How can I avoid getting dizzy when I take Diovan?

Dizziness is a fairly common side effect when you take Diovan (valsartan), particularly when you start treatment. Diovan is prescribed for high blood pressure and heart failure, and to increase the odds of long-term survival after a heart attack. It lowers blood pressure by relaxing and dilating the blood vessels, allowing blood to flow more easily. However, the reduction in blood pressure can make you feel lightheaded and dizzy, at least until your body adjusts.

Dizziness may be especially pronounced when you stand up from a seated or reclining position. To minimize it, change positions slowly. When you get out of bed in the morning, first sit with your feet flat on the floor for a few minutes, and then stand up slowly.

Becoming dehydrated may also increase your risk of dizziness when you take Diovan. Talk to your doctor about ways to stay hydrated, including how much fluid you should be drinking.  

If dizziness persists or is severe, talk to your doctor. He or she may be able to adjust your dose of Diovan, or recommend other ways to minimize dizziness.
