6. Further information
The name of your medicine is Losartan potassium 25 mg, 50 mg or 100 mg film-coated tablets.
(referred to as Losartan in this leaflet)
Losartan belongs 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 treat patients with chronic heart failure when therapy with specific medicines called ACE
inhibitors is not considered suitable by your doctor.
You should not be switched to losartan if your heart failure has been stabilised with an ACE
• to lower blood pressure in people who have high blood pressure
If you have high blood pressure AND you have diabetes (treated by tablets or diet) and kidney
problems THEN losartan will help protect your kidneys.
If you have high blood pressure AND you have been shown to have thickened heart muscle
THEN losartan has been shown to reduce your risk of stroke.

Do not take Losartan:
• if you are allergic (hypersensitive) to losartan or to any of its other ingredients
• if you have severe liver problems
• if you are more than 3 months pregnant. (It is also better to avoid Losartan in early
pregnancy-see pregnancy section.)
Take special care with Losartan
You must tell your doctor if you think you are (or might become) pregnant. Losartan is not
recommended in early pregnancy, and must not be taken if you are more than 3 months pregnant,
as it may cause serious harm to your baby if used at that stage (see pregnancy section).
It is important to tell your doctor before taking Losartan:
• if you have ever had swelling of the face, lips, throat, and/or tongue (also known as
• if you lose fluid through vomiting or diarrhoea
• if you are prescribed diuretics (medicines that increase the amount of water that you pass out
through your kidneys) or are under dietary salt restriction
• if you are known to have narrowing or blockage of the blood vessels leading to your kidneys
or if you have received a kidney transplant
• if you have liver problems
• if you have heart problems - caution is needed if you are treated with medicines known as ßblockers
• if you have ever had a stroke
• if you suffer from “primary hyperaldosteronism” (a hormone imbalance)

• 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, spironolactone or medicines containing potassium
such as heparin
• Pain-relieving medicines such as indometacin and medicines known as “cox-2-inhibitors”
because they may reduce the blood lowering effect of losartan. If you already have kidney
