Valsartan: Uses, Side Effects, and Drug Interactions

Brand names: ENTRESTO

# Valsartan: What You Need to Know Valsartan is a medication used to treat high blood pressure and heart failure. It works by relaxing blood vessels, which helps blood flow more easily through your body and reduces the strain on your heart. By lowering blood pressure, valsartan helps prevent serious health problems like heart attacks and strokes. Your doctor may prescribe this medicine if other treatments haven't worked well enough or as a first treatment option for managing your blood pressure. When taking valsartan, it's important to follow your doctor's instructions carefully. You should avoid taking certain other medications at the same time, including some blood pressure medicines, pain relievers like ibuprofen, and the mood medication lithium, as these can cause dangerous interactions. Tell your doctor about all medicines you take before starting valsartan. Pregnant women should not take this medication. Common side effects may include dizziness or fatigue, but serious side effects are rare. Always keep taking your medication as prescribed, and report any unusual symptoms to your doctor right away.
