1. What Losazid is and what it is used for

Losazid contains the active substances losartan potassium and hydrochlorothiazide.
Losartan belongs to a group of medicines known as angiotensin II receptor antagonists, and
hydrochlorothiazide is a diuretic.
Losazid works by dilating blood vessels, thereby lowering blood pressure.
Hydrochlorothiazide works by increasing the elimination of water and salts through the kidneys, thus helping to reduce blood pressure.
Losazid is indicated for the treatment of high blood pressure (essential hypertension) in patients whose blood pressure is not adequately controlled with losartan or hydrochlorothiazide alone.

2. What you need to know before taking Losazid

Do not take Losazid

  • 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 co-trimoxazole; ask your doctor if you are unsure)
  • if you have severe impairment of liver function (cholestasis and obstructive biliary disorders)
  • if you have low potassium levels, low sodium levels, or high calcium levels that cannot be corrected with specific treatment
  • if you have gout
  • if you are pregnant (see section “Pregnancy and breastfeeding”)
  • if you have severe impairment of kidney function
  • if you are not passing urine
  • if you have diabetes or impaired kidney function and are being treated with a blood pressure-lowering medicine containing aliskiren.

Warnings and precautions
Talk to your doctor or pharmacist before taking Losazid. Contact your doctor if, after taking
Losazid, you experience abdominal pain, nausea, vomiting, or diarrhoea. Your doctor will decide whether
treatment should continue. Do not stop taking Losazid on your own.
Inform your doctor before taking Losazid:

  • if you have previously had swelling of the face, lips, throat, and/or tongue (angioedema)
  • if you are taking other medicines or supplements that retain potassium or may increase potassium levels (see section “Other medicines and Losazid”):
    o diuretics (medicines that increase the amount of water and salts excreted by the kidneys), particularly potassium-sparing diuretics, or potassium supplements, or potassium-containing salt substitutes
  • if you are on a low-sodium diet
  • if you have had or currently have severe, recurrent vomiting and/or diarrhoea
  • if you have or have had liver problems (see section 2 “Do not take Losazid”)
  • if you have or have had impaired kidney function (see section 2 “Do not take Losazid”)
  • if you have narrowing or blockage of blood vessels supplying the kidneys (bilateral renal artery stenosis or stenosis of the artery to a single kidney)
  • if you have recently undergone a kidney transplant
  • if you have heart failure
  • if you have a condition caused by reduced blood flow in the blood vessels of the heart (cardiovascular ischemic disease) or a condition caused by reduced blood circulation in the brain (cerebrovascular disease)
  • if you have narrowing of heart valves (mitral or aortic valve stenosis) or a condition causing thickening of the heart muscle (hypertrophic cardiomyopathy)
  • if you have diabetes, as your diabetes medication doses may need adjustment
  • if you have or have had an allergic condition, asthma, or a condition causing joint pain, skin redness, and fever (systemic lupus erythematosus)
  • if you have a syndrome associated with increased secretion of the hormone aldosterone (primary hyperaldosteronism)
  • if you are taking other medicines that may increase serum potassium levels (see section 2 “Other medicines and Losazid”)
  • if you have previously 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 sun exposure and UV radiation while taking Losazid.
  • 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 eye pressure, which may occur within hours or weeks after starting Losazid. If not treated promptly, this condition may lead to permanent vision loss. If you are allergic to penicillin or sulfonamides, you may have a higher risk of developing choroidal effusion.
  • if you are taking any of the following medicines for high blood pressure:
    o an ACE inhibitor (e.g. enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes, or aliskiren.

Inform your doctor during treatment with Losazid:

  • if you are scheduled for a test to evaluate parathyroid function, as treatment with Losazid must be stopped before this test
  • if you develop allergic reactions, which may manifest as swelling of the face, lips, mouth, or throat.

Your doctor may monitor your kidney function, blood pressure, electrolyte levels (e.g. potassium), and blood levels of triglycerides and cholesterol at regular intervals.
See also the information under “Do not take Losazid.”
If you are of Black ethnicity, it is important to know that medicines such as losartan may be less effective in reducing blood pressure.

Children and adolescents
Do not give Losazid to children and adolescents.
