Used for Hypertension
Methyldopa is an oral tablet that's used to treat high blood pressure. It belongs to a group of medications called alpha-2 adrenergic receptor agonists. Because it doesn't last long in your body, it must be taken a few times a day. Methyldopa is preferred over other medications for treating high blood pressure during pregnancy. Some potential side effects include sleepiness, headache, and weakness.

How Methyldopa works
Methyldopa is an alpha-2 adrenergic receptor agonist. It works by signaling the brain to cause your blood vessels to relax. This makes it easier for blood to flow and lowers your blood pressure.

Pharmacist tips for Methyldopa
- You can take methyldopa with or without food. Nausea is a possible side effect of this medication, so if this happens to you, take your doses with something to eat.
- For the most consistent results, take methyldopa at the same times every day.
- It's common to feel sleepy and dizzy when starting methyldopa or after a dose change. These side effects usually improve after a week or two on the same dose. Be careful changing positions during this time, as doing so too quickly can cause you to fall. Let your prescriber know if the side effects are bothersome.
- Methyldopa commonly causes dry mouth. There are mouthwashes, lozenges, and sprays that can help lessen this feeling. Ask your pharmacist if you need help selecting one of these products.
- Let your prescriber know if you're taking any antidepressants or medications for Parkinson's disease. Some of these medications interact with methyldopa and can cause dangerously high blood pressure.
Risks and warnings for Methyldopa
Methyldopa can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Liver problems
- Risk factors: History of or current liver problems
Although rare, methyldopa can cause serious liver problems. In some cases, this can be life-threatening. Because of this, people with liver problems shouldn't take this medication. Be sure to attend all follow-up appointments and complete any blood tests ordered so your care team can track your liver function. If you experience any unusual vomiting, pale stools, dark urine, stomach pain, or yellowing of your skin and whites of your eyes, seek medical attention right away.
Breakdown of red blood cells (hemolytic anemia)
- Risk factors: Positive Coombs test | Using methyldopa for a long time
Although very rare, taking methyldopa for a long time can cause a serious condition called hemolytic anemia. This life-threatening problem causes your body to destroy your red blood cells faster than they can be replaced. This typically happens between 6 and 12 months after starting methyldopa. If you're going to be taking this medication for a long time, you'll have to get regular blood tests done to watch for early signs of this condition.
Low white blood cell and platelet count
Rarely, methyldopa can lower the number of white blood cells and platelets in your body. White blood cells help your body fight infections, and without enough of them, you can get sick more easily and take longer to recover. Platelets help your blood clot to stop bleeding. You'll have to have blood tests done regularly while you're taking methyldopa to make sure your blood cells are at a normal level. If you experience changes in your blood cells, know that it's reversible. These side effects will go away once you stop taking the medication.
