Statins and Pregnancy
It can be dangerous to take statins when pregnant. Statin medication are classified as a pregnancy Category X medication, which means that statins have been shown to cause problems to the fetus in animal studies or in pregnant women who have mistakenly taken the medicine. Because of the risks associated with taking statins during pregnancy, women should not take the medication if they are pregnant or planning on becoming pregnant.
Are Statins Safe During Pregnancy?Statins are "contraindicated" during pregnancy. This means that pregnant women should not take them. If you are pregnant or thinking about becoming pregnant and take a statin medication, talk to your healthcare provider right away.
Statins and Pregnancy Category XThe 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 refers to medicines that caused problems to the fetus in animal studies or in humans who mistakenly took the medicine while pregnant. Also, medications for which the potential risks (even if they are merely theoretical) always outweigh benefits are given a Category X rating. The use of a Category X medicine during pregnancy is not recommended.
There have been occasional reports of problems (such as miscarriages or birth defects) possibly due to the use of statins in humans, but it does not appear that statin drugs actually increase the risks of such problems. After all, a certain number of miscarriages and birth defects will occur during pregnancies, even if no medications are taken.
Theoretically, statins could cause problems, as cholesterol is necessary for normal fetal development. Because statins provide no significant benefit during pregnancy and because there are theoretical risks, they are not recommended for use in pregnant women.
