Is penicillin v potassium-oral solids safe to take if I'm pregnant or breastfeeding?

Penicillin V potassium is classified as FDA pregnancy risk category B (Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women). Use of penicillin products in humans has not shown any evidence of fetal harm. Additionally, no evidence of fetal harm has been reported in animal studies. However, there is a lack of adequate and well controlled studies in pregnant women. As with all medications, use of penicillin V potassium during pregnancy requires careful evaluation of treatment benefits and potential risk to the fetus.

Penicillin V potassium is excreted in breast milk. Penicillin products have been reported to cause diarrhea, candidiasis (fungal infections), and skin rash in breast feed babies. Due to the lack of safety data, this medication should be used cautiously in females who are breastfeeding. Penicillin type antibiotics are used for treating infection in children.
