Irbesartan is used alone or in combination with other medications to treat high blood pressure. It is also used to treat kidney disease caused by diabetes in patients with type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood) and high blood pressure. Irbesartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.
Irbesartan comes as a tablet to take by mouth. It is usually taken once a day with or without food. To help you remember to take irbesartan, take it at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take irbesartan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of irbesartan and gradually increase your dose.
Irbesartan controls high blood pressure but does not cure it. It may take 2 weeks for you to notice the full benefit of irbesartan. Continue to take irbesartan even if you feel well. Do not stop taking irbesartan without talking to your doctor.
Irbesartan is also used sometimes to treat congestive heart failure (condition in which the heart is unable to pump enough blood to the rest of the body). Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
