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 besilate 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.

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.
Talk to your doctor if you are elderly and your dose needs to be increased.
Your doctor may monitor your condition more closely.
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 immediately.
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.
You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
feeling light-headed, dizzy or faint
swelling of hands, ankles or feet
sleepiness or tiredness, weakness or difficulty sleeping
tingling, numbness or pain in the hands or feet, pins and needles
taste disturbances or loss of taste

flushed or pale skin
feeling sick (nausea) or vomiting
tender or enlarged gums
an uncomfortable feeling in the stomach or belching after eating (indigestion)
itching, rash, redness of skin
pain in joints
aching, tender or weak muscles not caused by exercise

severe and sudden onset of itchy or raised skin rash, hives or nettle rash.
These are very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are rare.
Other side effects not listed above may also occur in some people.
Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
After taking Twynsta
Keep your tablets in the original blister strip until it is time to take them.
The blister pack protects the tablets from light and moisture.
Keep your tablets in a cool dry place where the temperature stays below 30°C.
Do not store Twynsta or any other medicine in the bathroom or near a sink.
Do not leave it on a window sill or in the car.
Heat and dampness can destroy some medicines.
Keep it where children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor tells you to stop taking Twynsta or the expiry date has passed, ask your pharmacist what to do with any tablets that are left over.
