Cozaar

Generic name: Losartan potassium

Why is Cozaar prescribed?

Cozaar is used in the treatment of high blood pressure. It is effective when used alone or with other high blood pressure medications, such as diuretics that help the body get rid of water.

Cozaar is also used to slow the progress of kidney disease caused by type 2 diabetes (the type of diabetes that doesn't require insulin shots). It is the first of a new class of blood pressure medications called angiotensin II receptor antagonists. Cozaar works, in part, by preventing the hormone angiotensin II from constricting the blood vessels, which tends to raise blood pressure.

Most important fact about Cozaar

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

How should you take Cozaar?

Cozaar can be taken with or without food.

Take it at the same time each day. For example, if you take the medication every morning before or after breakfast, you will establish a regular routine and be less likely to forget your dose.

• If you miss a dose...
  Take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular schedule.

• Storage instructions...
  Store at room temperature. Keep in a tightly closed container, away from light.

What side effects may occur?

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

• Side effects may include:
  Cough, dizziness, upper respiratory infection

Other side effects, such as weakness and chest pain, have been reported by people taking Cozaar for diabetic kidney disease. Severe allergic reactions, including swelling of the face and throat, are also a possibility.
