Tell your doctor if you are pregnant or plan to become pregnant. Do not take valsartan if you are pregnant.

Valsartan may cause death or serious injury to the fetus when taken in the last 6 months of pregnancy.
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 (condition in which the heart is unable to pump enough blood to the rest of the body) and to improve survival after a heart attack. Valsartan 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.
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
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 or heart attack, it is usually taken twice a day with or without food. To help you remember to take valsartan, take it at around the same time(s) 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. Your blood pressure may decrease during the first 2 weeks of your treatment, but it may take 4 weeks for you to notice the full benefit of valsartan. Continue to take valsartan even if you feel well. Do not stop taking valsartan without talking to your doctor.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.
