Co-Diovan®
Film Coated Tablet
Active ingredients: Valsartan and hydrochlorothiazide
Consumer Medicine Information (CMI)
This leaflet provides important information about using Co-Diovan. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using Co-Diovan.
Where to find information in this leaflet:
1. Why am I using Co-Diovan?
Co-Diovan contains the active ingredients Valsartan and Hydrochlorothiazide.
Co-Diovan is used to treat high blood pressure. Symptoms include headache, fatigue, irregular heartbeat and vision problems. Co-Diovan helps to reduce blood pressure in two ways:
Valsartan helps to lower your blood pressure by blocking the effect of angiotensin II. This is a substance which makes your blood vessels tighten, which raises your blood pressure. When Valsartan blocks it, your blood vessels become relaxed, making it easier for blood to flow and thus helping to lower your blood pressure.
Hydrochlorothiazide is a diuretic (water pill) type of medicine. It helps in reducing the amount of excess fluid in the body by increasing the amount of urine produced and thereby helps in lowering your blood pressure.
2. What should I know before I use Co-Diovan?
