Daonil®

Active ingredient(s): glibenclamide

Consumer Medicine Information (CMI)

This leaflet provides important information about using Daonil. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using Daonil.

Where to find information in this leaflet:

1. Why am I taking Daonil?

Daonil contains the active ingredient glibenclamide.

Daonil belongs to a group of medicines called sulphonylureas.

Daonil is used to control blood sugar levels in patients with type 2 diabetes mellitus.

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

Daonil is used in conjunction with diet control and exercise to control blood sugar.

Daonil can be used alone, or in combination with insulin or other anti-diabetes medicines.

Daonil lowers high blood sugar by increasing the amount of insulin released by your pancreas.

If your blood sugar is not properly controlled, you may experience hypoglycaemia (low blood sugar) or hyperglycaemia (high blood sugar). High blood sugar can lead to serious problems with your heart, eyes, circulation or kidneys.

Low blood sugar can occur suddenly. Signs may include:

• weakness, trembling, shaking
• sweating
• light headedness, dizziness, headache or lack of concentration
• tearfulness, crying or depression
• irritability
• hunger
• numbness around the lips and tongue
• restlessness or disturbed sleep.

If not treated promptly, these may progress to:

• loss of co-ordination
• slurred speech
• confusion
• loss of consciousness or seizures.

High blood sugar usually occurs more slowly than low blood sugar. Signs of high blood sugar may include:

• lethargy or tiredness
• headache
• severe thirst
• passing large amounts of urine and more often
• blurred vision
• dry mouth or dry skin.

Daonil is not addictive.

2. What should I know before I take Daonil?

4. How do I take Daonil?

How much to take

• Your doctor will tell you how many tablets to take each day. Your doctor may increase or decrease the dose depending on your blood sugar levels.
• Follow the instructions provided and take Daonil until your doctor tells you to stop.

This medicine helps to control your diabetes, but will not cure it. Therefore, you may have to take it for a long time. It is important to keep taking your medicine even if you feel well. Make sure you have enough Daonil to last over weekends and holidays.

When to take Daonil

• Daonil should be taken immediately before breakfast. If you only eat a very light breakfast, then this dose should be put off until lunchtime.

Do not skip meals whilst using Daonil.

Take your dose at the same time each day.

How to take Daonil

Swallow the tablets with a full glass of water.

If you forget to take Daonil

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 taking your medicine as you would normally.

Missed doses can cause high blood sugar (hyperglycaemia).

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

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

If you are not sure what to do, ask your doctor, pharmacist or diabetes educator.

If you have trouble remembering to take your medicine, ask your doctor, pharmacist or diabetes educator for some hints.

If you take too much Daonil

If you think that you have taken too much Daonil, you may need urgent medical attention.

You should immediately:

• phone the Poisons Information Centre
• (by calling 13 11 26 in Australia or 0800 764 766 in New Zealand), or
• contact your doctor, or
• go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

If you take too much Daonil you may experience symptoms of low blood sugar (hypoglycaemia).

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

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

If you experience any of the symptoms of an overdose, immediately get medical help.

5. What should I know while taking Daonil?

Things you should do

Make sure you, your friends, family and work colleagues can recognise the symptoms of hypoglycaemia and hyperglycaemia and know how to treat them.

If you experience any of the symptoms of low blood sugar (hypoglycaemia), you need to raise your blood sugar urgently. You can do this by taking one of the following:

• 5 - 7 jelly beans
• 3 teaspoons of sugar or honey
• 1/2 can of ordinary (non-diet) soft drink
• 2-3 concentrated glucose tablets.

Unless you are within 10 to 15 minutes of your next meal or snack, follow up with extra carbohydrates e.g. plain biscuits, fruit or milk - when over the initial symptoms. Taking this extra carbohydrate will prevent a second drop in your blood sugar level.

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

The risk of hypoglycaemia is also increased in the following situations:

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

Tell your doctor if you:

• become ill
• experience extra stress
• are injured
• have a fever
• have a serious infection
• need surgery.

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

Make sure you check your blood sugar 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.

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

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

If you drink alcohol while taking Daonil, you may get flushing, headache, breathing difficulties, rapid heartbeat, stomach pains or feel sick and vomit.

Call your doctor straight away if you:

• become pregnant
• notice the return of any symptoms you had before starting Daonil.

These may include lethargy or tiredness, headache, thirst, passing large amounts of urine and blurred vision. These may be signs that Daonil is no longer working effectively, even though you may have been taking it successfully for some time.

• experience any of the signs of high blood sugar (hyperglycaemia).

The risk of hyperglycaemia is increased in the following situations:

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

Remind any doctor, dentist, pharmacist, or diabetes educator you visit that you are taking Daonil.

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

Things you should not do

• Do not stop taking this medicine or lower the dosage without checking with your doctor.
• Do not take Daonil 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 skip meals while taking Daonil.

Things to be careful of

Protect your skin when you are in the sun, especially between 10am and 3pm.

Daonil may cause your skin to be more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness or severe sunburn.

If outdoors, wear protective clothing and use a highly effective sunscreen.

If you experience sunburn, tell your doctor immediately.

If you become sick with a cold, fever or flu, it is very important to continue taking Daonil. 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.

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 if it occurs e.g. sugar sachets or jelly beans
• carry emergency food rations in case of a delay e.g. dried fruit, biscuits or muesli bars
• keep some Daonil readily available.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how Daonil affects you.

This medicine is not expected to affect your ability to drive a car or operate machinery.

If you have to be alert, for example when driving, be especially careful not to let your blood sugar levels fall too low.

Low blood sugar levels may slow your reaction time and affect your ability to drive or operate machinery. Drinking alcohol can make this worse. However, Daonil by itself is unlikely to affect how you drive or operate machinery.

Drinking alcohol

Tell your doctor if you drink alcohol.

Alcohol may:

• lead to low blood sugar (hypoglycaemia) by increasing the blood sugar lowering effect of Daonil
• lead to high blood sugar (hyperglycaemia) by weakening the blood sugar lowering effect of Daonil
• hide the symptoms of low blood sugar.

Looking after your medicine

• Store the tablets below 25°C. Protect from light.
• Keep your tablets in the carton until it is time to take them.

If you take the tablets out of the carton they may not keep well.

Follow the instructions in the carton on how to take care of your medicine properly.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

• in the bathroom or near a sink, or
• in the car or on window sills.

Heat and dampness can destroy some medicines.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine

If you no longer need to take this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not take this medicine after the expiry date printed on the carton 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.
