Aliskiren/ hydrochlorothiazide is used for:
Treating high blood pressure in certain patients. It may also be used for other conditions as determined by your doctor.
Aliskiren/hydrochlorothiazide is a direct renin inhibitor and thiazide diuretic combination. The direct renin inhibitor works by relaxing blood vessels. The diuretic helps the kidneys to remove fluid from the body, which lowers blood pressure and helps the heart to pump blood more easily.
