Contents of the pack and other information
Irbesartan Hydrochlorothiazide Zentiva is a combination of two active substances, irbesartan and hydrochlorothiazide.
Irbesartan belongs to a group of medicines known as angiotensin II receptor antagonists. Angiotensin
II is a substance produced in the body that binds to receptors in blood vessels causing them to tighten. This results in an increase in blood pressure. Irbesartan prevents the binding of angiotensin II to these receptors, causing the blood vessels to relax and the blood pressure to lower.
Hydrochlorothiazide is one of a group of medicines (called thiazide diuretics) that causes increased urine output and so causes a lowering of blood pressure.
The two active ingredients in Irbesartan Hydrochlorothiazide Zentiva work together to lower blood pressure further than if either was given alone.
if you are allergic to irbesartan or any of the other ingredients of this medicine (listed in section 6)
if you are allergic to hydrochlorothiazide or any other sulfonamide-derived medicines
if you are more than 3 months pregnant. (It is also better to avoid Irbesartan Hydrochlorothiazide Zentiva in early pregnancy – see pregnancy section)
if you have severe liver or kidney problems
if you have difficulty in producing urine
if your doctor determines that you have persistently high calcium or low potassium levels in your blood

beat), particularly if you are being treated for diabetes.
if you suffer from lupus erythematosus (also known as lupus or SLE)
if you suffer from primary aldosteronism (a condition related to high production of the hormone aldosterone, which causes sodium retention and, in turn, an increase in blood pressure).
if you are taking any of the following medicines used to treat high blood pressure:
an ACE-inhibitor (for example enalapril, lisinopril, ramipril), in particular if you have diabetes-related kidney problems.
aliskiren.
if you have had skin cancer or if you develop an unexpected skin lesion during the treatment.
Treatment with hydrochlorothiazide, particularly long term use with high doses, may increase the risk of some types of skin and lip cancer (non-melanoma skin cancer). Protect your skin
from sun exposure and UV rays while taking Irbesartan Hydrochlorothiazide Zentiva.
