What Micardis Plus is used for
Micardis Plus is used to lower 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 is needed, 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.
How Micardis Plus works
Micardis Plus contains telmisartan and hydrochlorothiazide 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.
Hydrochlorothiazide belongs to the group of medicines called diuretics. Diuretics help to reduce the amount of excess fluid in the body by increasing the amount of urine produced. They help with lowering blood pressure particularly when used with other blood pressure lowering medicines.
Your doctor may have prescribed Micardis Plus for another reason.
Ask your doctor if you have any questions about why Micardis Plus has been prescribed for you.
Micardis Plus is not addictive.
This medicine is available only with a doctor's prescription.

How to take Micardis Plus
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 for adults is one Micardis Plus 40/12.5 mg tablet once a day.
If your blood pressure is still too high after 4-8 weeks of starting treatment, your doctor may increase your dose to one Micardis Plus 80/12.5 mg tablet once a day.
If your blood pressure is still not satisfactorily controlled with Micardis Plus 80/12.5 mg, your doctor may increase your dose to one Micardis Plus 80/25 mg tablet once a day.
It is important to take Micardis Plus 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 Micardis Plus at about the same time each day, either morning or evening.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
You can take Micardis Plus with or without food.
How long to take it
Continue taking Micardis Plus for as long as your doctor tells you.
Micardis Plus helps control your high blood pressure but does not cure it. It is important to keep taking Micardis Plus 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 unwanted side effects.
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 Micardis Plus.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Micardis Plus you may feel dizzy, light-headed or faint. Your heartbeat may be faster or slower than usual. You may experience dehydration, nausea, drowsiness and muscle spasm.
While you are taking Micardis Plus
Things you must do
Tell any other doctors, dentists and pharmacists who are treating you that you are taking Micardis Plus.
If you are about to be started on any new medicine, tell your doctor or pharmacist that you are taking Micardis Plus.
If you feel that Micardis Plus is not helping your condition, tell your doctor or pharmacist.
Tell your doctor if, for any reason, you have not used Micardis Plus exactly as prescribed.
Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.
Tell your doctor immediately if you become pregnant while taking Micardis Plus.
If you are going to have surgery, tell your doctor, surgeon and anaesthetist that you are taking Micardis Plus.
Micardis Plus may affect some medicines you receive during surgery.
Things you must not do
Do not take Micardis Plus to treat any other complaints unless your doctor tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not stop taking Micardis Plus 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 Micardis Plus affects you.
Like other medicines used to treat high blood pressure, Micardis Plus 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 Micardis Plus, especially if you are also taking a diuretic (or fluid tablet) or if you are dehydrated.
If you feel dizzy or light-headed, and you wish to stand up, you should do so 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.
If you exercise, or if you 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 Micardis Plus.
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 this 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 if you notice any of the following and they worry you:
fainting, dizziness or spinning sensation
a feeling of tension or fullness in the nose, cheeks and behind the eyes, sometimes with a throbbing ache (sinusitis)
infections of the air passages
shortness of breath or difficulty breathing
abnormal or blurred vision
changes in heart rhythm or increased heart rate
rash or redness or itchiness of skin
dizziness or light-headedness when you stand up (postural hypotension)
stomach pain or discomfort (abdominal pain, dyspepsia, gastritis)
wind or excessive gas in the stomach or bowel
diarrhoea or constipation
pins and needles
sleep disturbances or trouble sleeping
leg pain or cramps in legs
aching muscles or aching joints not caused by exercise or muscle spasms
changes in the levels of potassium or sodium or uric acid in your blood (such changes are usually detected by a blood test).
Tell your doctor as soon as possible if you experience any side effects during or after taking Micardis Plus, so that these may be properly treated.
Symptoms such as feeling very thirsty, sleepy, sick or vomiting, a dry mouth, general weakness, muscle pain or cramps, a very fast heart rate, may mean that the hydrochlorothiazide part of Micardis Plus is having an excessive effect.
You should tell your doctor if you experience any of these symptoms.
Tell your doctor immediately or go to Emergency at your nearest hospital if you notice any of the following:
swelling of the face, lips, mouth, tongue or throat which may cause difficulty in swallowing or breathing
severe and sudden onset of pinkish, itchy swellings on the skin, also called hives or nettle rash
developing or worsening of a disease called systemic lupus erythematosus which affects the skin, joints and kidney.
These are serious side effects. You may need urgent medical attention or hospitalisation. These side effects are rare.
Tell your doctor or pharmacist if you notice anything else that is making you feel unwell.
Other side effects not listed above may also occur in some people.
After taking Micardis Plus
Keep the tablets in the blister strip until it is time to take a dose.
The blister pack protects the tablets from light and moisture.

Do not store Micardis Plus or any other medicine in the bathroom or near a sink. Do not leave it in the car or on a window sill.
