Indications
Diovan HCT is a medication that can treat hypertension (high blood pressure) or heat failure. It is a combination of two drugs: valsartan and hydrochlorothiazide. The combination of these two drugs can help to reduce the amount of fluid buildup in the body and therefore improve blood flow throughout the body. Diovan HCTZ is an effective treatment for hypertension and can be taken either as a single-drug or combined with other medications.
Valsartan is an angiotensin receptor blocker (ARB) that works by relaxing blood vessels so that blood can flow more easily, and hydrochlorothiazide is a diuretic or "water pill" that helps to eliminate excess fluid from the body, which can also help to lower blood pressure. It acts as a diuretic which reduces the amount of fluid and sodium in the kidneys.
Uses and Dosage
Diovan HCT comes in the form of tablet to be taken orally once a day with or without food, as instructed by a healthcare professional. To avoid having to urinate during the night, take the tablet at least 4 hours before bedtime if it causes more frequent urination. If taking cholesterol-lowering medications such as cholestyramine or colestipol, take Diovan HCTZ at least 4 to 6 hours before or after those medications.
The dosage of Diovan HCTZ is determined by the medical condition and response to treatment of the individual. Regular use of Diovan HCT tablet, at the same time each day, achieve the best results, even if there are no noticeable symptoms. Consult with a healthcare professional if there is no improvement or if there is a worsening of symptoms such as high blood pressure readings.
