Is Simvastatin Safe During Pregnancy?

Simvastatin (Zocor®) is a pregnancy Category X medicine, meaning that it could potentially cause harm to your unborn child. Therefore, this drug is not recommended for women who are pregnant. If you are taking simvastatin and become pregnant, or if you are thinking of becoming pregnant, talk with your healthcare provider right away.

Simvastatin and Pregnancy Category X

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 X is given to medicines that show problems to the fetus in animal studies or in humans who have mistakenly taken the medicine. The use of a pregnancy Category X medicine during pregnancy is not recommended.

Final Thoughts

The effects of high cholesterol do not cause problems for many years or even decades. Therefore, if a woman does not take cholesterol medicine during pregnancy, it is not likely to have any impact on long-term risks. Since there is little benefit and a very real risk during pregnancy, your healthcare provider will recommend that you not take simvastatin while pregnant. If you are thinking of becoming pregnant, please make sure that you discuss the issue with your healthcare provider.
