Methyldopa — Uses, Dosage, Side Effects & Safety

Drug class: Antihypertensive (Centrally Acting Alpha-2 Adrenergic Agonist)

Overview

Methyldopa is a prescription medication used to treat high blood pressure (hypertension) in adults and children. It is especially well-known for its safety profile in pregnancy and is often recommended for managing hypertension during pregnancy. Methyldopa works by acting on the central nervous system to relax blood vessels, making it easier for the heart to pump and lowering blood pressure. By reducing blood pressure, methyldopa helps prevent strokes, heart attacks, and kidney problems. Key points for patients: Methyldopa may take a few days to reach its full effect. It is important to take it exactly as prescribed, even if you feel well, as high blood pressure often has no symptoms. Do not stop taking methyldopa suddenly without consulting your healthcare provider.
