What Twynsta is used for
Twynsta is used to lower high blood pressure (hypertension).
Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different
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 or 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 Twynsta works
Twynsta contains telmisartan and amlodipine (as the besylate salt) in one single tablet. These two active ingredients help
to reduce blood pressure in different ways:
Telmisartan belongs to a group of medicines called angiotensin II receptor antagonists. Angiotensin II is a substance in
the body which causes blood vessels to narrow, thus increasing blood pressure. Telmisartan works by blocking the effect of
angiotensin II. When the effect of angiotensin II is blocked, your blood vessels relax and your blood pressure goes down.
Amlodipine belongs to a group of medicines called calcium channel blockers. Amlodipine blocks calcium from moving into the
cells of the heart and blood vessels. As a result, they relax the blood vessels and increase the supply of blood and oxygen
to the heart while reducing its workload.
This means that both of these active ingredients work together to help stop your blood vessels tightening. As a result, the
blood vessels relax and blood pressure is lowered.
Your doctor may have prescribed Twynsta for another reason.
Ask your doctor if you have any questions about why Twynsta has been prescribed for you.
Twynsta is not addictive.
This medicine is available only with a doctor's prescription.

These medicines may be affected by Twynsta or may affect how well it works. You may need different amounts of your medicine,
or you may need to take different medicines.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Twynsta.
How to take Twynsta
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
Your doctor or pharmacist will tell you how many tablets you will need to take each day. This depends on your condition and
whether or not you are taking any other medicines.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
The usual dose is one tablet a day.
Depending on how you respond to the treatment, your doctor may suggest a higher or lower dose.
It is important to take Twynsta exactly as your doctor or pharmacist has told you.
How to take it
Swallow the tablet whole with a full glass of water.
When to take it
Take Twynsta at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take Twynsta before or after food.
How long to take it
Continue taking Twynsta for as long as your doctor tells you.
Twynsta helps to control your high blood pressure, but does not cure it. It is important to keep taking Twynsta every day
even if you feel well.
People who have high blood pressure often feel well and do not notice any signs of this problem.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take the dose as soon as you remember, and then go back to taking it as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Emergency at your
nearest hospital if you think that you or anyone else may have taken too much Twynsta. Do this even if there are no signs
of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Twynsta, you may feel dizzy, light-headed or you may faint. Your heartbeat may be faster or slower than
usual. You may experience rapid, shallow breathing or cold, clammy skin. This is because your blood pressure is too low.
While you are taking Twynsta
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Twynsta.
Tell any other doctors, dentists and pharmacists who treat you that you are taking Twynsta.
Make sure you drink enough water during exercise and hot weather when you are taking Twynsta, especially if you sweat a lot.
If you do not drink enough water while taking Twynsta, you may feel faint, light-headed or sick. This is because your blood
pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
If you have excess vomiting or diarrhoea while taking Twynsta, tell your doctor.
You may lose too much water and salt and your blood pressure may drop too much.
If you feel light-headed or dizzy after taking your first dose of Twynsta, or when your dose is increased, tell your doctor
This is especially important if you are taking Twynsta for heart failure.
Your blood pressure may drop suddenly.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking Twynsta.
It may affect other medicines used during surgery.
If you become pregnant while taking Twynsta, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are taking Twynsta.
It may interfere with the results of some tests.
Keep all of your doctor's appointments so that your progress can be checked.
Your doctor may check your blood pressure from time to time to make sure Twynsta is working and to prevent unwanted side effects.
Your doctor may occasionally do a blood test to check your potassium levels and see how your kidneys are working.
Things you must not do
Do not take Twynsta to treat any other complaints unless your doctor tells you to.
Do not give Twynsta to anyone else, even if they have the same condition as you.
Do not stop taking Twynsta, or lower the dosage, without checking with your doctor.
Things to be careful of
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
Standing up slowly, especially when you get up from a bed or chair, will help your body get used to the change in position
and blood pressure. If this problem continues or gets worse, talk to your doctor.
Be careful driving or operating machinery until you know how Twynsta affects you.
As with other medicines in this class, Twynsta may cause dizziness, light-headedness or tiredness in some people. Make sure
you know how you react to Twynsta before you drive a car, operate machinery, or do anything else that could be dangerous if
you are dizzy or light-headed. 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 low-fat diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less
fat and sugar.
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.
Exercise - regular exercise helps to reduce blood pressure and helps get the heart fitter, but it is important not to overdo
it. Walking is good exercise, but 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.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Twynsta.
Twynsta helps most people with high blood pressure, but it may have unwanted side effects in a few people. All medicines
can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you
get some of the side effects.
Do not be alarmed by the following list of possible side effects.
