Benicar (Olmesartan) : Drug Information

What is Benicar?

Benicar (olmesartan) is a prescription drug. It comes as a film-coated oral tablet and is also available as a generic drug.

It is an angiotensin II receptor antagonist. Olmesartan prevents blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Benicar is used to treat high blood pressure (hypertension) in adults and children at least six years old.

Sometimes, doctors give Benicar together with other blood pressure-lowering drugs as part of combination therapy.

Important Information

Avoid taking Benicar during pregnancy. You should stop using Benicar at once and tell your doctor right away if you become pregnant. This medicine can also cause injury or death to the unborn baby if you keep taking medication during your second or third trimester.

People with diabetes should not use Benicar combined with any medication that contains aliskiren (a blood pressure medicine – available under brand names like Tekturna, Tekamlo, and Amturnide).

If you have a kidney-associated disease, you may also need to avoid taking Benicar with aliskiren.

What to know before taking Benicar?

It is best not to take Benicar if you are allergic to olmesartan.

To ensure Benicar is safe for you, let your doctor know if you have or ever had:
