Answer by Dr. Ru: About Famciclovir usage in lactation

Precursor of Penciclovir which is used for treatment of infections due to Herpes zoster and Herpes simplex viruses. At latest update, relevant published data on excretion into breast milk were not found. Possibly, a low risk medication during breastfeeding, since similar pharmacokinetics and side-effects are shared with well known drugs pertaining to the same family. Until more data on this medication is available, safer alternative drugs are preferred, especially in such critical age periods.

Because there is no published experience with famciclovir during breastfeeding, other agents may be preferred, especially while nursing a newborn or preterm infant.
