Aldomet (active ingredient: methyldopa) is a prescription medication indicated for:

  • Hypertension: Aldomet is used for the management of hypertension (high blood pressure) in adults and children. It can be used as monotherapy or in combination with other antihypertensive agents.

Aldomet belongs to a class of drugs known as centrally acting alpha-2 adrenergic agonists, which work by stimulating alpha-2 receptors in the brain, leading to a decrease in sympathetic outflow from the central nervous system and a subsequent reduction in blood pressure.

Uses and Dosage

Methyldopa tablets are typically taken by mouth, with or without food, as directed by a healthcare provider. Methyldopa tablets should be swallowed whole and should not be crushed or opened. Methyldopa should be taken at the same time every day. Patients taking Aldomet should undergo regular blood pressure checks and may need regular blood tests to monitor liver function and other parameters. Patients should inform their healthcare provider if they experience any side effects while taking Methyldopa.

  • Adults: The usual initial dose is 250 mg taken 2 to 3 times a day by mouth. This may be increased gradually up to a maximum daily dose of 3,000 mg, which is split into 2 to 4 smaller doses taken throughout the day.
  • Children: The usual starting dose is 10 mg per kilogram of body weight per day taken by mouth, split into 2 to 4 smaller doses taken throughout the day. It may be increased gradually up to a maximum daily dose of 65 mg per kilogram of body weight or 3,000 mg per day, whichever is less.
