Valsartan (patient information)

# IMPORTANT WARNING:
Do not take valsartan if you are pregnant. If you become pregnant while taking valsartan, call your doctor immediately. Valsartan may harm the fetus.

# Why is this medication prescribed
Valsartan is used alone or in combination with other medications to treat high blood pressure. It is also used to treat heart failure in people who cannot take angiotensin-converting enzyme (ACE) inhibitors. Valsartan is in a class of medications called angiotensin II receptor antagonists. It works by blocking the action of certain chemicals that tighten the blood vessels, so blood flows more smoothly.

# How should this medicine be used?
Valsartan comes as a tablet to take by mouth. For the treatment of high blood pressure, it is usually taken once a day with or without food. For the treatment of heart failure, it is usually taken twice a day with or without food.To help you remember to take valsartan, take it 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 valsartan 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 valsartan and gradually increase your dose.
Valsartan controls high blood pressure and heart failure but does not cure them. Continue to take valsartan even if you feel well. Do not stop taking valsartan without talking to your doctor.
