About Valsartan (Generic Diovan)
How does it work?
Valsartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). It works by blocking a hormone called angiotensin II, which narrows blood vessels and increases blood pressure. Blocking this hormone helps relax blood vessels, reduce blood pressure and improve blood flow. This makes Valsartin an effective medication for people with high blood pressure and heart failure.
What does it treat?
Valsartan is primarily used to treat high blood pressure (hypertension), a medical condition that happens when the force of blood against artery walls gets too high. It can also be prescribed to manage heart failure and improve survival after a heart attack.
What forms does it come in?
Valsartan comes as tablets or capsules that you take by mouth. These are available in different strengths, allowing for flexible dosing.
Valsartan vs. Diovan
Valsartan and Diovan are the same medication. They both contain the active ingredient Valsartan and treat elevated blood pressure levels in the same way. Diovan is one of the brand names for Valsartan—the generic version—so it may cost more.
How much will it cost?
Dr. B offers online consultations for $15—which is less than most copays. If a high blood pressure prescription is appropriate, your out-of-pocket medication cost will depend on your insurance and where you decide to get your prescription filled. With a drug discount card, prices for Valsartan 40 mg (30 tablets) start at $13.24.

How do you take this medication?
You take this hypertension medicine by mouth, with or without food, once or twice a day as directed by your licensed medical provider.
High blood pressure is a long-term (chronic) condition that can harm your organs. Medications for blood pressure are not a one-time cure. This medicine doesn't provide a complete cure for high blood pressure, so it's important to continue taking it, even if you start feeling better. If you stop taking it suddenly, this could cause dangerous problems, like heart attack or stroke. Follow your medical provider's instructions carefully.
Also, please keep in mind that it may take some time for this medication to achieve its full effect in managing your blood pressure. Don't be discouraged if you don't notice immediate changes. Continue taking your medication as prescribed, and consult with your healthcare provider if you have any questions or concerns.
What happens if I miss a dose?
If you miss a dose, take it as soon as you remember—unless it's close to the time for your next dose. If that’s so, skip the missed dose and ake the next dose at your scheduled time. Don't take extra medication to make up for what you’ve missed.
What happens if I take too much?
Taking too much Valsartan increases the risk of developing symptoms like severe dizziness or fainting. If you’ve taken too much, call your medical provider or local poison control center (800-222-1222) immediately.
