Can Diovan Cause Kidney Failure?

Like most drugs, Diovan has side effects. There is speculation regarding the possibility of the drug causing kidney failure. Although the active ingredient in Diovan actually blocks the chemicals that cause kidney failure, one of the side effects of Diovan is kidney problems for those who already have the disease.

What is Diovan?

• Diovan is the trade name for the drug Valsartan, which treats high blood pressure and congestive heart failure. According to Novartis, the maker of Diovan, the drug has helped millions of patients over the past decade.

Inside Diovan

• Diovan belongs to a class of medication called Angiotensin II Receptor Blockers, or ARBs. ARBs control high blood pressure by widening blood vessels and allowing blood to flow easier. ARBs treat heart failure, and they prevent kidney failure caused by high blood pressure or heart failure.

The Evil of Angiotensin II

• ARBs "block" Angiotensin II, which is a deadly chemical that causes blood vessels to narrow. This narrowing constricts the vessels and can cause high blood pressure. That can lead to heart and kidney failure.

Side Effects and Kidney Failure

• One of the serious side effects of Diovan is that kidney problems of those with a pre-existing kidney ailment may worsen. Please alert your doctor to any pre-existing kidney problem before taking Diovan. In any case, your doctor should check your kidney function before prescribing this drug.

Other Side Effects

• Other documented side effects of Diovan include sensitivity to light, headaches, dizziness, an increase in blood potassium levels, coughing, fatigue and diarrhea. Some have also experience joint, back and stomach pain.

Diovan and You

• See your doctor if you have high blood pressure or heart issues. Diovan is only available through a doctor's prescription.
