What Daonil is used for
Daonil is used to control blood glucose levels in patients with type 2 diabetes mellitus. This type of diabetes is also known
as non-insulin-dependent diabetes (NIDDM) or maturity 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 glucose by increasing the amount of insulin released by your pancreas.
Daonil belongs to a group of medicines called sulphonylureas.
If your blood glucose is not properly controlled, you may experience hypoglycaemia (low blood glucose) or hyperglycaemia (high
blood glucose). High blood glucose can lead to serious problems with your heart, eyes, circulation or kidneys.
Low blood glucose can occur suddenly. Signs may include:
weakness, trembling, shaking
light headedness, dizziness, headache or lack of concentration
tearfulness, crying or depression
numbness around the lips and tongue
restlessness or disturbed sleep
If not treated promptly, these may progress to:
loss of co-ordination
loss of consciousness or seizures
High blood glucose usually occurs more slowly than low blood glucose. Signs of high blood glucose may include:
lethargy or tiredness
passing large amounts of urine and more often
dry mouth or dry skin
Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Daonil is not addictive.

When to take it
Take your tablet immediately before breakfast. If you only eat a very light breakfast, then this dose should be put off until
Do not skip meals whilst using Daonil. Take your dose at the same time each day.
How long to take it
Continue taking Daonil for as long as your doctor tells you.
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
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 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 that 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 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 Daonil. Do this even if there
are no signs of discomfort or poisoning.
If you take too much Daonil you may experience symptoms of hypoglycaemia (low blood sugar).
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.
While you are using Daonil
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Daonil.
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.
It may affect other medicines used during surgery.
If you become pregnant while taking Daonil, tell your doctor immediately.
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 glucose 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 eg. plain biscuits,
fruit or milk - when over the initial symptoms. Taking this extra carbohydrate will prevent a second drop in your blood glucose
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
If you experience any of the signs of high blood glucose (hyperglycaemia), contact your doctor immediately.
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
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 Daonil.
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.
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 heart beat, stomach
pains or feel sick and vomit.
Tell your doctor immediately if you 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
Things you must not do
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 stop taking your medicine or lower the dosage without checking with your doctor.
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 have to be alert, for example when driving, be especially 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. Drinking alcohol
can make this worse. However, Daonil by itself is unlikely to affect how you drive or operate machinery.
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 eg. sugar sachets or jelly beans
carry emergency food rations in case of a delay eg. dried fruit, biscuits or muesli bars
keep some Daonil readily available
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.
Tell your doctor, or pharmacist as soon as possible if you do not feel well while you are taking Daonil.
