In a pregnant woman presenting with tremors and palpitations, which treatment is contraindicated?

In the context of treating hypertension or anxiety-related symptoms in a pregnant woman, atenolol is contraindicated due to concerns about fetal safety. Research indicates that atenolol has been associated with adverse outcomes in the fetus, particularly regarding growth restriction and potential effects on the newborn. Because of these risks, it is generally recommended to avoid using atenolol during pregnancy, especially in women who may require treatment for hypertension or related conditions.

Other beta-blockers, such as metoprolol and labetalol, are considered safer alternatives during pregnancy and are more commonly used when treatment is necessary. Propranolol, though less frequently preferred than metoprolol or labetalol, is also used under certain circumstances. The key takeaway is the importance of selecting medications that have established safety profiles in pregnancy, making atenolol an inappropriate choice in this scenario.
