Valsartan (val-SAR-tan) 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 and to reduce the risk of death after a heart attack. Valsartan controls high blood pressure and heart failure but does not cure them.
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. Take Valsartan exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Continue to take Valsartan even if you feel well. Do not stop taking Valsartan without talking to your doctor.
