What ASARTAN HCT is used for
ASARTAN HCT is used to treat high blood pressure.
Candesartan cilexetil is a type of medicine called an angiotensin II - receptor antagonist (or blocker). It mainly works by causing relaxation of blood vessels.
Hydrochlorothiazide is a type of medicine called a diuretic. It works by reducing the amount of excess fluid in the body.
Using these two medicines together will lower your blood pressure more than using either one on its own.
Your doctor will have explained why you are being treated with ASARTAN HCT and told you what dose to take.
You must follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
Your doctor may prescribe this medicine for another use.
Ask your doctor if you want more information.
