Aldomet

Generic name: Methyldopa
Brand names: Aldomet

Why is Aldomet prescribed?

Aldomet is used to treat high blood pressure. It is effective when used alone or with other high blood pressure medications.

Most important fact about Aldomet

You must take Aldomet regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Aldomet; and you must continue taking it even if you are feeling well. Aldomet does not cure high blood pressure; it merely keeps it under control.

How should you take Aldomet?

Take Aldomet exactly as prescribed. Try not to miss any doses. Do not stop taking the drug without your doctor"s knowledge.

Drowsiness may occur when dosage is increased. If your doctor increases the amount of Aldomet you take, start the new dosage in the evening.

--If you miss a dose...

Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.

--Storage instructions...

Keep Aldomet in the container it came in, tightly closed. Store Aldomet tablets at room temperature. Protect from light.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Aldomet.

• More common side effects may include:
  Drowsiness during the first few weeks of therapy, fluid retention or weight gain, headache, weakness

Why should Aldomet not be prescribed?

If you have liver disease or cirrhosis, or if you have taken Aldomet before and developed liver disease, do not take Aldomet.

If you are sensitive to or have ever had an allergic reaction to Aldomet, or if you have been prescribed the oral suspension form of Aldomet and have ever had an allergic reaction to sulfites, you should not take Aldomet.

If you are taking drugs known as monoamine oxidase (MAO) inhibitors, you should not take Aldomet.

Special warnings about Aldomet

Before you begin taking Aldomet, your doctor should perform a complete study of your liver function, and it should be monitored periodically thereafter.

Aldomet can cause liver disorders. You may develop a fever, jaundice (yellow eyes and skin), or both, usually within the first 2 to 3 months of therapy. If either of these symptoms occurs, stop taking Aldomet and contact your doctor immediately. If the fever and/or jaundice were caused by the medication, your liver function should gradually return to normal.

If you have a history of liver disease, Aldomet should be used with caution.

Hemolytic anemia, a blood disorder in which red blood cells are destroyed, can develop with long-term use of Aldomet; your doctor will do periodic blood counts to check for this problem.

Aldomet can cause water retention or weight gain in some people. A diuretic will usually relieve these symptoms.

If you are on dialysis and are taking Aldomet for high blood pressure, your blood pressure may rise after your dialysis treatments.

Aldomet can cause you to become drowsy or less alert, especially during the first few weeks of therapy or when dosage levels are increased. If it affects you this way, driving or operating heavy machinery or participating in any hazardous activity that requires full mental alertness is not recommended.

Notify your doctor or dentist that you are taking Aldomet if you have a medical emergency and before you have surgery or dental treatment.

Possible food and drug interactions when taking Aldomet

If Aldomet is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Aldomet with the following:

Antidepressants known as MAO inhibitors, including Nardil and Parnate
Dextroamphetamine (Dexedrine)
Imipramine (Tofranil)
Iron-containing products such as Ferrous sulfate (Feosol) and Ferrous gluconate (Fergon)

Special information if you are pregnant or breastfeeding

The use of Aldomet during pregnancy appears to be relatively safe. However, if you are pregnant or plan to become pregnant, inform your doctor immediately. Aldomet appears in breast milk and could affect a nursing infant. If Aldomet is essential to your health, your doctor may advise you to discontinue breastfeeding until your treatment is finished.
