Contents of the pack and additional information

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

• Valsartánbelongs to a class of medications known as “angiotensin II receptor antagonists” that help control high blood pressure. Angiotensin II is a substance in the body that causes blood vessels to constrict, resulting in increased 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 Alter is used to treat high blood pressure that is not adequately controlled with the use of a single component.

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

Do not takeValsartán/Hidroclorotiazida Alter

• if you are allergic to valsartán, hidroclorotiazida, sulfonamide derivatives (chemical substances related to hidroclorotiazida) or any of the other components of this medication (listed in section 6)
• if you aremore than 3 months pregnant(in any case, it is better to avoid taking this medication also at the beginning of your pregnancy – see section “Pregnancy and breastfeeding”)
• if you have a severe liver diseaseorsmall bile duct destruction in the liver (biliary cirrhosis) that leads to bile accumulation in the liver (cholestasis)
• if you have a severe kidney disease
• if you are unable to produce urine (anuria)
• if you are undergoing dialysis
• if you have low levels of potassium or sodium in your blood, or if your blood calcium levels 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, inform your doctor and do not take this medication.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Valsartán/Hidroclorotiazida Alter:

• if you have had skin cancer or if you develop an unexpected skin lesion during treatment. The treatment with hidroclorotiazida, particularly long-term use at high doses, may increase the risk of certain types of skin cancer and lip cancer (non-melanoma skin cancer). Protect your skin from sun exposure and UV rays while taking Valsartán/Hidroclorotiazida Alter.
• if you have had respiratory or pulmonary problems (such as inflammation or fluid in the lungs) after taking hidroclorotiazida in the past. If you experience severe shortness of breath or difficulty breathing after taking Valsartán/Hidroclorotiazida Alter, seek medical attention immediately.
• if you are using potassium-sparing medications, potassium supplements, salt substitutes containing potassium, or other medications that increase blood potassium levels, such as heparin. Your doctor may consider regular monitoring of potassium levels
• if you have low levels of potassium in your blood
• if you experience severe diarrhea or vomiting
• if you are taking high doses of a diuretic
• if you have severe heart disease
• if you have heart failure or have had a heart attack. Follow your doctor's instructions carefully to start treatment. Your doctor may also monitor your renal function
• if you have renal artery stenosis
• if you have recently undergone a kidney transplant
• if you have primary aldosteronism, a disease in which the adrenal glands produce too much aldosterone hormone. In this case, valsartán/hidroclorotiazida is not recommended
• if you have kidney or liver disease
• if you have experienced swelling of the tongue and face caused by an allergic reaction called angioedema when taking other medications (including ACE inhibitors), inform your doctor. If you experience these symptoms when taking valsartán/hidroclorotiazida, stop taking it immediately and never take it again. See also section 4 “Possible side effects”
• if you have fever, skin rash, and joint pain, which may be signs of systemic lupus erythematosus (a known autoimmune disease)

• if you have previously experienced an allergic reaction with the use of another medication of this class to reduce blood pressure (angiotensin II receptor antagonists), or if you have any type of allergy or asthma
• if you experience vision loss or eye pain. These may be symptoms of fluid accumulation in the vitreous layer of the eye (choroidal effusion) or increased eye pressure, which can occur within a few hours to a week after taking valsartán/hidroclorotiazida. If left untreated, this can lead to permanent vision loss. You may be at higher risk of developing it if you have had an allergy to penicillin or sulfonamides in the past.
• if you are taking any of the following medications used to treat high blood pressure:
• • an angiotensin-converting enzyme inhibitor (ACE inhibitor) (such as enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes
  • aliskirén
