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 in cooking or at the table and avoid cooked or processed foods containing high sodium (salt) levels.

Regular exercise also improves your blood cholesterol levels, helps reduce your weight and stress levels, and improves your

find a route that is reasonably flat. Before starting any exercise, ask your doctor about the best kind of programme for
