Which medication is NOT recommended for hypertension in pregnancy?

In the management of hypertension during pregnancy, certain medications are preferred due to their safety profiles. Methyldopa, nifedipine, and labetalol are all considered safe and effective treatments for managing high blood pressure in pregnant individuals. These medications have been extensively studied and are recommended by various guidelines for their efficacy and safety for both the mother and the fetus.

On the other hand, phenylephrine is not recommended for treating hypertension in pregnancy. While it is an alpha-agonist that can raise blood pressure, its use in this context could lead to increased vascular resistance and a decrease in uteroplacental blood flow. This can potentially compromise fetal oxygenation and lead to adverse outcomes. Therefore, phenylephrine is generally avoided in the treatment of hypertension during pregnancy, making it the correct answer to this question.
