Ancef and Pregnancy
When Ancef (cefazolin) was given to pregnant animals, it did not appear to cause any problems in the offspring. As a result, the drug is generally considered safe for use during pregnancy. However, animals may have a different response to drugs than humans, so it is important to talk to your healthcare provider about the benefits and risks of using Ancef during pregnancy.
Ancef® (cefazolin) is a prescription antibiotic given intravenously (by IV) or by intramuscular (IM) injection. It is usually considered safe for use during pregnancy.
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. Ancef is classified as a pregnancy Category B medication.
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. Medications that have been shown to be safe for use in pregnancy in humans but have caused problems in laboratory animals are also given a Category B rating.
Ancef was given a pregnancy Category B rating because studies in pregnant rats, rabbits, and mice did not appear to cause any problems. However, it is important to note that animals do not always respond to medicines in the same way that humans do. Therefore, a pregnancy Category B medicine, including Ancef, should be given to a pregnant woman only if her healthcare provider believes that the benefits to the woman outweigh any possible risks to her unborn child.
If you are pregnant or thinking of becoming pregnant while using Ancef, let your healthcare provider know. He or she will consider both the benefits and risks before making a recommendation in your particular situation.
