What Losartan is used for
Losartan is used
• to treat patients with high blood pressure (hypertension) in adults and in children and adolescents 6 - 18 years of age.
• 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.

How to take Losartan
Adult patients with High Blood Pressure
Treatment usually starts with 50 mg losartan (one tablet Losartan 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 50 mg) once daily.
Use in children and adolescents
Children below 6 years of age
Losartan 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. The doctor may increase the dose if blood pressure is not controlled.
The tablets should be swallowed whole 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 until your doctor tells you otherwise.
