Which lipid-lowering agent is considered safe in pregnancy?

• A. Statins
• B. Bile acid sequestrants (cholestyramine)
• C. Niacin
• D. Fibrates

Answer: (B)

In pregnancy, safety of lipid-lowering therapy hinges on whether the drug crosses the placenta and its potential fetal risk. A non-absorbed bile acid sequestrant like cholestyramine stays in the gastrointestinal tract and does not enter the maternal circulation, so it does not reach the fetus. That makes it the best option among lipid-lowering agents when therapy is needed during pregnancy. Statins reduce cholesterol synthesis and have been associated with fetal harm in animal studies and observational data in humans, so they are avoided during pregnancy. Niacin and fibrates have limited safety data and potential fetal risks, so they are generally not used in pregnancy. Additionally, bile acid sequestrants can interfere with absorption of fat-soluble vitamins and other medications, so management includes monitoring and vitamin supplementation as needed.
