Coupons for Diovan

Diovan (also known as Valsartan) is a medication used to treat high blood pressure and congestive heart failure. It can also help people improve their odds of survival after a heart attack. Classified as a an angiotensin II receptor antagonist, Diovan works by preventing blood vessels from tightening, allowing the heart to function better and the blood to move more freely. It can also be used to treat kidney disease in those with high blood pressure or diabetes.

Dosage Instructions

Diovan is administered in tablet form. For treating high blood pressure, it is taken once a day. For treating heart problems, it is taken twice daily. Diovan can be taken with or without food.

If you miss a dose, try to take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your normal dosing schedule. Do not take more than one dose per day.

You may initially take a low dose, with your doctor increasing it as needed. Diovan does not work immediately; although your blood pressure may drop after two weeks of use, it may take four weeks for it to take full effect. Do not stop taking Diovan if you feel better. You should continue to take it until your doctor instructs you otherwise.

Special Precautions

Diovan is not for everyone. Inform your doctor if you have the following conditions:

  • Allergies to medication
  • You are taking other medications, as drug-drug interactions can occur
  • You have had bile duct blockages or heart, liver or kidney disease
  • You are pregnant or breast-feeding. Diovan can cause serious effects on unborn babies, especially in the second and third trimesters.

Diovan can cause fainting and dizziness when rising too quickly from a lying position. Get up slowly and place your feet on the ground for several minutes before standing up to avoid these side effects.

A drop in blood pressure can be caused by vomiting, diarrhea, lack of fluids and excessive sweating. Let your doctor know if you have these conditions while taking Diovan.

Ask your doctor about using salt substitutes that contain potassium. Be sure to follow any low-salt diet that your doctor recommends while taking Diovan.

Side Effects

Diovan cause minor side effects, such as headache, nausea, diarrhea, excessive tiredness, rash, cough, blurry vision and back, stomach and joint pain. Call your doctor immediately if you experience side effects, including swallowing or breathing problems, weight gain, hoarseness and swelling.

Although rare, there have been cases of Diovan causing kidney failure due to the breakdown of skeletal muscle tissue. Symptoms include fever, tiredness, weakness, muscle pain and dark-colored urine. Call your doctor immediately if you experience any of these symptoms.

Important Information You Should Know

Be sure to keep all doctor appointments. You may have to have regular laboratory and blood pressure tests to ensure that Diovan is working effectively. If you start taking any new medications while on Diovan, be sure to inform your doctor, as serious interactions can occur.
