What is in this leaflet
This leaflet answers some common questions about SEVIKAR HCT. It does not contain
all the available information. It does not take the place of talking to your doctor
All medicines have risks and benefits. Your doctor has weighed the risks of you taking
SEVIKAR HCT against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What SEVIKAR HCT is used for
SEVIKAR HCT 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 SEVIKAR HCT works
SEVIKAR HCT contains olmesartan medoxomil, which 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. SEVIKAR HCT blocks the action of angiotensin-II
and therefore relaxes your blood vessels. This helps lower your blood pressure.
SEVIKAR HCT also contains amlodipine besilate, a calcium channel blocker. This reduces
the movement of calcium into the cells of the heart and blood vessels. This also helps
to lower blood pressure as it relaxes the blood vessels and increases the supply of
blood and oxygen to the heart.
SEVIKAR HCT also contains hydrochlorothiazide, a diuretic which reduces the amount
of fluid in the body. This also helps to lower blood pressure.
Your doctor may have prescribed SEVIKAR HCT for another reason. Ask your doctor if
you have any questions about why SEVIKAR HCT has been prescribed for you.
This medicine is available only with a doctor's prescription.
The safety and effectiveness of SEVIKAR HCT in children and teenagers under the age
of 18 years have not been established.
SEVIKAR HCT is not addictive.

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.
