What is Avalide (Irbesartan/Hydrochlorothiazide) prescribed for?

High blood pressure is the measure of the force of blood pushing against blood vessel walls. Hypertension is dangerous because it makes the heart work harder to pump blood out to the body and contributes to the hardening of arteries, stroke, kidney disease and to heart failure.

This medication is a combination of 2 drugs, Irbesartan and Hydrochlorothiazide.  This medication’s uses for treatment are for lowering high blood pressure, helping to prevent strokes, heart attacks, and kidney problems.

Irbesartan is an angiotensin receptor blocker.  It works by relaxing the blood vessels, so that the blood may flow more easily. Hydrochlorothiazide is what is known as a “water pill’, and causes the patient to make more urine, which helps your body get rid of extra salt and water.

Take this medication by mouth, as directed by your doctor.  It is usually taken once daily, with or without food. If this medication causes you to urinate more frequently, it is best to take it at least 4 hours before your bedtime to prevent having to get up and to go to the washroom.

If you are using this medication alongside drugs that lower your cholesterol, take Avalide at least 4 hours before or at least 4 to 6 hours after these medications.

Keep in mind that this dosage is based on your medical condition and response to the treatment. Speak with your doctor if your condition does not improve or worsens.
