Methyldopa is used to treat high blood pressure. Methyldopa is in a class of medications called antihypertensives. It works by relaxing the blood vessels so that blood can flow more easily through the body.
Methyldopa comes as a tablet and a liquid to take by mouth. It usually is taken two to four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take methyldopa exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Shake the liquid well before each dose to mix the medication evenly. Use a dose-measuring spoon or cup to measure the correct amount of liquid for each dose, not a regular household spoon.
Methyldopa controls high blood pressure but does not cure it. Continue to take methyldopa even if you feel well. Do not stop taking methyldopa without talking to your doctor. If you suddenly stop taking methyldopa, your blood pressure may increase and you may experience side effects. Your doctor will decrease your dose gradually.
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Your doctor may prescribe a low-salt or low-sodium diet. Follow these directions carefully.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
