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

Losartán/hidroclorotiazida 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 in the blood vessels, causing them to narrow. This results in increased blood pressure. Losartán prevents angiotensin II from binding to these receptors, allowing blood vessels to relax, thereby lowering blood pressure. Hidroclorotiazida causes the kidneys to eliminate increased amounts of water and salts, which also helps reduce blood pressure.

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

2. What you need to know before taking Losartán/Hidroclorotiazida Stada

Do not take Losartán/Hidroclorotiazida Stada

• 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 medicines such as cotrimoxazole; ask your doctor if you are unsure),
• if you have severe liver impairment,
• 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 (Losartan/hydrochlorothiazide should also be avoided in early pregnancy – see Pregnancy section),
• if you have severe renal impairment or your kidneys are not producing urine,
• if you have diabetes or kidney disease and are being treated with an antihypertensive medicine containing aliskiren.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Losartán/Hidroclorotiazida Stada.

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

Inform your doctor if you are pregnant (or suspect you might be). Losartan/hydrochlorothiazide is not recommended during early pregnancy and must not be taken after the third month of pregnancy, as it may cause serious harm to the unborn baby from that stage onward (see Pregnancy section).

It is important to inform your doctor before taking Losartán/Hidroclorotiazida Stada:

• if you have previously had swelling of the face, lips, tongue, or throat,

• if you are taking diuretics (medicines to increase urine output),

• if you are on a low-salt diet,

• if you have or have had excessive vomiting and/or diarrhea,

• if you have heart failure,

• if your liver function is impaired (see section 2 “Do not take Losartán/Hidroclorotiazida Stada”),

• if you have narrowing of the arteries leading to the kidneys (renal artery stenosis), only one functioning kidney, or have recently undergone a kidney transplant,

• if you have arterial narrowing (atherosclerosis), angina pectoris (chest pain due to poor heart function),

• if you have aortic or mitral valve stenosis (narrowing of heart valves) or hypertrophic cardiomyopathy (a condition causing thickening of the heart muscle),

• if you are diabetic,

• if you have had gout,

• if you have or have had an allergic disorder, asthma, or a disease causing joint pain, skin rash, 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 before surgery, or if you are undergoing tests to assess parathyroid function, you must inform the doctor or healthcare staff that you are taking losartan potassium and hydrochlorothiazide tablets,

• if you have primary hyperaldosteronism (a syndrome associated with excessive secretion of the hormone aldosterone by the adrenal gland due to adrenal dysfunction).

• 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.

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

See also the information under the heading “Do not take Losartán/Hidroclorotiazida Stada”.

• if you are taking other medicines that may increase serum potassium (see section 2 “Other medicines and Losartán/Hidroclorotiazida Stada”).

• if you experience vision loss or eye pain, which could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased intraocular pressure, occurring within hours to weeks after taking losartan/hydrochlorothiazide. This may lead to permanent vision loss if untreated. Your risk may be higher if you previously had an allergy to penicillin or sulfonamides.

• if you have had skin cancer or develop an unexpected skin lesion during treatment. Treatment with hydrochlorothiazide, especially long-term use at high doses, may increase the risk of certain types of non-melanoma skin and lip cancer. Protect your skin from sun and UV exposure while taking losartan/hydrochlorothiazide.

• if you have had respiratory or lung problems (such as inflammation or fluid in the lungs) after taking hydrochlorothiazide in the past. If you develop shortness of breath or severe breathing difficulty after taking losartan/hydrochlorothiazide, seek medical attention immediately.

Children and adolescents

There is no experience with the use of losartan/hydrochlorothiazide in children. Therefore, losartan/hydrochlorothiazida should not be given to children.

Other medicines and Losartán/Hidroclorotiazida Stada

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

Tell your doctor if you are taking potassium supplements, salt substitutes containing potassium, potassium-sparing medicines, or other medicines that may increase serum potassium (e.g. medicines containing trimethoprim), as combination with losartan/hydrochlorothiazide is not recommended.

Diuretics such as hydrochlorothiazide contained in Losartán/Hidroclorotiazida Stada may interact with other medicines.

Lithium-containing preparations should not be taken with losartan/hydrochlorothiazide unless your doctor performs careful monitoring.

Special precautionary measures (e.g. blood tests) may be appropriate if you are taking other diuretics (water tablets), certain laxatives, gout medications, medicines to control heart rhythm, or diabetes medicines (oral agents or insulin).

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

• other medicines to lower your blood pressure,
• steroids,
• cancer treatment medicines,
• pain medicines,
• antifungal medicines,
• arthritis medicines,
• cholesterol-lowering resins such as cholestyramine,
• muscle relaxants,
• sleeping tablets,
• opioid medicines such as morphine,
• "pressor amines" such as adrenaline or other medicines in the same group,
• oral diabetes medicines or insulin.

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

If you are taking an angiotensin-converting enzyme inhibitor (ACE inhibitor) or aliskiren (see also information under the headings “Do not take Losartán/Hidroclorotiazida Stada” and “Warnings and precautions”).

Please inform your doctor if you are planning to undergo iodinated contrast media procedures while taking losartan/hydrochlorothiazide.

Taking Losartán/Hidroclorotiazida Stada with food, drinks, and alcohol
