What Diflucan is used for
Diflucan capsules (for adults) and oral suspension (for children) are used to treat certain fungal and yeast infections.
Diflucan belongs to a group of medicines called azole antibiotics.
It works by preventing the growth of the fungal and yeast organisms causing your infection.
Ask your doctor if you have any questions about why Diflucan has been prescribed for you. Your doctor may have prescribed Diflucan for another reason.
Diflucan is available only with a doctor's prescription.
This medicine is not addictive.

How to take Diflucan
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box or bottle, ask your doctor or pharmacist for help.
How much to take
The dose will depend on your infection and how you respond to Diflucan. It usually ranges from 50 mg to 400 mg once daily.
The dose for a child will depend on body weight and usually ranges from 3 mg to 12 mg per kilogram of body weight. In very young children (below 4 weeks of age), Diflucan is usually given every second or third day.
However, depending on how serious the infection is, and how you react to the medicine, your doctor may ask you to take a different dose.
How to take it
Swallow the capsules whole with water.
Shake the bottle well and accurately measure the dose with a medicine measure. Only take it by mouth.
When to take it
Try to take your medicine 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 to 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 Diflucan until you finish the pack or bottle or until your doctor recommends. The length of time you take Diflucan will depend on the sort of infection you have.
Patients with a weakened immune system or those with difficult infections may need long-term treatment to prevent the infection from returning.
Do not stop taking your Diflucan because you are feeling better. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
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, then go back to taking it as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you take too much (overdose)
Immediately telephone your doctor or the National Poisons Information Centre (telephone Australia 13 11 26; New Zealand 0800 POISON or 0800 764 766) for advice if you think you or anyone else may have taken too much Diflucan. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
While you are taking it
Things you must do
If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.
If you are a woman of child-bearing age, you should avoid becoming pregnant while taking Diflucan.
If you do become pregnant while taking Diflucan, tell your doctor immediately.
If you are about to be started on any new medicine, remind your doctor or pharmacist that you are taking Diflucan.
Tell any other doctors, dentists and pharmacists who treat you that you are taking Diflucan.
Things you must not do
Do not stop taking Diflucan or lower the dosage without checking with your doctor. If you do not complete the full course prescribed by your doctor, all of the organisms causing your infection may not
be killed. These organisms may continue to grow and multiply so that your infection may not clear completely or may return.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not use Diflucan to treat any other medical complaints unless your doctor tells you to.
Things to be careful of
Be sure to follow your doctor's advice if regular checks on your liver are recommended. In rare cases, Diflucan may affect the liver and may need to be stopped.
If you suffer from HIV or have a weakened immune system and develop a rash while taking Diflucan, tell your doctor immediately. If this rash worsens, Diflucan may need to be stopped.
Be careful when driving vehicles or operating machinery as occasional dizziness or seizures may occur.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Diflucan.

After using Diflucan
Keep your medicine in its original pack until it is time to take it. If you take it out of the pack it may not keep well.
Keep Diflucan capsules and oral suspension in a cool, dry place where the temperature stays below 30°C.
Do not store your medicine in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.
Keep your medicine 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.
