Benzamycin and Pregnancy

Due to potential fetal risks, Benzamycin (erythromycin/benzoyl peroxide) is classified as a pregnancy Category C medicine. This means that it may not be safe for use in women who are expecting. Although one of the active ingredients in this drug is considered safe for use during pregnancy, the other active ingredient has not been studied in any pregnant women or animals.

Can Pregnant Women Use Benzamycin?

Benzamycin® (erythromycin/benzoyl peroxide) is a prescription medication licensed to treat acne. It comes in the form of a gel that is applied to the skin. Based on information from animal studies, this drug does not appear to be particularly dangerous during pregnancy, although not all of the possible risks are known at this time.
 

What Is Pregnancy Category C?

Benzamycin is classified as a pregnancy Category C drug. The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category C is given to medicines that have not been adequately studied in pregnant humans, but have caused fetal harm in animal studies.
 
In addition, medicines that have not been studied in any pregnant women or animals are automatically given a pregnancy Category C rating.
 
When given to pregnant rats, erythromycin (one of the active ingredients of Benzamycin) did not appear to increase the risk for birth defects, miscarriages, or other problems in the fetus. Erythromycin itself (when used alone) is considered a pregnancy Category B medicine. Pregnancy Category B is given to medicines that have not been adequately studied in pregnant humans, but did not appear to cause fetal harm in animal studies.
 
However, neither Benzamycin nor benzoyl peroxide (the other active ingredient in Benzamycin) has been studied in pregnant animals or pregnant women. Even though only a small amount of Benzamycin is expected to be absorbed through the skin with normal use, all potential risks to an unborn child cannot yet be ruled out.
 
It should be noted, however, that animals do not always respond to medicines in the same way that humans do. Therefore, pregnancy Category C medicines, including Benzamycin, may be prescribed if a woman's healthcare provider believes that the benefits of the medication outweigh any possible risks to her unborn child.
 
The use of Benzamycin to treat acne during pregnancy may not outweigh the possibility of these risks. If you desire acne treatment during pregnancy, ask your healthcare provider for suggestions on safe and effective acne treatment strategies for pregnant women.
