Amoxicillin and Pregnancy

In animal studies on amoxicillin and pregnancy, the medication did not cause any problems when it was given in large doses to pregnant rats and mice. Although the antibiotic has not been adequately studied in pregnant women, case reports suggest that amoxicillin does not increase the risk of birth defects or miscarriages. If you are taking amoxicillin and pregnancy occurs, let your healthcare provider know.

An Overview of Using Amoxicillin During Pregnancy

Amoxicillin (Amoxil®, Moxatag) is a prescription antibiotic. It is usually considered to be safe for use during pregnancy, although the full risks are not currently known.
 

Amoxicillin and Pregnancy Category B

The U.S. Food and Drug Administration (FDA) uses a pregnancy category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category B is given to medicines that have not been adequately studied in pregnant humans but do not appear to cause harm to the fetus in animal studies.
 
When large doses of amoxicillin were given to pregnant rats and mice, the medication did not cause any problems. Studies have shown that amoxicillin crosses the placenta (to the baby) in humans, but it does not appear to cause problems. Although amoxicillin has not been systematically and adequately studied in pregnant women, case reports and surveys seem to suggest that amoxicillin does not increase the risk of birth defects or miscarriages.
 
However, since amoxicillin has not been adequately studied in pregnant women, it is possible that it may have negative effects that are not currently known. Therefore, a pregnancy Category B medicine should be given to a pregnant woman only if a healthcare provider believes that the benefits to the pregnant woman outweigh any possible risks to the unborn child.
