Diovan is used for:

Treating high blood pressure alone or with other medicines. It is also used for treating heart failure in patients who do not tolerate angiotensin-converting enzyme (ACE) inhibitors.

Diovan is an angiotensin II receptor blocker. It works by blocking a hormone that tightens blood vessels. This causes blood vessels to relax (dilate), which lowers blood pressure and decreases the workload on the heart.

Do NOT use Diovan if:

you are allergic to any ingredient in Diovan
you are past your first trimester of pregnancy

Contact your doctor or health care provider right away if any of these apply to you.
