What OLMESARTAN HCT – MYL is used for
OLMESARTAN HCT – 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 HCT – MYL works
OLMESARTAN HCT – 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 HCT – MYL blocks the action of angiotensin-II and therefore relaxes your blood vessels. This helps lower your blood pressure.
OLMESARTAN HCT – MYL also contains a diuretic which reduces the amount of fluid in the body. This also helps to lower blood pressure.
Your doctor may have prescribed OLMESARTAN HCT – MYL for another reason. Ask your doctor if you have any questions about why OLMESARTAN HCT – MYL has been prescribed for you.
OLMESARTAN HCT – MYL is not addictive.
This medicine is available only with a doctor's prescription.

If this occurs do not drive. If you drink alcohol, dizziness or light-headedness may be worse.
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 (preferably wholegrain), cereals and fish. Also eat less sugar and fat (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, organisations and strategies to help you quit. Ask your doctor or pharmacist for further information and advice.
