Valsartan is a common blood pressure medicine that many doctors choose because it works well and is usually easy to tolerate. It's an angiotensin receptor blocker (ARB), which means it relaxes blood vessels so blood flows more smoothly. That lowers blood pressure and eases stress on the heart.
People take valsartan for high blood pressure, heart failure, and to lower risk after a heart attack. It helps prevent hospital visits for heart failure and can improve symptoms like shortness of breath and swelling when used correctly.
Dosage depends on why you're taking it and your other medical conditions. For adults with high blood pressure, many doctors start at 80 mg once daily and adjust between 80–320 mg once daily. For heart failure, the usual approach is to start lower (for example 40 mg twice daily) and slowly increase toward 160 mg twice daily as tolerated. Your provider will choose a dose that fits your age, kidney function, and other meds.
Take valsartan the same time each day. You can take it with or without food. If you miss a dose, take it when you remember unless it's almost time for the next one—don't double up.
Common side effects are dizziness, lightheadedness, and sometimes tiredness. These usually show up when you first start or when your dose goes up. Less common but more serious issues include high potassium (hyperkalemia) and reduced kidney function.
Avoid valsartan if you're pregnant or planning to become pregnant—ARBs can harm the fetus. Also, don't combine valsartan with an ACE inhibitor unless a specialist recommends it; the combo raises the risk of high potassium and kidney problems.
Watch for interactions: potassium supplements, potassium-sparing diuretics (like spironolactone), and some salt substitutes can boost potassium levels. NSAIDs (ibuprofen, naproxen) can lower how well valsartan works and may increase kidney risk, especially if you’re dehydrated or already have reduced kidney function.
Your doctor will usually check blood pressure, kidney tests, and blood potassium within a few weeks of starting or changing the dose. Keep those follow-ups—small lab changes are common and usually manageable if caught early.
When to call your doctor: if you get severe dizziness, fainting, very low urine output, swelling of the face or throat, or muscle weakness (possible signs of high potassium). For mild dizziness, sit or lie down until it passes and avoid driving until you know how valsartan affects you.
If you need to buy valsartan, use a licensed pharmacy and always keep a valid prescription. Online pharmacies can be safe, but check for a real business address, pharmacist contact, and verified licensing. If a deal seems too cheap or the site avoids prescriptions, walk away.
Valsartan works for millions, but it needs simple common-sense care: take the right dose, get labs checked, avoid risky drug mixes, and speak up about side effects. That keeps you safer and gets the best results from the medicine.
