Contents of the 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, causing blood vessels to relax, which in turn lowers blood pressure. Losartan reduces the worsening of kidney function in patients with high blood pressure and type 2 diabetes.
Losartan is used
Do not take losartan
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to take Losartan Stadafarma.
You must inform your doctor if you think you are pregnant (or might be). Losartan is not recommended at the beginning of pregnancy, and it should not be taken if you are pregnant for more than 3 months, as it may cause serious harm to your baby if used during this period (see section Pregnancy).
It is essential that you inform your doctor before taking losartan:
Your doctor may need to 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 Losartan Stadafarma”.
Consult your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking losartan. Your doctor will decide whether to continue treatment. Do not stop taking losartan on your own.
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 old, as it has not been shown to be effective in this age group.
Other medications and Losartan Stadafarma
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medications.
Inform your doctor if you are taking potassium supplements, salt substitutes that contain potassium, or potassium-sparing medications such as certain diuretics (amiloride, triamterene, spironolactone) or other medications that may increase serum potassium levels (e.g., heparin, trimethoprim-containing medications), as combination with losartan is not recommended.
While being treated with losartan, be particularly cautious if you take any of the following medications:
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 Stadafarma” and “Warnings and precautions”).
If your kidney function is impaired, concomitant use of these medications may lead to worsening of kidney function.
Medications containing lithium should not be taken in combination with losartan without close monitoring by your doctor. Special precautions may be necessary (e.g., blood tests).
Taking Losartan Stadafarma with food and drinks
Losartan can be taken with or without food.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
Pregnancy
You must inform your doctor if you think you are pregnant (or might be). Normally, your doctor will advise you to stop taking losartan before becoming pregnant or as soon as you know you are pregnant and will advise you to take another medication instead of losartan. Losartan is not recommended at the beginning of pregnancy, and it should not be taken if you are pregnant for more than 3 months, as it may cause serious harm to your baby if used from the third month of pregnancy.
Breastfeeding
Inform your doctor if you are breastfeeding or about to start breastfeeding. Losartan is not recommended for breastfeeding mothers, and your doctor may choose another treatment if you wish to continue breastfeeding. Especially if your child is a newborn or premature.
Driving and using machines
No studies have been conducted on the effects on the ability to drive and use machines.
It is unlikely that losartan will affect your ability to drive or use machines. However, like many medications 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.
Losartan Stadafarma contains lactose
This medication contains lactose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication.
Follow the instructions for administration of this medication exactly as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again. Your doctor will decide the appropriate dose of losartan, depending on your condition and whether you are taking other medications. It is essential to continue taking losartan as prescribed by your doctor to maintain constant blood pressure control.
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. Afterward, 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, inform your doctor or pharmacist.
Use in children and adolescents
Children under 6 years old
Losartan is not recommended for use in children under 6 years old, as it has not been shown to be effective in this age group.
Children between 6-18 years old
The recommended starting dose in patients who weigh between 20 and 50 kg is 0.7 mg of losartan per kg of body weight, administered 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 medication may be more suitable for children; ask your doctor or pharmacist.
Adult patients with high blood pressure and type 2 diabetes
Normally, treatment starts with 50 mg of losartan (one losartan 50 mg tablet) once a day. Afterward, the dose may be increased to 100 mg of losartan (two losartan 50 mg tablets or one losartan 100 mg tablet) once a day, depending on the response of your blood pressure.
Losartan can be administered with other medications that lower blood pressure (e.g., diuretics, calcium antagonists, alpha or beta blockers, and centrally acting medications), as well as with insulin and other medications 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) once a day can be used.
In the treatment of heart failure, losartan is normally combined with a diuretic (a medication that increases the amount of water that passes through your kidneys) and/or digitalis (a medication 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 old. Losartan is not recommended for use in patients with severe liver insufficiency (see section “Do not take Losartan Stadafarma”).
Administration
The tablets should be swallowed whole with a glass of water. You should try to take your daily dose at approximately the same time each day. It is essential to continue taking losartan as prescribed by your doctor.
The Losartan Stadafarma 50 mg tablet can be divided into equal doses.
