Losartan Tablets belong to a group of medicines known as angiotensin-II receptor blockers

(ARBs). Losartan can reduce blood

pressure and improve the ability of the heart to pump blood.

Losartan is used

•    to lower blood pressure in people with high blood pressure (hypertension)

•    to protect the kidney in 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 angiotension-converting-enzyme

inhibitors (ACE inhibitors) is not considered suitable by your doctor. If your heart failure has

been stabilized with an ACE

inhibitor you should not be switched to losartan.

•    in patients with high blood pressure and thickened heart muscle, losartan has been shown to decrease the risk of stroke.

Other medicines and Losartan Tablets

Talk to your doctor or pharmacist or nurse before taking 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 Tablets:

•    other blood pressure lowering medicines as they may additionally reduce your blood pressure. This list of medicines includes

baclofen, amifostine and medicines used for mental health such as amitriptyline and chlorpromazine,

•    medicines that affect potassium e.g. potassium supplements or certain diuretics ("water pills”) such as amiloride, triamterene,

spirinolactone or medicines containing potassium such as heparin,

•    pain relieving medicines such as indomethacin and medicines known as "Cox-2-inhibitors” because they may reduce the blood

pressure lowering effect of losartan,

If you already have kidney problems then using these medicines together with losartan may worsen your 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:

Pregnancy, breast-feeding and fertility

You should not take losartan in the first 12 weeks of pregnancy and you must not take them at all after the 13th week as their use during pregnancy may possibly be harmful to the baby.
