How to take losartan

Losartan tablets can be taken with or without food and should be swallowed whole with a drink of water. You should aim to take your tablet at the same time every day. If you forget to take a dose, please skip the missed tablet and continue with the next tablet at your usual time. Please do not take two tablets on the same day to make up for the dose you missed.


Each losartan tablet contains, depending on the dosage, 25, 50 or 100mg of the active ingredient losartan. Additional components include polyoxyethylene stearate, colloidal anhydrous silica, sodium stearyl fumarate, croscarmellose sodium, microcrystalline cellulose, hypromellose and titanium dioxide (E171). If you think you may be allergic to any of the ingredients mentioned above, please ask a doctor before taking the first tablet of your course.


Losartan tablets are available in 25, 50 and 100mg doses. Which dosage you require depends on your condition and which other medication you're currently taking. Your GP will set the exact dosage you need and adjust it if necessary. The most common dosage is 50mg per day. Elderly patients or those suffering from liver problems may require a lower dosage, as do children. Please ensure you follow your doctor’s instructions and do not exceed the recommended intake.
