Atorvastatin in Pregnancy — Is It Safe?
Last reviewed: · Source: US FDA drug label database
Stop statins when pregnant or trying to conceive — cholesterol is essential for fetal development, and pausing treatment for nine months is almost always safe for the mother.
Is it safe to take Atorvastatin with Pregnancy?
Atorvastatin and other statins are discontinued in pregnancy. Cholesterol is a building block for fetal cell membranes, hormones and brain development, so switching off its production is biologically the wrong direction during pregnancy. The FDA softened its labelling in 2021 — accidental early exposure hasn't shown the malformation pattern once feared, so there's no panic if you conceived on a statin — but the standing advice remains: stop on a positive test (ideally before conception) and restart after pregnancy and breastfeeding.
How do Atorvastatin and Pregnancy interact?
Statins inhibit HMG-CoA reductase, reducing cholesterol synthesis. The fetus requires cholesterol for membrane synthesis, steroidogenesis and sonic hedgehog signalling in development. Human data have not confirmed early teratogenicity signals, but interruption of a nine-month treatment window rarely harms maternal cardiovascular outcomes, so risk-benefit favours pausing.
Data sourced from the US Food and Drug Administration (FDA) drug label database: FDA 2021 statement — removal of blanket statin pregnancy contraindication, discontinuation still advised.
Who should be careful?
Women with familial hypercholesterolaemia or prior cardiovascular events need specialist input rather than a simple stop — some high-risk cases warrant individualised plans. Everyone else: stop and restart later.
What if I've already taken Atorvastatin and Pregnancy?
Took statins before realising you were pregnant? Stop now and tell your midwife — accidental early exposure has not shown a confirmed malformation pattern. High-risk cardiac history? Ask for specialist referral rather than simply stopping unmonitored.

Frequently Asked Questions
Do I stop atorvastatin when pregnant?
Yes — stop when you get a positive test (or before trying) and tell your GP. Treatment resumes after pregnancy and breastfeeding.
I took my statin for weeks before finding out — have I harmed the baby?
Reassuringly, accidental early statin exposure hasn't shown a confirmed pattern of birth defects. Stop now and inform your midwife.
What about my cholesterol during pregnancy?
Cholesterol naturally rises in pregnancy and a treatment pause of under a year rarely changes long-term risk. Diet and activity continue; high-risk cases get specialist review.
Can I take a statin while breastfeeding?
Statins are generally avoided during breastfeeding too. Restart once feeding finishes, guided by your GP.
