Coreg and Pregnancy
Studies with pregnant animals have been conducted on Coreg, and pregnancy problems appeared to be a possible risk. As a result, Coreg is considered a pregnancy Category C medicine, which means it should only be given to a pregnant woman if the benefits to her outweigh the risks to the fetus. If a woman becomes pregnant while taking this drug, side effects may be temporary or permanent.
Whether or not your healthcare provider recommends Coreg® (carvedilol) while you are pregnant will depend on your particular situation. There may be an increased risk to the fetus if Coreg is used during pregnancy. Your healthcare provider will consider the risk the drug presents, the risk of not treating your condition, and alternative treatment options before making his or her recommendation.
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 studied in pregnant humans but that do appear to cause harm to the fetus in animal studies. Also, medicines that have not been studied in any pregnant women or animals are automatically given a pregnancy Category C rating.
A pregnancy Category C medicine may still be given to a pregnant woman if the healthcare provider believes that the benefits to the mother outweigh the risks to the unborn child. For example, untreated high blood pressure during pregnancy carries its own set of significant risks to both the mother and the fetus (see Preeclampsia). In situations like this, a healthcare provider may prescribe a pregnancy Category C drug if the benefit of treating high blood pressure in pregnancy outweighs the risk the medicine presents.
