What this medicine is used for

APO-Telmisartan HCTZ 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 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.

Untreated hypertension can lead to serious health problems, including stroke, heart disease and kidney failure.

APO-Telmisartan HCTZ contains both telmisartan and hydrochlorothiazide (HCTZ) 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

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

This medicine is not addictive.

This medicine is available only with a doctor’s prescription.

The safety and effectiveness of this medicine in children and teenagers up to 18 years of age have not been established.

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 instructions on the label, ask your doctor or pharmacist for help.

How much to take

Your doctor or pharmacist will tell you how many tablets you will need to take each day. This depends on your condition and whether you are taking any other medicines.

The usual dose for this medicine is one tablet taken once a day.

If your blood pressure is still too high after 4-8 weeks of starting treatment, your doctor may increase your dose.

If your blood pressure is still not satisfactorily controlled, your doctor may increase your dose.

When to take it

Take this 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.

How to take it

Swallow the tablet whole with a full glass of water.

You can take it with or without food.

How long to take it for

Take this medicine every day until your doctor tells you to stop.

This medicine helps control your high blood pressure but does not cure it. It is important to keep taking it 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 the Emergency department at your nearest hospital, if you think that you or anyone else may have taken too much medicine. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. If you take too much, you may feel dizzy, light-headed or faint. Your heartbeat may be faster or lower than usual. You may experience dehydration, nausea, drowsiness and muscle spasm.

While you are taking this medicine

Things you must do

Tell your doctor if you develop an unexpected abnormal lump, bump, ulcer, sore or coloured area on the skin (skin lesion) during the treatment. Treatment with hydrochlorothiazide, particularly long-term use with high doses, may increase the risk of some types of skin and lip cancer (nonmelanoma skin cancer).

Things to be careful of

You may feel dizzy or light-headed when you begin to take this medicine, especially if you are also taking a diuretic 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 or sweat, or if the weather is hot, you should drink plenty of water.

Symptoms such as feeling very thirsty, sleepy, sick or vomiting, a dry mouth, general weakness, restlessness, seizures (fits), confusion, muscle pain or cramps, passing less urine than normal, a very fast heart rate, may mean that the HCTZ part of telmisartan/HCTZ is having an excessive effect.

  • acute respiratory distress which is very rare but possible side effect (signs include severe shortness of breath, fever, weakness and confusion).
