What VEXAZONE is used for

VEXAZONE is a tablet that is used to improve the action of the body's naturally produced insulin. VEXAZONE is used to treat type 2 diabetes mellitus not adequately controlled by diet and exercise.

Type 2 diabetes is also known as non-insulin dependent diabetes mellitus or adult-onset diabetes, and is controlled by diet, exercise, certain oral medications and occasionally insulin.

This medicine is also called pioglitazone and is a member of a class of drugs called glitazones. They are insulin-sensitising agents, which decrease insulin resistance. These medicines help control the level of sugar in your blood when you have type 2 diabetes by helping your body make better use of the insulin it produces.

VEXAZONE may be used on its own (when diet and exercise is not enough to treat your diabetes) or in combination with metformin and/or a sulphonylurea which are also oral anti-diabetic medicines.

It may also be used in combination with insulin.

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.

The use of VEXAZONE has not been studies in children.

Before you take VEXAZONE

When you must not take it

Do not take VEXAZONE if:

you have heart failure requiring treatment. Talk to your doctor if you have heart failure

type 1 diabetes or diabetic ketoacidosis (often caused by very high blood glucose levels)

you have an allergy to any medicine containing pioglitazone hydrochloride or any of the ingredients listed at the end of this leaflet (see 'Product Description')

Some of the symptoms of an allergic reaction may include shortness of breath; wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

Do not take VEXAZONE if you have heart failure requiring treatment.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.

If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

heart disease with shortness of breath after minimal physical activity

heart disease with severe symptoms at rest

swelling of hands, ankles or feet

bladder cancer or symptoms associated with bladder cancer such as blood in the urine (hematuria) often accompanied by pain and burning

liver problems

kidney problems that require dialysis. VEXAZONE is not recommended for use if you are on dialysis

Talk to your doctor about the risk of fracture and for advice on how to keep your bones healthy.

Bone fractures, usually in the hand, upper arm or foot, have been seen in some women when taking VEXAZONE.

Tell your doctor if you are pregnant or plan to become pregnant.

Like most medicines, VEXAZONE is not recommended for use during pregnancy. If there is a need to consider VEXAZONE during your pregnancy, your doctor will discuss with you the benefits and risks of taking VEXAZONE.

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known whether VEXAZONE passes into breast milk. Therefore, it is recommended to not breast-feed while taking this medicine.

Talk to your doctor if you are a woman who has not reached menopause, but have no menstrual periods.

Some women who do not have monthly periods and have not been through menopause may restart their periods when taking VEXAZONE. These women may be at increased risk of pregnancy.

Tell your doctor if you are using another medicine for diabetes.

VEXAZONE can enhance the action of other medicines. You may be at risk of low blood sugar (hypoglycaemia). If this happens, your doctor may need to adjust the dose of your other medicines.

Tell your doctor if you suffer from lactose intolerance.

VEXAZONE tablets contain lactose monohydrate.

If you have not told your doctor about any of the above, tell him/her before you start taking VEXAZONE.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from a pharmacy, supermarket or health food shop.

Some medicines and VEXAZONE may interfere with each other. These include:






oral contraceptives




These medicines may be affected by VEXAZONE or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking this medicine.

How to take VEXAZONE

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 pack, ask your doctor or pharmacist for help.

How much to take

The dose varies from person to person. Your doctor will decide the right dose for you.

The dose your doctor will prescribe for you will usually be in the range of 15 mg to 45 mg per day.


How to take it

Swallow the tablet whole with a glass of water.

When to take it

VEXAZONE must be taken once daily, 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 this medicine before or after food.

How long to take it

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

This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

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 it as soon as you remember, and then go back to your medicine as you would normally.

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

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 VEXAZONE. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

While you are taking VEXAZONE

Things you must do

It is important that you remember to take VEXAZONE daily and at the dose prescribed by your doctor.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking VEXAZONE.

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.

VEXAZONE may affect other medicines used during surgery.

If you become pregnant 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 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 have gained weight since taking this medicine.

Weight gain can be associated with improved blood sugar control; however, it may also be a symptom of heart failure.

Things you must not do

Do not take VEXAZONE 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.

If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects.

Things to be careful of

VEXAZONE alone is unlikely to affect your ability to drive or operate machinery. However, be careful not to let your blood glucose levels fall too low whilst driving or operating machinery if using VEXAZONE in combination with other anti-diabetic medicines.

If your blood glucose level becomes too low, you may feel dizzy, light headed, weak or tired and your reaction time may be slower than usual.

If you have any of these symptoms, do not drive or do anything else that could be dangerous.

Lifestyle measures that help reduce heart disease risk

By following these simple measures, you can further reduce the risk from heart disease.

Quit smoking and avoid second-hand smoke.

Limit alcohol intake.

Enjoy healthy eating by:

eating plenty of vegetables and fruit;

reducing your saturated fat intake (eat less fatty meats, full fat dairy products, butter, coconut and palm oils, most take-away foods, commercially-baked products).

Be active. Progress, over time, to at least 30 minutes of moderate-intensity physical activity on 5 or more days each week. Can be accumulated in shorter bouts of 10 minutes duration. If you have been prescribed anti-angina medicine, carry it with you when being physically active.

Maintain a healthy weight.

Discuss your lifestyle and lifestyle plans with your doctor.
