Is HSDB 8123 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use HSDB 8123? Is HSDB 8123 safe for nursing mother and child? Does HSDB 8123 extracts into breast milk? Does HSDB 8123 has any long term or short term side effects on infants? Can HSDB 8123 influence milk supply or can HSDB 8123 decrease milk supply in lactating mothers?

Antiviral agent used for topical treatment of herpes of the lip. Famciclovir is its precursor drug which is used for systemic treatment. At latest update, relevant published data on excretion into breast milk were not found. After topical use, plasma levels are undetectable. Such property is the main reason by which it is not excreted into breast milk, In addition, a low oral bioavailability would impede the absorption from ingested milk toward the infant's plasma. Do not apply creams, gels and other products for topical use that would contain paraffin (mineral oil) on the breast to prevent ingestion by the infant. If necessary, apply HSDB 8123 after a feed and clean thoroughly with water before the next.

Although there is no published experience with HSDB 8123 during breastfeeding, infant side effects are unlikely with maternal topical application to small areas of the mother's body away from the breast. Only water-miscible cream or gel products should be applied to the breast because ointments may expose the infant to high levels of mineral paraffins via licking.[1]
