About Valsartan

Valsartan belongs to a class of medicines known as angiotensin II receptor antagonist, which help to control high blood pressure. Angiotensin II is a substance in the body that causes vessels to tighten, thus causing your blood pressure to increase. Valsartan works by blocking the effect of angiotensin II. As a result, blood vessels relax and blood pressure is lowered.

Valsartan is used treat:

  • High blood pressure in children and adolescents aged 6 to 18 years.
  • Adult patients after a recent heart attack (‘recent’ here means between 12 hours and 10 days).
  • Symptomatic heart failure in adult patients.

How to use Valsartan

Always take this medicine exactly as your doctor or pharmacist has told you. Valsartan should be taken with a drink of water. The tablet should be taken at the same time each day. This will help you to remember to take it. Valsartan can be taken with or without food.

Dosage

Dosage varies per person and is determined by a doctor depending on the symptoms. The general dosage guidelines are as follows:

Use in children and adolescents (6 to 18 years of age) with high blood pressure:

  • In patients who weigh less than 35 kg the usual dose is 40 mg of valsartan once daily.
  • In patients who weigh 35 kg or more the usual starting dose is 80 mg of valsartan once daily.

In some cases, your doctor may prescribe higher doses. Valsartan oral solution is recommended for children with difficulty swallowing.

Use in adult patients after a recent heart attack:

After a heart attack the treatment is generally started as early as after 12 hours, usually at a low dose of 20 mg twice daily. If necessary, the doctor may decide to increase this dose (see the package leaflet).

Use in adult patients with heart failure:

Treatment starts generally with 40 mg twice daily. If necessary, the doctor may decide to increase this dose (see the package leaflet).

This medicine does not interact with alcohol.

Valsartan may in rare cases cause dizziness and affect the ability to concentrate. Before you drive a vehicle, use tools or operate machines, or carry out other activities that require concentration, make sure you know how Valsartan affects you.

If you use too much/forget to use/stop using Valsartan

If you accidentally take more Valsartan than you were told to, contact your doctor, pharmacist or hospital immediately.

If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the dose you missed. Do not take a double dose to make up for a forgotten one.
