1. What is Losartan Hydrochlorothiazide Krka and what is it used for

Losartan Hydrochlorothiazide Krka 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 in blood vessels, causing them to narrow. This leads to an increase in blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to widen and blood pressure to decrease. Hydrochlorothiazide works by increasing the amount of water and salt excreted in the urine. This also helps to lower blood pressure. Losartan Hydrochlorothiazide Krka is indicated for the treatment of primary hypertension (high blood pressure).

2. Important information before taking Losartan Hydrochlorothiazide Krka

When not to take Losartan Hydrochlorothiazide Krka:

  • if you are allergic to losartan and/or 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 thiazide diuretics, certain antibacterial drugs such as cotrimoxazole - if in doubt, consult your doctor),
  • if you have severe liver function disorders,
  • if you have low potassium, low sodium or high calcium levels in your blood that cannot be corrected by treatment,
  • if you have gout,
  • if you are pregnant more than three months (you should also avoid taking Losartan Hydrochlorothiazide Krka in early pregnancy - see section "Pregnancy and breastfeeding"),
  • if you have severe kidney function disorders or if your kidneys do not produce urine,
  • if you have diabetes or kidney function disorders and are being treated with a blood pressure-lowering medicine containing aliskiren.
