Antifungal indicated for fungal infections of the skin, scalp and nails.
Pharmacokinetics data (low oral bioavailability, high volume of distribution and high protein-binding capacity) explains the scanty excretion into breast milk observed.
In addition, its low oral bioavailability (Novartis 2018) would make even more difficult any pass of this drug through ingested milk to the infant's blood, except in newborns or premature who would show a higher intestinal absorption. (Thieme 1986 in Lactmed)
Avoid using in prematures who are under treatment with caffeine or theophylline because terbinafine alters its metabolic degradation and increases plasma concentration. (Novartis 2016, Mactal 2001)
Until more published data is known about this drug in relation to breastfeeding, known safer alternatives are preferable (LactMed, Hale, Butler 2014, Mactal 2001), especially during the neonatal period and in the event of prematurity.
TOPICAL ADMINISTRATION: Fully compatible with breastfeeding. (Leachman 2006)
Since topical absorption is less than 5 %, a significant excretion into breast milk after application on skin is not expected.
Do not use on the breast to prevent ingestion by the infant, otherwise apply after a feeding and wipe it out thoroughly with water before next feeding.
It is recommended to avoid using on the nipple creams, gels and other products intended for use on skin that may contain paraffin (mineral oil) in order to keep from absorption the infant. (Concin 2008, Noti 2003)
