Which antihypertensive is preferred during pregnancy, and why?

• A. ACE inhibitors are preferred in pregnancy because they are safe
• B. Labetalol (or hydralazine) is preferred; ACE inhibitors are teratogenic and contraindicated
• C. Methyldopa is the first-line
• D. Beta-blockers are contraindicated in pregnancy

Answer: (B)

In pregnancy, the safest approach to controlling hypertension is to use medications with well-established fetal safety. ACE inhibitors are avoided because they are teratogenic, especially after mid-pregnancy, and can cause fetal renal damage and other complications. Labetalol is favored because it effectively lowers blood pressure and has a strong safety profile for the fetus when used in pregnancy. Hydralazine is another option, often used for rapid control of severe hypertension or in hypertensive emergencies. While methyldopa has a long history of maternal safety, labetalol (and sometimes hydralazine acutely) is typically preferred as first-line in many guidelines. Beta-blockers are not universally contraindicated; labetalol itself is an example of a beta-blocker that is safely used in pregnancy, whereas the blanket statement that beta-blockers are contraindicated is not accurate.
