1. what losartan potassium is and what it is used for
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
- to treat patients with high blood pressure (hypertension)
- to protect the kidney in hypertensive type 2 diabetic patients with laboratory evidence of impaired renal function and proteinuria > 0.5 g per day (a condition in which urine contains an abnormal amount of protein).
- to treat patients with chronic heart failure when therapy with specific medicines called angiotensin-converting-enzyme inhibitors (ACE inhibitors, medicine used to lower high blood pressure) is not considered suitable by your doctor. If your heart failure has been stabilised with an ACE inhibitor you should not be switched to losartan.
- in patients with high blood pressure and a thickening of the left ventricle, Losartan potassium has been shown to decrease the risk of stroke (“LIFE indication”).
2. what you need to know before you take losartan potassium
Do not take Losartan potassium
- if you are allergic to losartan or any of the other ingredients of this medicine (listed in section 6)
- if your liver function is severely impaired
- if you are more than 3 months pregnant (it is also better to avoid losartan potassium in early pregnancy – see “Pregnancy and breast-feeding”)
- if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering medicine containing aliskiren
Warning and precautions
Talk to your doctor or pharmacist before taking Losartan potassium.
You must tell your doctor if you think 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:
- if you have had a history of angiooedema (swelling of the face, lips, throat, and/or tongue) (see also section 4 ‘Possible side effects’)
- if you suffer from excessive vomiting or diarrhoea leading to an extreme loss of fluid and/or salt in your body
- if you receive diuretics (medicines that increase the amount of water that you pass out through your kidneys) or are under dietary salt restriction leading to an extreme loss of fluid and salt in your body (see section 3 ‘Dosage in special patient groups’)
- if you are known to have narrowing or blockage of the blood vessels leading to your kidneys or if you have received a kidney transplant recently
- if your liver function is impaired (see sections 2 „Do not take Losartan“ and 3 ‘Dosage in special patient groups’)
- if you suffer from heart failure with or without renal impairment or concomitant severe life threatening cardiac arrhythmias. Special caution is necessary when you are treated with a B-blocker concomitantly
- if you have problems with your heart valves or heart muscle
- if you suffer from coronary heart disease (caused by a reduced blood flow in the blood vessels of the heart) or from cerebrovascular disease (caused by a reduced blood circulation in the brain)
- if you suffer from primary hyperaldosteronism (a syndrome associated with increased secretion of the hormone aldosterone by the adrenal gland, caused by an abnormality within the gland)
- if you are taking any of the following medicines used to treat high blood pressure:
-
- an ACE-inhibitor (for example enalapril, lisinopril, ramipril), in particular if you have diabetes-related kidney problems
-
- aliskiren
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”.
Children and adolescents
Losartan potassium has been studied in children. For more information, talk to your doctor.
Other medicines and Losartan potassium
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription or herbal medicines and natural products.
Take particular care if you are taking the following medicines while under treatment with Losartan potassium:
- other blood pressure lowering medicines as they may additionally reduce your blood pressure. Blood pressure may also be lowered by one of the following drugs/ class of drugs: tricyclic antidepressants, antipsychotics, baclofene, amifostine
- medicines which retain potassium or may increase potassium levels (e.g. potassium supplements, potassium-containing salt substitutes or potassium-sparing medicines such as certain diuretics [amiloride, triamteren, spironolactone] or heparin)
- non-steroidal anti-inflammatory drugs such as indometacin, including cox-2-inhibitors (medicines that reduce inflammation, and can be used to help relieve pain) as they may reduce the blood lowering effect of losartan
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 with food and drink
Losartan potassium may be taken with or without food.
Pregnancy and breast-feeding
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.
Driving and using machines
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.
Losartan potassium contains lactose
Losartan potassium contains lactose monohydrate. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.
3. how to take losartan potassium
Always take this medicine exactly as your doctor has told you. Check with your doctor 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.
Adult patients with High Blood Pressure Treatment usually starts with 50 mg losartan 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 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.
Use in children or adolescent (6 to 18 years old): The recommended dose in patients who weigh between 20 kg and 50 kg is 25 mg administered once a day. The doctor may increase the dose if blood pressure is not controlled.
The recommended dose in patients who weigh above 50 kg is 50 mg administered once a day. The doctor may increase the dose if blood pressure is not controlled
Adult patients with high blood pressure and type 2 diabetes
Treatment usually starts with 50 mg losartan once a day. The dose may later be increased to 100 mg losartan 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).
Patients with Heart Failure
Treatment usually starts with 12.5 mg losartan 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) up to the usual maintenance dose of 50 mg losartan once daily, according to your condition.
This medicine does not allow to take the 12.5 mg dose. In those cases in which losartan 12.5 mg is prescribed your doctor will have to choose another product.
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.
Dosage in special patient groups
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“).
Administration
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 take more Losartan potassium than you should
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.
If you forget to take Losartan potassium
If you accidentally miss a daily dose, just take the next dose as normal. Do not take a double dose to make up for a forgotten tablet. If you have any further questions on the use of this product, ask your doctor or pharmacist.
