Valsartan/Hydrochlorothiazide TecniGen 160mg/25mg Film-Coated Tablets

Read this package insert carefully before starting to take this medication, as it contains important information for you.

• Keep this package insert, as you may need to refer to it again.
• If you have any questions, consult your doctor, pharmacist, or nurse.
• This medication has been prescribed only for you and should not be given to others, even if they have the same symptoms as you, as it may harm them.
• If you experience any adverse effects, consult your doctor or pharmacist or nurse, even if they are not listed in this package insert. See section 4.

Valsartán/Hidroclorotiazida TecniGen film-coated tablets contain two active ingredients known as valsartán and hidroclorotiazida. These components help to control high blood pressure (hypertension).

• Valsartánbelongs to a class of medications known as “angiotensin II receptor antagonists” that help to control high blood pressure. Angiotensin II is a substance in the body that causes blood vessels to constrict, resulting in an increase in blood pressure. Valsartán acts by blocking the effect of angiotensin II. As a result, blood vessels relax and blood pressure decreases.
• Hidroclorotiazidabelongs to a class of medications known as thiazide diuretics. Hidroclorotiazida increases diuresis, which also decreases blood pressure.

Valsartán/Hidroclorotiazida TecniGen is used to treat high blood pressure that is not adequately controlled with the use of a single component.

Hypertension increases the workload of the heart and arteries. If left untreated, it can damage blood vessels in the brain, heart, and kidneys and may cause a stroke, heart failure, or kidney failure. High blood pressure increases the risk of heart attacks. Reducing blood pressure to normal values reduces the risk of developing these disorders.

Do not take Valsartán/Hidroclorotiazida TecniGen

• If you are allergic to valsartan, hidroclorotiazida, sulfonamide derivatives (chemicals related to hidroclorotiazida) or any other component of this medication (listed in section 6).
• If you are more than 3 months pregnant.(In any case, it is better to avoid taking this medication also at the beginning of your pregnancy – see Pregnancy section).
• If you have a severe liver disease.
• If you have a severe kidney disease.
• If you cannot urinate.
• If you are undergoing dialysis.
• If you have low levels of potassium or sodium in your blood, or if your calcium levels in the blood are higher than normal despite treatment.
• If you have gout.
• If you have diabetes or kidney insufficiency and are being treated with a medication to reduce blood pressure that contains aliskirén..

If any of these situations affect you, do not take this medication and consult your doctor.
