Valsartan, also known by its brand name, Diovan, is an angiotensin II receptor blocker (ARB). It's used to treat high blood pressure in adults and children. It's also used to lower the risk of serious heart-related problems in adults with heart failure or in adults after a heart attack. Valsartan (Diovan) is available as a lower-cost generic and comes as a tablet and liquid. The dosage depends on your condition, but it's typically taken by mouth once or twice per day. Potential side effects of valsartan (Diovan) include dizziness and fatigue.
High blood pressure in adults and children
Lower the risk of hospitalization for heart failure in adults
Lower the risk of death after a heart attack in adults
Valsartan (Diovan) is an angiotensin II receptor blocker (ARB). It lowers blood pressure by blocking angiotensin II, a hormone that's naturally found in the body.
Angiotensin II typically raises your blood pressure by squeezing the blood vessels. It also tells your body to release another hormone called aldosterone. Aldosterone raises the amount of water your body absorbs, which also raises your blood pressure.

A first-choice medication for high blood pressure, heart failure, and heart attack for many people
Taken typically once per day, but sometimes twice per day
Available as a tablet and a liquid
Can be used in children
Takes about 2-4 weeks to see full benefits of valsartan (Diovan) for high blood pressure
Might not work as well for Black people
Not safe to use during pregnancy
Make sure to mark your calendar with your appointments to see your primary care provider (PCP) or cardiologist and to get any blood work done when you take valsartan (Diovan). Your care team will order tests (e.g., potassium level, kidney function, blood pressure) during treatment and might change your dose of valsartan (Diovan) based on your lab results.
After starting valsartan (Diovan), you'll probably notice a drop in blood pressure within a week. But it can take several weeks to get the full blood pressure-lowering effect of the medication. Sometimes, your PCP or cardiologist might need to adjust your dose of valsartan (Diovan) to find a dose that works best for you. Continue taking valsartan (Diovan) as directed by your healthcare team.
If you're taking valsartan (Diovan) 4 mg/mL liquid, store the medication at room temperature. Make sure to only use a medication dose cup or oral syringe from the pharmacy to measure the dose. Don't use household spoons; they might not be accurate and using them can cause you to take the wrong dose of valsartan (Diovan).
While you're taking valsartan (Diovan), you're recommended to measure and record your blood pressure at home and bring a record to your medical appointments. This will help your PCP or cardiologist see how well the medication is working for you and guide any dose changes.
You can take valsartan (Diovan) with or without food. But nausea and upset stomach are common, so taking it with food might help prevent or ease these side effects.
You might feel dizzy when you start taking valsartan (Diovan), and when the dose is raised. This should get better over time as you continue taking the medication and your body gets used to your new blood pressure.
Take valsartan (Diovan) exactly as prescribed. Don't change your dose or stop taking it suddenly without talking to your primary care provider or cardiologist first. Otherwise, your blood pressure might rise quickly. Ask your prescriber about the safest way to stop valsartan (Diovan).
Make sure to tell your care team about all the medications you're taking before you start valsartan (Diovan). Also, don't start taking any new medications without talking to your care team first. Since valsartan (Diovan) can interact with other medications, it's best for your care team to check that all your medications are safe for you to take.
Don't take non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin), while taking valsartan (Diovan) unless your prescriber specifically said it was safe for you to do so. This is because taking NSAIDs and valsartan (Diovan) together can cause or worsen kidney problems.
Valsartan (Diovan) can raise your potassium levels, which can be serious. Ask your PCP or cardiologist if you need to limit foods that are high in potassium. Make sure to tell your care team about all the medications you're taking to lower your risk. Contact your prescriber if you experience nausea, vomiting, or muscle weakness because these might be signs of high potassium levels.
It's important to eat healthy diet that's low in salt while you're taking valsartan (Diovan). Ask your care team to help you plan healthy meals, such as ones that include low-fat milk or yogurt, whole-grains, and vegetables.
If you're pregnant or thinking of getting pregnant, contact your PCP or cardiologist right away. Valsartan (Diovan) isn't safe to take during pregnancy, so you'll need to switch to a medication that's safer for your baby.
Valsartan (Diovan) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Don't take valsartan (Diovan) if you're pregnant because the medication can cause severe harm your unborn baby. This medication can affect how well the unborn baby's kidneys develop and work, which can be life-threatening.
Stop taking valsartan (Diovan) and let a member of your healthcare team know right away if you find out that you're pregnant during treatment. Discuss with your primary care provider or cardiologist about taking a different medication that's safer to treat your blood pressure if you're pregnant or thinking of becoming pregnant.
Risk factors: Not enough fluid in your body | Having diarrhea or vomiting for a long time | Low salt levels in your body | Taking higher doses of diuretic mediations
Although rare, valsartan (Diovan) can cause your blood pressure to drop too much. This can make you feel dizzy, tired, or lightheaded. Having these symptoms of low blood pressure is more common when you first start valsartan (Diovan) or when your dose gets raised. You're also at risk if you're dehydrated or if you have medical conditions that cause you to become dehydrated, such as too much diarrhea or vomiting.
Make sure to stay well-hydrated. Be sure to sit down slowly while holding onto something if your blood pressure drops too much and you feel dizzy. Let your care team know if your blood pressure gets too low or if you feel dizzy, lightheaded, faint, tired, or confused while you're taking valsartan (Diovan). Get medical help right away if you fall and hit your head.
Risk factors: Severe heart failure | Kidney problems | Not enough fluid in your body | Taking other medications that can cause kidney damage
Although valsartan (Diovan) is sometimes used to protect the kidneys, it's also possible for the medication to affect your kidneys in a way that causes them to not work as well. This can happen to anyone. But the effects can be more serious in people with severe heart failure, people with certain kidney problems, or people who take medications that can worsen kidney function.
Your primary care provider or cardiologist might order lab tests every so often during treatment to make sure your kidneys are healthy and working properly. Your care team might recommend that you stop taking the medication if you develop kidney problems (or if your kidney problems worsen) while you're taking valsartan (Diovan). Let your primary care provider or cardiologist know if you're urinating less often than usual, as this could be a sign that your kidneys aren't working as well.
Risk factors: Taking other medications that can raise potassium levels | Kidney problems
ARBs like valsartan (Diovan) can cause high potassium levels. Your risk is higher if you take valsartan (Diovan) with other medications that can raise potassium, such as spironolactone (Aldactone) or eplerenone (Inspra). Tell your healthcare team right away if you experience signs of high potassium levels, such as nausea, muscle weakness, or abnormal heartbeat. You'll probably need your potassium levels checked. If left untreated, high potassium levels can be dangerous.
In general, your dose will depend on things like why you need to take valsartan (Diovan), how well it's working to lower your blood pressure, if you're taking a diuretic (water pill), and if you're having side effects.
