Patients with High Blood Pressure
The usual dose of Losartan Potassium Tablets for most patients is one 50 mg tablet once a day. The maximal reduction in blood pressure
should be reached 3-6 weeks after starting treatment. In some patients, the doctor may prescribe a higher dose (such as 100 mg). Follow your
doctor's instructions exactly. If you have the impression that the effect of Losartan Potassium Tablets is too strong or too weak, tell your doctor
or pharmacist.
Patients with High Blood Pressure and Type 2 diabetes
The usual starting dose of Losartan Potassium Tablets is 50 mg once daily. The dose may be increased to 100 mg once daily depending onyour
blood pressure response.
Losartan Potassium Tablets may be given with other medicines used to lower blood pressure, as well as insulin and other medicines which
decrease the level of glucose in the blood.
Patients with Heart Failure
Treatment usually starts with 12.5mg of losartan once a day. Generally, the dose is increased gradually (i.e. 12.5mg daily during the first week,
25mg daily during the second week and 50mg daily during the third week).
In the treatment of heart failure, losartan is usually given with a diuretic (medicine that increases the amount of water which you pass 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
In patients over 75 years of age, the doctor may prescribe a lower dose.
A lower dose may also be prescribed in patients given high doses of diuretics or in patients with liver disorders. The use of losartan should not
be given to patients with severe liver problems (see section 2, "Do not take Losartan Potassium Tablets if..").
Keep taking the medicine until your doctor tells you to stop. Do not stop taking the tablets just because you feel better. If you stop taking them
your condition may get worse.

1. What Losartan Potassium Tablets are and what they are used for

Losartan Potassium belongs to a group of medicines known as angiotensin-II antagonists.

Take this leaflet, and any tablets that you still have to show the doctor.
An overdose of this medicine may be dangerous; the symptoms of overdose are low blood pressure, increased heartbeat or possibly a
decreased heartbeat.

In patients with type 2 diabetes, where there has been damage to the kidneys (shown by the presence of protein in the urine), Losartan
Potassium (can provide kidney protection by blocking the harmful effects of angiotensin II (a chemical in the body which tightens blood
vessels causing blood pressure to increase) and slowing the worsening of kidney damage.
Losartan Potassium is also used to treat chronic heart failure if another medicine, called an ACE inhibitor, is not considered to be suitable by
your doctor. If your heart failure has been stabilised with an ACE inhibitor, you should not be switched to losartan potassium.

Try to take Losartan Potassium Tablets daily as prescribed. However, if you miss a dose, just carry on with the next dose as normal. Do not take
