Pregnancy: Animal studies with ampicillin have shown no teratogenic effects. The product has been in extensive clinical use since 1961 and its use in human pregnancy has been well documented in clinical studies. When antibiotic therapy is required during pregnancy, ampicillin may be considered appropriate.
Lactation: During lactation, trace quantities of penicillins can be detected in breast milk.
Adequate human and animal data on use of ampicillin during lactation are not available.
