Consumer Medicine Information


This leaflet answers some common questions about Telmisartan/HCT Sandoz.

It does not contain all available information. It does not take the place of talking to your doctor or pharmacist.

This medicine 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 Telmisartan/HCT Sandoz works

This medicine contains the active ingredients telmisartan and hydrochlorothiazide. 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 Telmisartan/HCT Sandoz for another reason.

Telmisartan/HCT Sandoz is not addictive.

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

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking 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, ask your doctor or pharmacist for help. 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.

How much to take

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow the instructions they give you.

The usual dose for adults is one Telmisartan/HCT Sandoz 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 Telmisartan/HCT Sandoz 80/12.5 mg tablet once a day.

If your blood pressure is still not satisfactorily controlled with Telmisartan/HCT Sandoz 80/12.5 mg, your doctor may increase your dose to one Telmisartan/HCT Sandoz 80/25 mg tablet once a day.

When to take it

Take your medicine 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 your medicine with or without food. It does not matter if you take your medicine before or after food.

How to take it

Swallow the tablet whole with a full glass of water.

How long to take it

Continue taking your medicine for as long as your doctor tells you.

This medicine helps control your condition, but does not cure it. It is important to keep taking your medicine 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

Take your dose as soon as you remember, and continue to take it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

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 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 or New Zealand 0800 POISON or 0800 764766)) for advice or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much Telmisartan/HCT Sandoz.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include feeling dizzy, light-headed or faint. Your heartbeat may be faster or lower than usual. You may experience dehydration, nausea, drowsiness and muscle spasm.


Things you must do

If you are about to be started on any new medicine, tell your doctor or pharmacist that you are taking Telmisartan/HCT Sandoz.

Tell any other doctors, dentists and pharmacists who are treating you that you are taking this medicine.

If you are going to have surgery, tell your surgeon and anaesthetist that you are taking this medicine. It may affect other medicines used during surgery.

Keep all of 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.

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 (non-melanoma skin cancer).

Protect your skin from sun exposure and UV rays while taking this medicine.

If you develop any severe shortness of breath or difficulty breathing after taking TELMISARTAN/HCT SANDOZ, seek medical attention immediately.

Tell your doctor if, for any reason, you have not used Telmisartan/HCT Sandoz exactly as prescribed. Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.

If you become pregnant while taking this medicine, tell your doctor immediately. You should not take this medicine while you are pregnant.

Things you must not do

Do not take Telmisartan/HCT Sandoz to treat 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 Telmisartan/HCT Sandoz 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 Telmisartan/HCT Sandoz affects you.

Like other medicines used to treat high blood pressure. This medicine 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/HCT Sandoz, especially if you are also taking a diuretic (or fluid tablet) or if you are dehydrated.

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.

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 Telmisartan/HCT Sandoz.

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:

  • decrease in vision or pain in your eyes due to high pressure (possible signs of fluid accumulation in the vascular layer of the eye or acute angle-closure glaucoma).

Tell your doctor as soon as possible if you notice any of the following:

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 and a very fast heart rate, may mean that the hydrochlorothiazide part of Telmisartan/HCT Sandoz is having an excessive effect.

You should tell your doctor if you experience any of these symptoms.

Tell your doctor as soon as possible if you notice any unexpected changes to your skin, including your lips. This could be a type of skin or lip cancer (non-melanoma skin cancer).

If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:

  • 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
  • acute respiratory distress which is a very rare but possible side effect (signs include severe shortness of breath, fever, weakness and confusion)
  • increased sensitivity of the skin to the sun with symptoms of sunburn (such as redness, itching, swelling, blistering) which may occur more quickly than normal.

The above list includes 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 unwell. Other side effects not listed above may also occur in some people.
