What is this medication used for?

If your blood pressure is elevated for a prolonged time, it may damage the blood vessels and the organs. This increases the risk of cardiovascular diseases, such as a stroke or a heart attack. Co-Diovan reduces blood pressure in two ways. The medicine is composed of the following active substances:

  • Valsartan, an angiotensin II receptor antagonist. This drug dilates the blood vessels and thereby causes a drop in blood pressure.
  • Hydrochlorothiazide, a diuretic that causes extra moisture loss through the kidneys. This also causes a drop in blood pressure.

How to use Co-Diovan?

Always take the medicine at a fixed time in the morning. You can take this medicine with or without food. Take the tablet without chewing with some water. If you forget to take the tablet, just proceed with the usual schedule. Never take a double dose to compensate for the forgotten tablet.
