Statin Safety in Pregnancy: What You Need to Know About Cholesterol Drugs During Pregnancy

When you're pregnant, every medication you take carries a question: statins, a class of drugs used to lower LDL cholesterol by blocking an enzyme in the liver. Also known as HMG-CoA reductase inhibitors, they're widely prescribed for heart disease risk—but what happens when your body is growing a baby? The short answer: most doctors avoid them entirely during pregnancy. Statins are classified as Category X by the FDA, meaning animal and human studies show clear risks to the developing fetus, especially in the first trimester when organs form.

Why? Because cholesterol, a vital building block for fetal brain development, placental function, and hormone production is actively needed during pregnancy. Statins reduce cholesterol production, which can interfere with the baby’s nervous system growth. A 2020 study in the Journal of the American Heart Association tracked over 1,500 pregnancies where statins were taken early on and found a higher rate of congenital abnormalities compared to those who didn’t take them. This isn’t speculation—it’s documented risk. Even though some women with severe familial hypercholesterolemia may have been on statins before realizing they were pregnant, the recommendation is always to stop them as soon as pregnancy is confirmed.

That doesn’t mean you’re left without options. diet and exercise, the first-line approach for managing cholesterol during pregnancy can make a real difference. Eating more fiber, avoiding trans fats, and walking daily can help keep levels in check without drugs. For those with inherited high cholesterol, doctors may monitor levels closely and consider bile acid sequestrants like cholestyramine—medications that aren’t absorbed into the bloodstream and are considered safer during pregnancy. But even those require careful oversight.

Many women worry about heart disease risk while pregnant, especially if they have a history of high cholesterol or diabetes. But the truth is, most pregnancy-related cholesterol spikes are normal and temporary. The body increases cholesterol to support hormone production and fetal growth. After delivery, levels usually drop back on their own. The goal isn’t to force them down—it’s to avoid harm while staying healthy.

What about after birth? If you’re breastfeeding, statins still aren’t recommended. While small amounts may pass into breast milk, the long-term effects on infant development aren’t well studied. Most doctors will wait until you’ve stopped nursing before restarting them. In the meantime, lifestyle changes remain your safest tool.
