/ take probiotics. Cotton pants, loose clothing and even going commando helps. Do not try to be over enthusiastic about wiping after going to the loo and try not to scratch as this will further damage the skin. Symptoms should resolve within a week

Asthma and Breastfeeding

As a community pharmacist I often saw patients repeatedly ordering their blue inhalers to relieve symptoms of asthma because they were scared that the brown preventer inhalers contained steroid and would make them look like body builders. This is, of course not going to happen using inhalers correctly. Oral thrush can be common if inhaler technique is poor but simple things like rinsing the mouth after use or using a spacer can help. Talk to your specialist asthma nurse if you are struggling with symptoms.

If we add in breastfeeding it is no surprise that mothers are concerned about their medication use to control asthma but without cause. Inhalers and steroids are compatible with breastfeeding. Not only that but breastfeeding helps to minimise the risk of your baby developing asthma in the future according to new research.

The symptoms of asthma being high because of very high pollen counts coupled with the risk of thunderstorms which can be a bad combination.

I hope this factsheet taken largely from Breastfeeding and Chronic Medical Conditions helps

wendy@breastfeeding-and-medication.co.uk

“My asthma actually improves when feeding and I had a big decline when I weaned my 2-year-old twins. The symptoms have gone again now I’m breastfeeding my 3-month-old.”

Description

Breastfeeding protects against asthma in children up to the age of 6. Shorter duration and non-exclusivity of breastfeeding were associated with increased risks of asthma-related symptoms in pre-school children (Mukherjee 2016). Thus, mothers with asthma may be keen to breastfeed exclusively to protect their baby. In a study of 366 pregnancies, symptoms worsened in 36% of women (Schatz 1988).  Further studies by Schatz (1995) and Wendel (1996) in the United States suggest that 11–18% of pregnant women with asthma will have at least one emergency department visit for acute asthma and, of these, 62% will require hospitalisation.

Wilson et al (2022) studied 2021 mother-child dyads. Women reported the duration of any and exclusive breastfeeding and child asthma outcomes during follow-up at child aged 4 to 6 years. Outcomes included current wheeze (previous 12 months), ever asthma, current asthma (having ≥2 of current wheeze, ever asthma, medication use in past 12-24 months), and strict current asthma (ever asthma with either or both current wheeze and medication use in past 12-24 months). They showed that longer duration of exclusive breastfeeding had a protective association with child asthma.

Treatment

Asthma can be controlled during breastfeeding with:

  • inhalers (short and long-acting beta 2 agonists to relieve symptoms
  •  bronchodilators to prevent symptoms
  • compound inhalers, 
  • Prednisolone
  • Leukotriene receptor antagonists. 

Beta-adrenoreceptor agonists relieve symptoms of asthma attack such as breathlessness: E.g., Salbutamol, Bambuterol , Formoterol, Salmeterol, Terbutaline.The inhalers act locally in the lungs and limited transfer into blood let alone milk –

Oral Corticosteroids : Prednisolone – limited transfer at 40mg/day, higher doses short term. Very high doses or long term wait 4 hours after administration to breastfeed (but rarely necessary in my experience)

Inhaled Corticosteroid Inhalers prevent asthma symptoms and are used when regular use of preventer inhalers is necessary: E.g., Beclometasone, Budesonide, Fluticasone, Mometasone. Inhalers  act locally in lungs and limited transfer into blood let alone milk

Leukotrine Receptor antagonists: Montelukast – relative infant dose 0.68%. Used in children so compatible with breastfeeding. However, in September 2019 the MHRA added a caution to use in children so individual mothers may need to decide for themselves if they wish to take this drug whilst breastfeeding.

“Healthcare professionals are advised to be alert for neuropsychiatric reactions, including speech impairment and obsessive-compulsive symptoms, in adults, adolescents, and children taking montelukast. The risks and benefits of continuing treatment should be evaluated if these reactions occur. Patients should be advised to read the list of neuropsychiatric reactions in the information leaflet and seek immediate medical attention if they occur.”

Theophylline/ Aminophylline – prolonged half-life in neonates (babies < 6 weeks). One reported case of irritability. Avoid if possible, especially with young babies .

There are many options of inhalers and asthma specialist should be able to make symptoms changing life a rare rather than common event. Many athletes have asthma and are able to control symptoms with the right balance of medication. For some symptoms are worse with respiratory infections, for others season affects are greater e.g., moulds, pollen from different plant affecting different times of the year.

The menopause and breastfeeding

I’m seeing increasing numbers of questions form mums in the perimenopause who are still breastfeeding. Maybe they delivered later or maybe they have been feeding to term or maybe lots of other reasons. I remember asking for blood tests to check my hormone levels because I just couldnt think clearly anymore and my memory was poor which wasnt ideal as I was just becoming an independent pharmacist prescriber! My levels had indeed dropped and I went on to HRT. This may not be everyone’s choice or be suitable for them

I have spent many hours this year looking for guidance on HRT and breastfeeding and failed to find any studies or conclusive data. Everything is anecdotal at the moment but I hope this information helps.

One vital piece of information – please keep checking your breasts for lumps .HRT can slightly increase the risk of breast cancer. If you’ve had breast cancer you’ll usually be advised not to take HRT. The increased risk is low: there are around 5 extra cases of breast cancer in every 1,000 women who take combined HRT for 5 years. The risk increases the longer you take it, and the older you are.

Risk of breast cancer BNF June 2024 https://bnf.nice.org.uk/treatment-summaries/sex-hormones/

All types of systemic (oral or transdermal) HRT treatment increase the risk of breast cancer after 1 year of use. This risk is higher for combined oestrogen-progestogen HRT (particularly for continuous HRT preparations where both oestrogen and progestogen are taken throughout each month) than for oestrogen-only HRT, but is irrespective of the type of oestrogen or progestogen. Longer duration of HRT use (but not the age at which HRT is started) further increases risk.

Although the risk of breast cancer is lower after stopping HRT than it is during current use, the excess risk persists for more than 10 years after stopping compared with women who have never used HRT. Vaginal preparations containing low doses of oestrogen to treat local symptoms are not thought to be associated with an effect on breast cancer risk.

The MHRA advises discussing the updated information on the risk of breast cancer with women who use or are considering starting HRT, at their next routine appointment. 

There are also risks of endometrial cancer, ovarian cancer, thromboembolism, stroke and coronary vascular disease.

As usual please message me on wendy@breastfeeding-and-medication.co.uk if you have a question

PDF of factsheet available:

https://breastfeeding-and-medication.co.uk/wp-content/uploads/2023/07/the-menopause-and-breastfeeding.pdf

The Menopause And Breastfeeding

There remains no conclusive research on the passage of HRT medication into breastmilk. It appears anecdotally that there is less impact on milk supply from using transdermal preparations than oral medication. There remains the possibility of reduction in lactation due to the oestrogen contact inhibiting prolactin. Anecdotally HRT at standard dose of less than 2mg has been used by breastfeeding women without impact on the nursling or supply. There is no research on higher doses or use outside of licence application.

For use of vaginal oestrogen see https://breastfeeding-and-medication.co.uk/fact-sheet/breastfeeding-and-oestrogen-cream-or-pessary

I typed “menopause and breastfeeding” into a well-known search engine and what came up first was “It is most likely that you are suffering from menopausal-like symptoms due to breastfeeding. After childbirth and during breastfeeding, women’s oestrogen levels can drop to lower levels than usual. These low levels of oestrogen can cause symptoms that mimic menopause.”

Whilst in a paper published in 2020 Langton et al found that after studying 100,000 women ages 25 to 42 years in the Nurses’ Health Study II (an analysis funded by the National Institutes of Health) “Women who breastfed their infants exclusively for seven to 12 months may have a significantly lower risk of early menopause than their peers who breastfed their infants for less than a month”.  The study also suggests that pregnancy can reduce the risk of early menopause.”

As many women now give birth later than in the past, due to changes in work and finance, and feed until they and their nursling choose to stop, questions that I have received from mothers exhibiting signs of early menopause have increased substantially. Most women begin the menopause between 45 and 55 years of age.

There is also a group who have experienced premature ovarian failure which may be hereditary. There is a further group who have had their uterus and ovaries removed surgically for a variety of reasons.

Premature ovarian insufficiency (POI)

This affects about one in a hundred women under 40 in the UK. It occurs when the ovaries no longer produce normal amounts of estrogen and therefore may not produce eggs. This means that periods will become irregular or stop altogether, with symptoms of the menopause. Many women have POI without actually realising it. Any mother under the age of 40 and having irregular periods (or if they have even stopped completely) should be talk to their doctor about having further tests. No woman is too young to be menopausal. Unlike the normal menopause when the ovaries stop working completely, in POI ovarian function can be intermittent, occasionally resulting in a period, ovulation or even pregnancy. This intermittent return of ovarian function means that 5–10% of women with POI will conceive spontaneously.

Perimenopause

The period leading up to the menopause, when hormone production decreases symptoms may start to be experienced is defined as the perimenopause. The period is rather ill defined and may vary dramatically between women. It usually suggested as beginning with irregular menstruation. There may be changes to flow with periods becoming heavier or lighter. For others it may be defined by mood swings or changes in mental function. Each person has a different awareness of their own bodies. This is the period in which most calls about breastfeeding appear to originate with a request to begin hormone replacement therapy.

Menopause

The menopause is defined as an absence of menstruation for over a year. Not all symptoms will be experienced by all women, we are all different.

Typical menopausal symptoms, include:

  • hot flushes
  • night sweats
  • vaginal dryness and discomfort during sex
  • difficulty sleeping
  • low mood or anxiety
  • reduced sex drive (libido)
  • problems with memory and concentration

However, Newson diagram shows that the menopause may affect any part of the body with a wide variety of symptoms

Reproduced from Newson, Menopause: All you need to know in one concise manual

Interestingly when Newson surveyed approximately 2,920 women about their experiences of care around the menopause. The majority of respondents had visited their usual GP:

  • 66% said they were offered antidepressants rather than HRT
  • 20% said they had been referred to a hospital for appointments and/or investigations e.g., migraine clinics, scans or heart tests with symptoms likely to be related to their perimenopause/menopause.

This suggests that medical understanding of perimenopausal symptoms may be poorly understood and probably more so if the women is breastfeeding as well, particularly outside of the perceived “normal” timeframe.

Post menopause

This is defined as the remainder of a women’s life which can present with an increased risk of osteoporosis although the risk is lowered in women who have breastfed (https://www.unicef.org.uk/babyfriendly/news-and-research/baby-friendly-research/maternal-health-research/maternal-health-research-bone-density/).

HRT and Breastfeeding

HRT contains oestrogen and sometimes a progesterone e.g., norethisterone, not that dissimilar to that in the combined oral contraceptive which can be used in breastfeeding. The ethinylestradiol content of COCs range from 20–40 micrograms whilst that in HRT products contain 1 – 2 milligrams of estradiol (there are 1000 micrograms in a milligram).

However, Hale says “Although small amounts of Conjugated estrogens may pass into breastmilk, the effects of estrogens on the infant appear minimal. Early postpartum use of estrogens may reduce volume of milk produced and the protein content, but it is variable and depends on dose and the individual.”

“Conjugated estrogens comprise more than 90% of the total estrogen content of human milk and plasma (McGarrigle) Estriol glucosiduronates were the predominant oestrogen metabolites (63%) in plasma”

His conclusion is that low levels pass into milk confirmed in a query to the InfantRisk forum (https://www.infantrisk.com/forum/forum/medications-and-breastfeeding-mothers/medications-and-mothers-milk/339-hormone-replacement-therapy )

Martindale (39th Ed) states that estradiol has been detected in breastmilk after the use of pessaries containing estradiol 50 or 100mg (Nilsson 1978) and that the American Academy of Pediatrics (2001) considers that it is compatible with breastfeeding
