Contents of the pack and additional information.

losartán/hidroclorotiazida cinfa is a combination of an angiotensin II receptor antagonist (losartán) and a diuretic (hidroclorotiazida). Angiotensin II is a substance produced in the body that binds to receptors present in blood vessels, causing them to constrict. This results in an increase in blood pressure. Losartán prevents the binding of angiotensin II to these receptors, causing blood vessels to relax, which in turn reduces blood pressure. Hidroclorotiazida causes the kidneys to eliminate a greater amount of water and salts. This also helps to reduce blood pressure.

losartán/hidroclorotiazida cinfa is indicated for the treatment of essential hypertension (high blood pressure).

Do not take losartán/hidroclorotiazida cinfa

• If you are allergic to losartán, hidroclorotiazida or any of the other components of this medicine (listed in section 6).
• If you are allergic to other sulfonamide-derived substances (for example, other thiazides, some antibacterial medicines such as cotrimoxazol, ask your doctor if you are unsure).
• If you have severe liver failure.
• If you have low levels of potassium or sodium, or high levels of calcium that cannot be corrected with treatment.
• If you have gout.
• If you are more than 3 months pregnant. (It is better to avoid losartán/hidroclorotiazida at the beginning of pregnancy – see Pregnancy section).
• If you have severe kidney failure or your kidneys do not produce urine.
• If you have diabetes or kidney failure and are being treated with a blood pressure-lowering medicine that contains aliskirén.

Warnings and precautions

Consult your doctor or pharmacist before starting to take losartán/hidroclorotiazida cinfa.

Consult your doctor if you experience abdominal pain, nausea, vomiting or diarrhea after taking losartán/hidroclorotiazida. Your doctor will decide whether to continue treatment. Do not stop taking losartán/hidroclorotiazida on your own.

If you experience a decrease in vision or eye pain, these may be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased eye pressure and may occur within a few hours to several weeks after taking losartán/hidroclorotiazida. If left untreated, this can lead to permanent vision loss. You may be at a higher risk of developing this if you have previously had an allergy to penicillin or sulfonamide.

You must inform your doctor if you think you may be pregnant (or could be). Losartán/hidroclorotiazida is not recommended for use at the beginning of pregnancy, and in any case, it should not be administered if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at this stage (see Pregnancy section).

It is essential to inform your doctor before taking losartán/hidroclorotiazida:

• If you have previously experienced swelling of the face, lips, tongue or throat;
• If you are taking diuretics (urine medicines);
• If you are following a low-sodium diet;
• If you have excessive vomiting and/or diarrhea;
• If you have heart failure;
• If your liver function is altered (see section 2 “Do not take losartán/hidroclorotiazida cinfa”);
• If you have narrowed arteries (arterial stenosis), if you only have one functioning kidney, or if you have recently undergone a kidney transplant;
• If you have atherosclerosis, angina pectoris (chest pain due to heart dysfunction);
• If you have aortic or mitral valve stenosis (narrowing of the heart valves) or hypertrophic cardiomyopathy (a disease that causes thickening of the heart valves);
• If you are diabetic;
• If you have had gout;
• If you have or have had an allergic reaction, asthma, or a disease that causes joint pain, skin eruptions, and fever (systemic lupus erythematosus);
• If you have high calcium levels or low potassium levels, or if you are following a low-potassium diet;
• If you need anesthesia (including dental anesthesia) or before surgery, or if you are undergoing tests to determine your parathyroid function, inform your doctor or healthcare professional that you are taking losartán potassium and hidroclorotiazida tablets;
• If you have primary aldosteronism (a syndrome associated with elevated aldosterone hormone secretion by the adrenal gland due to glandular alteration);
• If you are taking any of the following blood pressure-lowering medicines:

• An angiotensin-converting enzyme inhibitor (ACEI) (for example, enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes;
• Aliskirén.

• 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 losartán/hidroclorotiazida cinfa, seek medical attention immediately.

Your doctor may monitor your kidney function, blood pressure, and electrolyte levels (such as potassium) at regular intervals.

See also section 2“Do not take losartán/hidroclorotiazida cinfa”.

• If you are taking other medicines that may increase serum potassium levels (see section 2 “Other medicines and losartán/hidroclorotiazida cinfa”);
• If you have had skin cancer or if you develop an unexpected skin lesion during treatment. 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 losartán/hidroclorotiazida.

Children and adolescents

There is no experience with the use of losartán/hidroclorotiazida in children. Therefore, losartán/hidroclorotiazida should not be administered to children.

Other medicines and losartán/hidroclorotiazida cinfa

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medicine.

Inform your doctor if you are taking potassium supplements, salt substitutes containing potassium, potassium-sparing medicines, or other medicines that may increase serum potassium levels (e.g., trimetoprim-containing medicines), as the combination with losartán/hidroclorotiazida is not recommended.

Diuretics like hidroclorotiazida in losartán/hidroclorotiazida may interact with other medicines.

Lithium preparations should not be taken with losartán/hidroclorotiazida without your doctor's close monitoring.

You may need to take special precautions (e.g., blood tests) if you are taking other diuretics (urine tablets), some laxatives, gout medicines, heart rhythm control medicines, or diabetes medicines (oral or insulin).

It is also essential that your doctor knows if you are taking:

• Other blood pressure-lowering medicines,
• Steroids,
• Cancer medicines,
• Pain medicines,
• Fungal infection medicines,
• Arthritis medicines,
• Cholesterol-lowering resins like colestiramina,
• Muscle relaxants,
• Sleeping tablets;
• Opioid medicines like morphine,
• "pressor amines" like adrenaline or other medicines in the same group,
• Oral diabetes or insulin medicines.

Your doctor may need to adjust your dose and/or take other precautions:

If you are taking an ACEI or aliskirén (see also sections“Do not take losartán/hidroclorotiazida cinfa”and“Warnings and precautions”).

When taking losartán/hidroclorotiazida, inform your doctor if you are to undergo a radiographic examination with a contrast medium containing iodine.

Taking losartán/hidroclorotiazida cinfa with food, drinks, and alcohol

Excessive salt in the diet may counteract the effect of losartán/hidroclorotiazida tablets.

Losartán/hidroclorotiazida can be taken with or without food.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, or think you may be pregnant (or could be), consult your doctor or pharmacist before using this medicine.

Pregnancy

Losartán/hidroclorotiazida is not recommended for use at the beginning of pregnancy, and in any case, it should not be administered after the third month of pregnancy, as it may cause serious harm to your baby if used at this stage.
