Great news if you take valsartan for high blood pressure and are wondering if you can get a prescription online — you can, and HealthTap can help.

Valsartan is a prescription drug that requires you to consult with a doctor before receiving your prescription. There are two easy ways to do that:

  1. Schedule an appointment with your HealthTap primary care doctor.

  2. Connect with a HealthTap urgent care doctor in minutes.

Once they’ve evaluated you* and determined that valsartan is the right drug for you, your HealthTap online doctor can send the prescription to your nearest pharmacy. Our app will even help you find the lowest price at the five pharmacies closest to you. 

*In some cases, you may need to travel to an in-person site for tests that can’t be performed over a video call.

What is valsartan and how does it work?

Valsartan is what’s called an angiotensin II receptor blocker — in plain English, it helps relax your blood vessels and thereby lowers blood pressure.

It’s prescribed to children and adults, and can be used alone or in combination with other drugs to treat a variety of ailments:

  • High blood pressure (most common).

  • Heart failure.

  • After a heart attack to increase the likelihood of survival.

How is it taken and what’s the right dosage?

Valsartan is available in tablets or as a liquid suspension. Your doctor will usually only prescribe the liquid if you’re unable to swallow the tablets. 

For the treatment of high blood pressure, it’s generally taken once per day with or without food. As we mentioned above, valsartan is sometimes prescribed in combination with other drugs and almost always with lifestyle changes that can help lower blood pressure such as:

  • A lower-sodium diet.

  • More exercise.

  • Quitting smoking.

  • Drinking alcohol in moderation.

For dosage guidelines, consult with your doctor. The right dosage may change from person to person and there’s no one-size-fits-all recommendation.

What are the benefits of taking valsartan?

High blood pressure is a serious condition and if left untreated, can have life-threatening or fatal results. Damage from high blood pressure can lead to heart disease, heart attack, heart failure, stroke, kidney failure, blindness, and more.

Taking valsartan, in combination with other drugs and changes to your lifestyle, can reduce your risk of any of these ailments and potentially prolong your lifespan.

Side effects

Side effects of valsartan include:

  • Headache.

  • Fatigue.

  • Nausea.

  • Diarrhea.

  • Pain in your stomach, back, and/or joints.

  • Blurred vision.

  • Cough.

  • Rash.

These usually go away quickly. If they don’t, or if they’re severe, call your doctor.

Also, call your doctor immediately if you experience any of these serious side effects:

  • Swelling in your face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs

  • Hoarseness.

  • Difficulty breathing or swallowing.

  • Unexplained weight gain.

Drug interactions and things to watch out for

Tell your doctor if you:

  • Have diabetes and take aliskiren. Your doctor will probably recommend against valsartan if this is the case.

  • Take angiotensin-converting enzyme (ACE) inhibitors.

  • Are taking any over-the-counter medications, vitamins, or supplements.

  • Have ever had a blockage in your bile duct, or heart, kidney, or liver disease.

  • Are breastfeeding, because you shouldn’t breastfeed while taking valsartan.

  • Have any issues with fainting or lightheadedness — valsartan can exacerbate those issues.

Does valsartan increase the need to urinate?

Not on its own, no.

Some high blood pressure medications are known as “water pills”, or diuretics, and work by increasing the flow of urine to decrease the amount of water in your body, which lowers blood pressure.

Valsartan isn’t one of these, but it’s present in some drugs that do cause frequent urination. The brand name Diovan, for example, is a combination of valsartan and the drug hydrochlorothiazide—which is a water pill and will cause you to urinate.

What’s the difference between valsartan and losartan?

Losartan is another angiotensin receptor blocker. It’s similar to valsartan, but valsartan is preferred for patients who have recently had a heart attack.

HealthTap doctors can prescribe valsartan online

HealthTap doctors can help you manage your blood pressure medication, and manage your other medications to prevent any unwanted or unintended interactions. They can write you a prescription for valsartan and refill prescriptions when you need—including when you’re traveling.

The best part is, you don’t even have to leave the comfort of your home to talk with your doctor. And once you’ve done an initial appointment, you can text any follow-up questions or clarifications to your doctor free of charge.
