Topical antifungal effective in the treatment of superficial dermatophytosis (ringworm) and pityriasis versicolor.
Pediatric use authorized from 2 years.
1% topical application twice a day for 2 to 6 weeks.

At the date of the last update, the authors did not find any published data on its excretion in breast milk.

The small dose and poor plasma absorption of most topical dermatological preparations make it unlikely that a significant amount will pass into breast milk.
The absorption of tolfnaphtate in the dermis is less than 1 microgram/cm2 (Kezutyte 2010).

Do not apply on the breasts to prevent the infant from ingesting it; if necessary, apply after one feeding and clean well with water before the next.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
