What OLMESARTAN - MYL is used for
OLMESARTAN - MYL is used to treat high blood pressure which is sometimes called hypertension.
Everyone has blood pressure. This pressure helps push blood all around your body.
Your blood pressure changes at different times of the day, depending on how busy or
worried you are. You have hypertension (high blood pressure) when your blood pressure
stays higher than is needed, even when you are calm and relaxed.
There are usually no symptoms of hypertension. The only way of knowing that you have
hypertension is to have your blood pressure checked on a regular basis. If high blood
pressure is not treated it can lead to serious health problems, including stroke,
heart disease and kidney failure.
How OLMESARTAN - MYL works
OLMESARTAN - MYL belongs to a group of medicines known as angiotensin-II receptor
antagonists. Angiotensin-II is a substance produced in the body which causes blood
vessels to tighten. OLMESARTAN - MYL blocks the action of angiotensin-II and therefore
relaxes your blood vessels. This helps lower your blood pressure.
Your doctor may have prescribed OLMESARTAN - MYL for another reason. Ask your doctor
if you have any questions about why OLMESARTAN - MYL has been prescribed for you.
OLMESARTAN - MYL is not addictive.
This medicine is available only with a doctor's prescription.

Things that would be helpful for your blood pressure
Some self help measures suggested below may help your condition. Talk to your doctor
or pharmacist about these measures and for more information.
Alcohol - your doctor may advise you to limit your alcohol intake.
Weight - your doctor may suggest losing some weight to help lower your blood pressure
and help lessen the amount of work your heart has to do. Some people may need a dietician's
help to lose weight.
Diet - eat a healthy diet which includes plenty of fresh vegetables, fruit, bread,
cereals and fish.
Also eat less fat and sugar (especially saturated fat) which includes sausages, fatty
meats, full cream dairy products, biscuits, cakes, pastries, chocolates, chips and
coconut. Monounsaturated and polyunsaturated fats from olive oil, canola oil, avocado
and nuts are beneficial in small quantities.
Salt - your doctor may advise you to watch the amount of salt in your diet. To reduce
your salt intake you should avoid using salt in cooking or at the table and avoid
cooked or processed foods containing high sodium (salt) levels.
Exercise - regular exercise, maintained over the long term, helps to reduce blood
pressure and helps get the heart fitter. Regular exercise also improves your blood
cholesterol levels, helps reduce your weight and stress levels, and improves your
sleep, mood and ability to concentrate. However, it is important not to overdo it.
Walking is good exercise, but try to find a route that is reasonably flat. Before
starting any exercise, ask your doctor about the best kind of programme for you.
Smoking - your doctor may advise you to stop smoking or at least cut down. There
are enormous benefits to be gained from giving up smoking. There are many professionals,

further information and advice.
