Buy Methyldopa (Aldomet) Online from a Canadian Pharmacy



Aldomet (methyldopa) is a trusted FDA-approved medication for managing hypertension, effectively reducing blood pressure by relaxing blood vessels. It is suitable for adults and neonates and offers flexible dosing options in both injectable and tablet forms. With a favorable safety profile, Aldomet is especially beneficial for patients seeking a well-tolerated treatment. When used under medical supervision, it provides reliable blood pressure control, contributing to cardiovascular health and reducing the risk of hypertension-related complications.

Product Overview

Aldomet (methyldopa) is an FDA-approved medication primarily used to treat high blood pressure (hypertension). It is available in injectable solution (50mg/ml) and tablet form (250mg and 500mg). Adults typically start with a dose of 250 mg orally every 8-12 hours, which can be adjusted based on response. For hypertensive crises, the dosage may be higher. Dosage adjustments are also recommended for those with renal impairment.

In treating hypertension, the usual dosage is 2.5-5 mg/kg orally or intravenously every 8 hours. It is essential to take Aldomet as prescribed, at the exact times each day, and continue taking it even if you feel well. Aldomet works by stimulating the central nervous system to reduce the activity of the sympathetic nervous system, leading to relaxed blood vessels and lower blood pressure. Common side effects include lightheadedness, drowsiness, and headaches.

Patients with a history of liver disease or dysfunction should use Aldomet with caution. During treatment, it is also essential to monitor for signs of hemolytic anemia and liver disorders. This medication should be stored at room temperature, away from light and moisture, and out of reach of children and pets. Patients with active liver diseases should not use it, those allergic to its components, or those taking monoamine oxidase inhibitors.

  • Typically, it is taken 2 to 4 times daily.
  • Begin this medication or any increase in dosage in the evening to reduce the risk of side effects.
  • If the doses are unequal, take the larger dose at bedtime.

How Does Aldomet Work?

Aldomet (methyldopa) works by stimulating the central nervous system to produce alpha-2 adrenergic receptors, which in turn reduce the activity of the sympathetic nervous system. This leads to a decrease in the release of norepinephrine, a neurotransmitter responsible for increasing blood pressure. As a result, blood vessels relax and dilate, leading to a reduction in blood pressure. methyldopa also acts directly on the blood vessels, causing them to relax and further lowering blood pressure.

  • Methyldopa therapy may result in a positive Coombs test, hemolytic anemia, and liver disorders. These conditions can lead to severe complications if not properly managed.
  • 10 to 20 percent of patients on methyldopa develop a positive direct Coombs test, usually between 6 and 12 months of therapy. The risk is lowest with a daily dosage of 1g or less.
  • A positive direct Coombs test does not always indicate hemolytic anemia but can be associated with it.
  • Before starting methyldopa, it is advisable to perform a blood count for a baseline and periodically during therapy to detect hemolytic anemia. A direct Coombs test should also be done before treatment and 6 and 12 months after starting.
  • If Coombs-positive hemolytic anemia occurs, methyldopa should be discontinued. The anemia usually remits promptly, but corticosteroids may be needed if it does not.
  • Conducting direct and indirect Coombs tests is essential for patients needing a transfusion. A positive direct Coombs test does not impact the blood typing or cross-matching process.
  • Fever, sometimes with eosinophilia or liver function abnormalities, may occur within the first 3 weeks of therapy. Jaundice may appear within the first 2 to 3 months.
  • Rarely fatal hepatic necrosis has been reported. Periodic liver function tests are recommended, especially during the first 6 to 12 weeks of therapy or if unexplained fever occurs. If abnormalities or jaundice appear, methyldopa should be stopped.
  • Reversible reductions in white blood cell count, primarily affecting granulocytes, and rare cases of granulocytopenia and thrombocytopenia have been reported. These counts return to normal upon discontinuation of the drug.



  • Use methyldopa cautiously in patients with a history of liver disease or dysfunction.
  • Some patients may experience swelling or weight gain, which can be managed with a diuretic. Discontinue methyldopa if swelling progresses or heart failure symptoms appear.
  • Blood pressure may rise after dialysis in patients taking methyldopa, as the drug is removed during the procedure.
  • Rarely, involuntary movements may occur in patients with severe cerebrovascular disease. Stop therapy if these movements occur.

Laboratory Tests:

  • Perform blood count, Coombs test, and liver function tests before starting therapy and periodically during treatment.

Carcinogenesis, Mutagenesis, Impairment of Fertility:

  • No evidence of tumor formation was seen in mice and rats given methyldopa for two years.
  • methyldopa was not mutagenic in the Ames Test and did not increase chromosomal abnormalities in Chinese hamster ovary cells.
  • Fertility was unaffected in rats at 100 mg/kg/day, but higher doses decreased sperm count and male fertility index.


  • methyldopa falls under Category B for pregnancy, with no evidence of harm to the fetus in animal studies.
  • Limited human studies suggest that methyldopa may improve fetal outcomes during pregnancy.
  • Use methyldopa during pregnancy only if necessary.

Nursing Mothers:

  • methyldopa is present in breast milk. Use caution when prescribing methyldopa to nursing mothers.

Pediatric Use:

  • There are no well-controlled clinical trials in pediatric patients. Dosing information is based on published literature on treating hypertension in children.

Close medical supervision is essential to ensure the medication’s effectiveness and promptly address any potential long-term effects.

What should you avoid while on methyldopa?

  • Avoid taking methyldopa with monoamine oxidase inhibitors (MAOIs) such as isocarboxazid, phenelzine, linezolid, and tranylcypromine.
