Taking Penciclovir While Breastfeeding
What are recommendations for lactation if you're taking Penciclovir?
Although there is no published experience with penciclovir 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]
