What this medicine is used for
Telmisartan is used to:
- treat high blood pressure (also called hypertension)
- prevent cardiovascular complications, including death due to cardiovascular causes, in patients aged 55 years of age or older with coronary artery disease, peripheral vascular disease, previous stroke, previous transient ischaemic attack (TIA) or high-risk diabetes with evidence of end organ damage
High blood pressure (hypertension)
Everyone has blood pressure. This pressure helps your blood move 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 normal, even when you are calm or relaxed.
There are usually no signs 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.
Prevention of cardiovascular complications, including death due to cardiovascular causes
Patients who may be considered at a high risk of developing cardiovascular complications, or at a high risk of death due to cardiovascular causes, are those aged 55 or more who have problems such as coronary artery disease (a heart disease caused by poor blood flow in the blood vessels of the heart), peripheral vascular disease (poor circulation in the hands or feet), previous stroke, previous transient ischaemic attack (TIA) or diabetes with additional high risk factors and evidence of end organ damage (e.g. damage occurring in the kidneys, heart, brain or eyes).
Your doctor can tell you if you are at a high risk of developing cardiovascular complications or if you are at a high risk of death due to cardiovascular causes.
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, the blood vessels relax and your blood pressure goes down.
Telmisartan may be used either alone or in combination with other medicines used to treat high blood pressure.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.
There is not enough information to recommend the use of this medicine for children under the age of 18 years.

How to take this medicine
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the directions, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
For the treatment of high blood pressure (hypertension):
The usual dose for adults is one 40 mg tablet, once a day.
If your blood pressure is still to
o high after 4-8 weeks of starting treatment, your doctor may increase your dose to 80 mg.
For the prevention of cardiovascular complications, including death due to cardiovascular causes:
The usual dose is one 80 mg tablet, once a day.
Depending on how you respond to the treatment, your doctor may suggest a higher or lower dose.
How to take it
Swallow the tablet whole with a full glass of water.
When to take it
Take your medicine 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 it before, with or after food.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
Telmisartan helps to control your high blood pressure, and/or prevents you from developing cardiovascular complications, but does not cure it. It is important to keep taking telmisartan every day, even if you feel well.
People who have high blood pressure often feel well and do not notice any symptoms.
If you forget to take it
If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much telmisartan you may feel dizzy, light-headed or faint. Your heartbeat may be faster or lower than usual and you may experience rapid, shallow breathing or cold, clammy skin. This is because your blood pressure is too low.
While you are taking this medicine
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.
If you become pregnant or start to breastfeed while taking this medicine, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.
Keep all your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Things you must not do
Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.
Things to be careful of
Be careful when driving or operating machinery until you know how this medicine affects you. Like other medicines used to treat high blood pressure, telmisartan may cause sleepiness, dizziness or light headedness in some people.
If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
You may feel dizzy or light-headed when you begin to take telmisartan, especially if you are also taking a diuretic (or fluid tablet) or if you are dehydrated.
If this medicine makes you feel dizzy or light-headed, be careful when getting up from a sitting or lying position. 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.
If you exercise, sweat or if the weather is hot, you should drink plenty of water.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking this medicine.
