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.
