Methyldopate

Pronunciation

Generic Name: methyldopate (meth-ill-DOE-pate)
Brand Name: Generic only. No brands available.

Methyldopate is used for:

Treating high blood pressure. It may be used with other high blood pressure medicines. It may also be used for other conditions as determined by your doctor.

Methyldopate is an alpha-2 receptor agonist. It reduces elevated blood pressure by relaxing and dilating (widening) blood vessels. Blood flows more freely and at a lower pressure through dilated blood vessels.

Do NOT use methyldopate if:

  • you are allergic to any ingredient in methyldopate
  • you have liver disease, severe kidney problems, a liver reaction caused by past use of methyldopate, or a history of anemia caused by your immune system
  • you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days

Contact your doctor or health care provider right away if any of these apply to you.

Some MEDICINES MAY INTERACT with methyldopate. Tell your health care provider if you are taking any other medicines, especially any of the following:
