1. WHAT YOUR MEDICINE IS AND WHAT IT IS USED FOR


The name of your medicine is Losartan potassium/Hydrochlorothiazide 50mg/12.5mg or 100mg/25mg Film-coated Tablets. Your medicine is referred to as Losartan potassium/Hydrochlorothiazide Tablets or “your medicine” throughout this leaflet.

Losartan potassium/Hydrochlorothiazide Tablets contain medicines called losartan potassium and hydrochlorothiazide. Both of these medicines reduce blood pressure.

•    Losartan potassium belongs to a class of medicines known as angiotensin II receptor antagonists. Losartan potassium helps blood vessels relax and so lowers blood pressure.

•    Hydrochlorothiazide belongs to a group of medicines called thiazide diuretics (also known as “water tablets”). Hydrochlorothiazide works by making the kidneys pass more water and salt and this leads to a reduction in blood pressure.

Losartan potassium/Hydrochlorothiazide Tablets are used to treat high blood pressure not adequately controlled by either losartan potassium or hydrochlorothiazide when taken on their

own.

People with high blood pressure often do not notice any signs of this problem. Many may feel quite normal. High blood pressure increases the workload of the heart and may damage arteries. High blood pressure increases the risk of heart attacks, stroke and kidney failure. Lowering your blood pressure reduces the risk of developing these disorders.
