Chemmart Gliclazide MR

What this medicine is used for

The name of your medicine is Chemmart Gliclazide MR. It contains the active ingredient gliclazide.

The tablets release the gliclazide gradually over 24 hours.

The medicine is used to control, blood glucose in patients with Type II diabetes mellitus.

This type of diabetes is also known as non-insulin-dependent diabetes mellitus (NIDDM) or maturity onset diabetes.

Gliclazide is used when diet and exercise are not enough to control your blood glucose.

Gliclazide can be used alone, or together with other medicines for treating diabetes

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 available only with a doctor's prescription.

How it works

Gliclazide belongs to a group of medicines called the sulfonylureas.

Gliclazide lowers high blood glucose by increasing the amount of insulin produced by your pancreas.

Glucose is used by the body as fuel, and all people have glucose circulating in their blood.

In diabetes, levels of blood glucose are higher than is needed. This is called hyperglycaemia.

A section at the end of this leaflet contains advice about recognising and treating hyperglycaemia.

It is very important to control high blood glucose whether or not you feel unwell. This really helps to avoid serious long-term health problems, which can involve the heart, eyes, circulation, and/or kidneys.

As with many medicines used for the treatment of diabetes, there is a possibility that blood glucose levels may become very low during treatment with gliclazide.

This is known as hypoglycaemia.

A section at the end of this leaflet contains advice about recognising and treating hypoglycaemia.

There is no evidence that this medicine is addictive.

Be careful driving or operating machinery until you know how gliclazide affects you.

Gliclazide may cause dizziness and drowsiness in some people.

Use in children

This medicine should not be used in children.

Before you take this medicine

When you must not take it

Do not take this medicine if:

1. You have or have had any of the following:

  • Type I diabetes mellitus (insulin dependent diabetes mellitus, also known as IDDM, or juvenile or growth onset diabetes)
  • unstable or brittle diabetes
  • diabetic acidosis
  • diabetic coma or pre-coma
  • a history of repeated ketoacidosis or coma
  • severe kidney disease
  • severe liver disease

2. You are pregnant or planning to become pregnant.

Gliclazide may affect your developing baby if you take it during pregnancy. Your doctor will usually replace gliclazide with insulin while you are pregnant.

3. You are breast-feeding or plan to breast-feed.

It is not known whether gliclazide passes into human breast milk.

4. You are using miconazole to treat fungal infections.

5. You are taking medicines called phenylbutazone or danazol. You should not take these while taking gliclazide.

6. The expiry date (EXP) printed on the pack has passed.

7. The packaging is torn, shows signs of tampering or it does not look quite right.

8. You have had an allergic reaction to:

  • gliclazide or other sulfonylureas
  • antibiotics called sulfonamides
  • thiazide diuretics (a type of "fluid" or "water" tablet)
  • any of the ingredients listed at the end of this leaflet.
Symptoms of an allergic reaction may include cough, shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue, throat or other parts of the body, rash, itching or hives on the skin; fainting or hayfever-like symptoms.
If you think you are having an allergic reaction, do not take any more of the medicine and contact your doctor immediately or go to the Accident and Emergency department at the nearest hospital.

  • some medicines used to treat high blood pressure and other heart conditions, such as beta-blockers, ACE inhibitors
  • some hormones used in hormone replacement therapy and oral contraceptives (oestrogens and progestogens)
  • monoamine oxidase inhibitors (MAOIs), used for treating depression, Parkinsons Disease or infections
  • some medicines used for mental illness (e.g. chlorpromazine)
  • some medicines for epilepsy such as phenobarbitone
  • clofibrate, a medicine for lowering cholesterol
  • medicines used to treat arthritis, pain and inflammation (e.g. oxyphenbutazone, phenylbutazone, high dose salicylates)
  • antibiotics called sulfonamides, or chloramphenicol
  • miconazole, or fluconazole, used to treat fungal infections

  • salbutamol and terbutaline, medicines for asthma
  • diuretics, also known as fluid tablets (e.g. chlorothiazide)

If you are taking any of these you may need a different dose or you may need to take different medicines.

Remember to keep checking your blood glucose levels.

Drinking alcohol can also affect your blood sugar levels and how well gliclazide works. If taken with gliclazide, it can also cause flushing of the face, throbbing headache, giddiness, fast breathing, fast heart rate, angina, stomach pains or feeling sick or vomiting.

Other medicines not listed above may also interact with gliclazide.

How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist or diabetes educator.

Their instructions may be different to the information in this leaflet.

How much to take

Your doctor or pharmacist 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.

The starting dose is usually 30 mg per day. This will be adjusted slowly over several weeks, depending on how well your body responds to the dose.

The usual dose of this medicine may vary from one to four tablets each day.

Your doctor may increase or decrease the dose, depending on your blood glucose levels.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the tablets whole with a glass of water.

Do not crush the tablets or break them.

When to take it

Take it at about the same time each day, usually with breakfast.

Taking these tablets with food can help to minimise the risk of hypoglycaemia.

It will also help you remember when to take them.

Do not skip meals while taking these tablets.

How long to take it for

Gliclazide can help to control your blood glucose level, but it cannot cure your Type 2 diabetes.

Gliclazide treatment is usually for a long period of time - so you should keep taking the tablets regularly unless advised otherwise by your doctor.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

Take your next planned dose at the usual time and continue as normal.

Do not take a double dose to make up for the dose that you missed.

If you double a dose, this may cause hypoglycaemia (low blood glucose).

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 to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.

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

If you take too much gliclazide you may experience symptoms of hypoglycaemia (low blood glucose).

If not treated quickly, these symptoms may progress to loss of co-ordination, slurred speech, confusion, loss of consciousness and fitting.

At the first signs of hypoglycaemia (low blood glucose), raise your blood glucose quickly by taking jelly beans, sugar or honey, (non-diet) soft drink or glucose tablets.

Note that artificial sweeteners will not help to raise your blood sugar levels.

While you are taking this medicine

Things you must do

Take your tablets exactly as your doctor has prescribed.

Otherwise you may not get the full benefits from treatment.

Make sure you check your blood glucose levels regularly. This is the best way to tell if your diabetes is being controlled properly.

Your doctor or diabetes educator will show you how and when to do this.

Make sure that you, your friends, family and work colleagues can recognise the symptoms of hypoglycaemia (low blood glucose) and hyperglycaemia (high blood glucose) and know what to do.

Instructions at the end of this leaflet can help you with this.

Visit your doctor for regular blood tests and checks of your eyes, feet, kidneys, heart, circulation, blood, and blood pressure.

Carefully follow your doctor's and dietician's advice on diet, drinking alcohol and exercise.

Tell your doctor immediately if you notice the return of any symptoms of hyperglycaemia that you had before starting gliclazide, or if your blood sugar levels are high.

These may be signs that gliclazide is no longer working, even though you may have been taking it successfully for some time.

If you are elderly or are taking other medicines for diabetes such as insulin or metformin, the risk of hypoglycaemia (low blood glucose) is increased.

The risk of hypoglycaemia (low blood glucose) is also increased in the following situations:

  • too much gliclazide
  • too much or unexpected exercise
  • delayed meal or snack
  • too little food.

If you experience any of the signs of high blood glucose (hyperglycaemia), contact your doctor immediately.

The risk of hyperglycaemia (high blood glucose) is increased in the following situations:

  • undiagnosed or uncontrolled diabetes
  • illness, infection or stress
  • too little gliclazide
  • certain other medicines
  • too little exercise
  • eating more carbohydrate than normal.

If you become ill or experience extra stress, injury, fever, infection or need surgery, tell your doctor.

Your blood glucose may become difficult to control at these times. Your doctor may decide to change your treatment and use insulin instead of gliclazide.

Tell your doctor that you are taking this medicine if:

  • you are about to be started on any new medicine
  • you are pregnant or are planning to become pregnant (tell your doctor immediately)
  • you are breast-feeding or are planning to breast-feed
  • you are about to have any blood tests
  • you are going to have surgery or an anaesthetic or are going into hospital.

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

Things you must not do

Do not:

  • Give this medicine to anyone else, even if their symptoms seem similar to yours
  • Take your medicine to treat any other condition unless your doctor or pharmacist tells you to
  • Stop taking your medicine, or change the dosage, without first checking with your doctor
  • Skip meals while taking gliclazide.

Things to be careful of

Be careful when driving or operating machinery until you know how this medicine affects you.

Gliclazide may cause dizziness and drowsiness in some people.

Drinking alcohol can make this worse. If you do feel dizzy or drowsy, do not drive, operate machinery or do anything else that could be dangerous.

Be careful not to let your blood glucose levels fall too low.

Low blood glucose levels may slow your reaction time and affect your ability to drive or operate machinery.

A section at the end of this leaflet contains advice about recognising and treating hypoglycaemia.

If you are travelling, it is a good idea to:

  • wear some form of identification showing you have diabetes
  • carry some form of sugar to treat hypoglycaemia (low blood glucose) if it occurs, for example, sugar sachets or jelly beans
  • carry emergency food rations in case of a delay, for example, dried fruit, biscuits or muesli bars
  • keep gliclazide tablets readily available.

If you become sick with a cold, fever or flu, it is very important to continue taking gliclazide, even if you feel unable to eat your normal meal.

If you have trouble eating solid food, use sugar-sweetened drinks as a carbohydrate substitute or eat small amounts of bland food.

Your diabetes educator or dietician can give you a list of foods to use for sick days.

Possible side effects

Tell your doctor, pharmacist, or diabetes educator as soon as possible if you do not feel well while you are taking gliclazide or if you have any questions or concerns.

Do not be alarmed by the following lists of side effects. You may not experience any of them. All medicines can have side effects. Sometimes they are serious but most of the time they are not.

Tell your doctor or pharmacist if you notice any of the following and they worry you.

This list includes the more common side effects. Mostly, these are mild:

  • Stomach upset including nausea and vomiting (feeling or being sick), heartburn, diarrhoea, constipation or a feeling of fullness in the stomach
  • sight problems (this may happen when you first start taking this medicine and your blood sugar levels change)
  • weariness
  • dizziness or giddiness
  • headache
  • mild rash or redness of the skin.

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

These may be serious side effects. You may need medical attention. Most of these side effects are rare.
