Irbesartan / Hydrochlorothiazide Sandoz- Hydrochlorothiazide uses, dose and side effects


150 mg / 12.5 mg and 300 mg / 25 mg film-coated tablets
irbesartan / hydrochlorothiazide

What Irbesartan / Hydrochlorothiazide Sandoz is and what it is used for

Irbesartan / Hydrochlorothiazide Sandoz is a combination of two active substances, irbesartan and hydrochlorothiazide .

Irbesartan belongs to a group of medicines called angiotensin II receptor antagonists. These cause the blood vessels to relax and the blood pressure to drop.

Hydrochlorothiazide is a group of medicines called diuretics ( diuretic agents).

The two active substances in Irbesartan / Hydrochlorothiazide Sandoz work together to lower blood pressure more than if the substances were given separately.

Irbesartan / Hydrochlorothiazide Sandoz is used for treating high blood pressure, as treatment with irbesartan or hydrochlorothiazide alone has not provided adequate control of blood pressure.

Irbesartan/hydrochlorothiazide contained in Irbesartan / Hydrochlorothiazide Sandoz may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
