1. What Losartán/Hidroclorotiazida Normon is and what it is used for
Losartán/Hidroclorotiazida Normon 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 leads to an increase in 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 more 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 Normon
Do not take Losartán/Hidroclorotiazida Normon
- If you are allergic to losartan, hydrochlorothiazide, or any of the other components 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 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 (losartan/hydrochlorothiazide should also be avoided early in pregnancy; see Pregnancy section).
- If you have severe renal 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 containing aliskiren.
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before starting this medicine.
If you experience vision changes 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 weeks after taking losartan/hydrochlorothiazide. If left untreated, this may lead to permanent vision loss. Your risk may be higher if you previously had an allergy to penicillin or sulfonamides.
You must inform your doctor if you think you are pregnant (or could 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 your baby if used at this stage (see Pregnancy section).
It is important to inform your doctor before taking this medicine:
- 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 difficulty breathing after taking losartan/hydrochlorothiazide, seek medical attention immediately.
- If you have previously experienced swelling of the face, lips, tongue, or throat.
- If you are taking diuretics ("water pills").
- 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 Normon”).
- If you have narrowed arteries supplying the kidneys (renal artery stenosis), only one functioning kidney, or have recently undergone a kidney transplant.
- If you have narrowed arteries (atherosclerosis), angina (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 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 before surgery, or if you are undergoing tests to assess parathyroid function, inform your doctor or healthcare provider that you are taking losartan potassium and hydrochlorothiazide tablets.
- If you have primary hyperaldosteronism (a syndrome associated with excessive aldosterone hormone secretion from the adrenal gland due to adrenal dysfunction).
- If you are taking any of the following medicines for high blood pressure:
- An angiotensin-converting enzyme (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 Normon."
- If you are taking other medicines that may increase serum potassium (see section 2 “Other medicines and Losartán/Hidroclorotiazida Normon”).
- 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 and lip cancers. Protect your skin from sun exposure and UV radiation while taking losartan/hydrochlorothiazide.
Consult your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking this medicine. Your doctor will decide whether to continue treatment. Do not stop taking this medicine on your own.
Children and adolescents
There is no experience with the use of losartan/hydrochlorothiazide in children. Therefore, losartan/hydrochlorothiazide should not be given to children.
Other medicines and Losartán/Hidroclorotiazida Normon
Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.
Inform 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 losartan/hydrochlorothiazide may interact with other medicines.
Lithium-containing preparations should not be taken with losartan/hydrochlorothiazide unless your doctor closely monitors you.
Special precautions (e.g., blood tests) may be necessary if you are taking other diuretics ("water pills"), certain laxatives, gout treatments, medicines to control heart rhythm, or diabetes medicines (oral agents or insulin).
