1. What Candesartán/Hidroclorotiazida Alter is and what it is used for

Your medicine is called Candesartán/Hidroclorotiazida Alter. It is used to treat high blood pressure (hypertension). It contains two active substances: candesartan cilexetil and hydrochlorothiazide. Both work together to lower blood pressure.

• Candesartan cilexetil belongs to a group of medicines called angiotensin II receptor antagonists. It helps blood vessels to relax and widen, making it easier to reduce blood pressure.
• Hydrochlorothiazide belongs to a group of medicines called diuretics. It helps the body get rid of water and salts such as sodium through the urine. This also helps reduce blood pressure.

Your doctor may prescribe Candesartán/Hidroclorotiazida Alter if your blood pressure has not been adequately controlled with candesartan cilexetil or hydrochlorothiazide alone.

2. What you need to know before taking Candesartan/Hydrochlorothiazide Alter

• if you are allergic to sulfonamides. If you are unsure whether this applies to you, consult your doctor.
• if you are more than 3 months pregnant. (It is also advisable to avoid candesartan/hydrochlorothiazide during the first months of pregnancy – see Pregnancy section).
• if you have severe kidney disease.
• if you have severe liver disease or biliary obstruction (a problem with bile drainage from the gallbladder).

Warnings and precautions

Talk to your doctor or pharmacist before taking Candesartan/Hydrochlorothiazide Alter

• If you have had skin cancer or develop an unexpected skin lesion during treatment. Treatment with hydrochlorothiazide, particularly long-term use at high doses, may increase the risk of certain types of non-melanoma skin cancer and lip cancer. Protect your skin from sun exposure and UV radiation while taking Candesartan/Hydrochlorothiazide Alter.
• If you experience vision changes or eye pain, which could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased intraocular pressure. These may occur within hours to a week after taking candesartan/hydrochlorothiazide.
• If you have previously experienced respiratory or lung problems (such as inflammation or fluid in the lungs) after taking hydrochlorothiazide. If you develop shortness of breath or severe difficulty breathing after taking Candesartan/Hydrochlorothiazide Alter, seek medical attention immediately.
