Losartan belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body which binds to receptors in blood vessels, causing them to tighten. This results in an increase in blood pressure. Losartan prevents the binding of angiotensin-II to these receptors, causing the blood vessels to relax which in turn lowers the blood pressure. Losartan slows the decrease of kidney function in patients with high blood pressure and type 2 diabetes.
Losartan potassium is used
Talk to your doctor or pharmacist before taking Losartan potassium.
You must tell your doctor if you think that you are (or might become) pregnant. Losartan potassium is not recommended in early pregnancy, and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to your baby if used at that stage (see pregnancy section).
It is important to tell your doctor before taking Losartan potassium:
Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g. potassium) in your blood at regular intervals.
See also information under the heading “Do not take Losartan potassium”
Losartan has been studied in children. For more information, talk to your doctor.
Losartan is not recommended for use in children suffering from kidney or liver problems, as limited data are available in these patient groups. Losartan is not recommended for use in children under 6 years old, as it has not been shown to work in this age group.
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, potassium-containing salt substitutes, potassium-sparing medicines such as certain diuretics (e.g., amiloride, triamteren, spironolactone), or other medicines that may increase serum potassium (e.g., heparin, trimethoprim-containing medicines), as the combination with Losartan potassium is not advisable.
Take particular care if you are taking the following medicines while under treatment with Losartan potassium:
If your kidney function is impaired, the concomitant use of these medicines may lead to a worsening of the kidney function.
Lithium containing medicines should not be taken in combination with losartan without close supervision by your doctor. Special precautionary measures (e.g. blood tests) may be appropriate.
Your doctor may need to change your dose and/or to take other precautions:
If you are taking an ACE-inhibitor or aliskiren (see also information under the headings “Do not take Losartan potassium” and “Warnings and precautions”)
Losartan potassium may be taken with or without food.
Ask your doctor or pharmacist for advice before taking any medicine.
Pregnancy
You must tell your doctor if you think you are (or might become) pregnant. Your doctor will normally advise you to stop taking Losartan potassium before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Losartan potassium. Losartan potassium is not recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as it may cause serious harm to your baby if used after the third month of pregnancy.
Breastfeeding
Tell your doctor if you are breast-feeding or about to start breast-feeding. Losartan potassium is not recommended for mothers who are breast-feeding, and your doctor may choose another treatment for you if you wish to breast-feed, especially if your baby is newborn, or was born prematurely.
No studies on the effects on the ability to drive and use machines have been performed.
Losartan potassium is unlikely to affect your ability to drive or use machines. However, as with many other medicines used to treat high blood pressure, losartan may cause dizziness or drowsiness in some people. If you experience dizziness or drowsiness, you should consult your doctor before attempting such activities.
If you have been told by your doctor that you have intolerance to some sugars, contact your doctor before taking this medicinal product.
Always take this medicine exactly as described in this leaflet or as your doctor or pharmacist have told you. Check with your doctor or pharmacist if you are not sure. Your doctor will decide on the appropriate dose of Losartan potassium, depending on your condition and whether you are taking other medicines. It is important to continue taking Losartan potassium for as long as your doctor prescribes it in order to maintain smooth control of your blood pressure.
Losartan potassium containing medicinal products are available in the following strengths: 12.5 mg, 25 mg, 50 mg and 100 mg.
Adult patients with high blood pressure
Treatment usually starts with 50 mg losartan (one tablet Losartan potassium 50 mg) once a day. The maximal blood pressure lowering effect should be reached 3-6 weeks after beginning treatment. In some patients the dose may later be increased to 100 mg losartan (two tablets Losartan potassium 50 mg or one tablet of Losartan potassium 100 mg) once daily.
If you have the impression that the effect of losartan is too strong or too weak, please talk to your doctor or pharmacist.
Children below 6 years of age
Losartan potassium is not recommended for use in children under 6 years old, as it has not been shown to work in this age group.
Children aged 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 potassium). The doctor may increase the dose if blood pressure is not controlled.
Other form(s) of this medicine may be more suitable for children; ask your doctor or pharmacist.
Adult patients with high blood pressure and type 2 diabetes
Treatment usually starts with 50 mg losartan (one tablet Losartan potassium 50 mg) once a day. The dose may later be increased to 100 mg losartan (two tablets Losartan potassium 50 mg or one tablet of Losartan potassium 100 mg) once daily depending on your blood pressure response.
Losartan tablets may be administered with other blood pressure lowering medicines (e.g. diuretics, calcium channel blockers, alpha- or beta-blockers, and centrally acting agents) as well as with insulin and other commonly used medicines that decrease the level of glucose in the blood (e.g. sulfonylureas, glitazones and glucosidase inhibitors).
Adult patients with heart failure
Treatment usually starts with 12.5 mg losartan (one tablet Losartan potassium 12.5 mg) once a day. Generally, the dose should be increased weekly step-by-step (i.e., 12.5 mg daily during the first week, 25 mg daily during the second week, 50 mg daily during the third week, 100 mg daily during the fourth week, 150 mg daily during the fifth week) up to the maintenance dose as determined by your physician. A maximum dose of 150 mg losartan (for example, three tablets of Losartan potassium 50 mg or one tablet each of Losartan potassium 100 mg and Losartan potassium 50 mg) once daily may be used.
In the treatment of heart failure, losartan is usually combined with a diuretic (medicine that increases the amount of water that you pass out through your kidneys) and/or digitalis (medicine that helps to make the heart stronger and more efficient) and/or a beta-blocker.
The doctor may advise a lower dose, especially when starting treatment in certain patients such as those treated with diuretics in high doses, in patients with liver impairment, or in patients over the age of 75 years. The use of losartan is not recommended in patients with severe hepatic impairment (see section "Do not take Losartan potassium").
The tablets should be swallowed with a glass of water. You should try to take your daily dose at about the same time each day. It is important that you continue to take Losartan potassium until your doctor tells you otherwise.
If you accidentally take too many tablets, or a child swallows some, contact your doctor immediately. Symptoms of overdose are low blood pressure, increased heartbeat, possibly decreased heartbeat.
Do not take a double dose to make up for a forgotten dose.
If you accidentally miss a daily dose, just take the next dose as normal.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
