Dosage Reference

Reference Information Only

Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.

Adults:

The usual starting and maintenance dose for most patients is 50 mg once daily. If 50 mg once daily does not lower blood pressure enough, 25 mg twice daily is recommended before the dose is increased. For patients with intravascular volume depletion (for example, those treated with high-dose diuretics), a starting dose of 25 mg once daily should be considered. Losartan Potassium can be given once or twice daily. The total daily dose ranges from 25 mg to 100 mg. Patients up to 75 years: No initial dosage adjustment is necessary for this group of patients. Patients over 75 years: There is currently limited clinical experience in this group; a lower starting dose of 25 mg once daily is recommended.

Side Effects

Side effects of Losart-P are generally mild and short-lived. The most common are dizziness, diarrhoea, nasal congestion, cough and upper respiratory tract infection. Less common side effects include fatigue, oedema (swelling), abdominal pain, chest pain, nausea, headache and pharyngitis (sore throat).

Cautions & Contraindications

Warnings & Precautions

If Losart-P is used in the second and third trimesters of pregnancy, it reduces the baby's kidney function and raises the risk of illness and death in the fetus and the newborn. In patients who are low in body fluid volume, for example those on high-dose diuretics, symptomatic hypotension may occur. The plasma concentration of Losart-P is much higher in patients with cirrhosis. Changes in kidney function, including renal failure, have been reported in patients who already have impaired kidney function.

Contraindications

Losartan Potassium must not be used during pregnancy, or in anyone who is hypersensitive (allergic) to losartan or to any other ingredient of this product. It also must not be given together with aliskiren to patients who have diabetes.
