Contents of the package leaflet
Losartan belongs to a group of medicines called angiotensin II receptor antagonists. 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, which causes the blood vessels to relax, thereby lowering blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.
Potassium losartan is used

Children and adolescents
Losartan has been studied in children. For more information, talk to your doctor.
Losartan is not recommended for use in children with kidney or liver problems, as there is limited data available in these patient groups. Losartan is not recommended for use in children under 6 years of age, as it has not been shown to work in this age group.
Taking losartan with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Tell your doctor if you are taking potassium supplements, salt substitutes that contain potassium, or potassium-sparing medicines such as certain diuretics (amiloride, triamterene, spironolactone) or other medicines that may increase serum potassium levels (e.g., heparin, trimethoprim-containing medicines), as combination with losartan is not recommended.
While you are being treated with losartan, be particularly careful if you take any of the following medicines:
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 the information under the headings “Do not take Losartan Tarbis Farma” and “Warnings and precautions”).
If your kidney function is impaired, concomitant use of these medicines may lead to worsening of kidney function.
Medicines that contain lithium should not be taken in combination with losartan without close supervision by your doctor. Special precautions may be necessary (e.g., blood tests).
Taking losartan with food and drinks
Losartan can be taken with or without food.
Pregnancy and breastfeeding
Pregnancy
You must tell your doctor if you think you are pregnant (or might be). Normally, your doctor will advise you to stop taking losartan before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of losartan. Losartan is not recommended at the beginning of pregnancy, and it must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used from the third month of pregnancy.
Breastfeeding
Tell your doctor if you are breastfeeding or about to start breastfeeding. Losartan is not recommended for mothers who are breastfeeding, and your doctor may choose another treatment if you wish to continue breastfeeding. Especially if your child is a newborn or was born prematurely.
Consult your doctor or pharmacist before using this medicine.
Driving and using machines
No studies have been performed on the effects on the ability to drive and use machines.
Losartan is unlikely to affect your ability to drive or use machines. However, as with many medicines used to treat high blood pressure, losartan may cause dizziness or drowsiness in some people. If you experience dizziness or drowsiness, consult your doctor before performing these activities.

Your doctor will decide the appropriate dose of losartan, depending on your condition and whether you are taking other medicines. It is important to keep taking losartan while your doctor prescribes it to you to maintain constant control of your blood pressure.
Adult patients with high blood pressure
Normally, treatment starts with 50 mg of losartan (one losartan 50 mg tablet) once a day. The maximum blood pressure-lowering effect should be achieved within 3-6 weeks of starting treatment. After that, in some patients, the dose may be increased to 100 mg of losartan (two losartan 50 mg tablets or one losartan 100 mg tablet) once a day.
If you think the effect of losartan is too strong or too weak, tell your doctor or pharmacist.

Children aged 6-18 years
The recommended starting dose in patients who weigh between 20 and 50 kg is 0.7 mg of losartan per kg of body weight, given once a day (up to 25 mg of losartan). The doctor may increase the dose if blood pressure is not controlled.
Other pharmaceutical forms of this medicine may be more suitable for children; ask your doctor or pharmacist.
Adult patients with high blood pressure and type 2 diabetes

Losartan can be given with other medicines that lower blood pressure (e.g., diuretics, calcium antagonists, alpha or beta blockers, and centrally acting agents), as well as with insulin and other medicines frequently used to lower blood glucose levels (e.g., sulfonylureas, glitazones, and glucosidase inhibitors).
Adult patients with heart failure
Normally, treatment starts with 12.5 mg of losartan (one losartan 12.5 mg tablet) once a day. Normally, the dose should be gradually increased, weekly (i.e., 12.5 mg per day during the first week, 25 mg per day during the second week, 50 mg per day during the third week, 100 mg per day during the fourth week, 150 mg per day during the fifth week), up to a maintenance dose determined by your doctor. A maximum dose of 150 mg of losartan (e.g., three losartan 50 mg tablets or one losartan 100 mg tablet and one losartan 50 mg tablet) can be used once a day.
In the treatment of heart failure, losartan is normally combined with a diuretic (a medicine that increases the amount of water that passes through your kidneys) and/or digitalis (a medicine that helps your heart be stronger and more efficient) and/or a beta-blocker.
Posology in special patient groups
Your doctor may recommend a lower dose, especially when starting treatment in certain patients, such as those treated with high-dose diuretics, patients with liver insufficiency, or patients over 75 years of age. Losartan is not recommended for use in patients with severe liver insufficiency (see section “Do not take losartan”).
