1. What is Casaro HCT and what is it used for

Casaro HCT is used to treat high blood pressure (hypertension) in adult patients. It contains two active substances: candesartan cilexetil and hydrochlorothiazide. Their combined effect reduces the patient's blood pressure.

• Candesartan cilexetil belongs to a group of medicines called angiotensin II receptor antagonists. Its action is to relax and dilate blood vessels. This helps to lower blood pressure.
• Hydrochlorothiazide belongs to a group of medicines called diuretics (water pills). It helps the body get rid of water and salts, such as sodium, in the urine. This helps to lower blood pressure.

The doctor may prescribe Casaro HCT if the patient's blood pressure cannot be reduced by taking only candesartan cilexetil or only hydrochlorothiazide.

2. Important information before taking Casaro HCT

When not to take Casaro HCT

In case of doubt whether any of the above points apply to the patient, they should consult their doctor or pharmacist before taking Casaro HCT.

Warnings and precautions
