1. What Losartán/Hidroclorotiazida Viatis is and what it is used for

Losartán/Hidroclorotiazida Viatris is a combination of an angiotensin II receptor antagonist (losartan) and a diuretic (hydrochlorothiazide).

Angiotensin II is a substance produced in the body that binds to receptors located in blood vessels, causing them to narrow. This leads to an increase in blood pressure.

Losartan prevents angiotensin II from binding to these receptors, resulting in relaxation of the blood vessels, thereby lowering blood pressure.

Hydrochlorothiazide causes the kidneys to eliminate increased amounts of water and salts. This also helps reduce blood pressure.

Losartan/hydrochlorothiazide is indicated for the treatment of essential hypertension (high blood pressure).

2. What you need to know before taking Losartan/Hydrochlorothiazide Viatris

Do not take Losartan/Hydrochlorothiazide Viatris

• If you are allergic to losartan, hydrochlorothiazide, or any of the other ingredients of this medicine (listed in section 6).
• If you are allergic to other sulfonamide-derived substances (e.g., other thiazides, certain antibacterial agents such as cotrimoxazole; ask your doctor if you are unsure).
• If you are more than 3 months pregnant (it is also preferable to avoid losartan/hydrochlorothiazide during the first months of pregnancy – see Pregnancy section).
• If you have severe liver impairment.
• If you have severe renal impairment or your kidneys are not producing urine.
• 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 have diabetes or renal impairment and are being treated with a blood pressure-lowering medicine containing aliskiren.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before taking Losartan/Hydrochlorothiazide Viatris.

It is important that you inform your doctor before taking losartan/hydrochlorothiazide:

• If you have previously experienced swelling of the face, lips, tongue, or throat.
• If you are taking diuretics (medicines to increase urine production).
• If you are on a low-salt diet.
• If you have had excessive vomiting and/or diarrhea.
• If you have heart failure.
• If you have narrowing of the arteries supplying the kidneys (renal artery stenosis), only one functioning kidney, or have recently undergone a kidney transplant.
• If you have narrowing of the arteries (atherosclerosis), angina pectoris (chest pain due to poor heart function).
• If you have aortic or mitral valve stenosis (narrowing of the heart valves) or hypertrophic cardiomyopathy (a condition causing thickening of the heart muscle).
• If you have diabetes.
• If you have had gout.
• If you have or have had an allergic disorder, asthma, or a condition causing joint pain, skin rashes, and fever (systemic lupus erythematosus).
• If you have high calcium levels or low potassium levels, or if you are on a low-potassium diet.
• If you require anesthesia (including at the dentist) or prior to surgery, or if you are undergoing tests to assess parathyroid function, you must inform the doctor or healthcare professional that you are taking losartan potassium and hydrochlorothiazide tablets.
• If you have primary hyperaldosteronism (a syndrome associated with excessive aldosterone hormone secretion by the adrenal gland due to dysfunction of this gland).
• If you are taking any of the following medicines used to treat high blood pressure (hypertension):
• An angiotensin-converting enzyme inhibitor (ACE inhibitor) (e.g., enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes.
• Aliskiren.

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

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

• 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 exposure to sunlight and UV rays while taking losartan/hydrochlorothiazide.
• If you are taking other medicines that may increase serum potassium (see section 2 “Other medicines and Losartan/Hydrochlorothiazide Viatris”);
• If you experience vision loss or eye pain. These could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased intraocular pressure, which may occur within hours to a week after taking losartan/hydrochlorothiazide. This may lead to permanent vision impairment if not treated.
• If you have previously experienced respiratory or pulmonary problems (such as inflammation or fluid in the lungs) after taking hydrochlorothiazide. If you develop severe shortness of breath or difficulty breathing after taking losartan/hydrochlorothiazide, seek medical attention immediately.
