4. How is Diflucan given?

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 once daily. 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.

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 to take it


Swallow the capsules whole with water.

Oral Suspension:

Shake the bottle well and accurately measure the dose with a medicine measure. Only take it by mouth.

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

Diflucan should be used as prescribed. If you miss your dose at the usual time, please see the following instructions.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

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

Otherwise, take it as soon as you remember, then go back to taking it as you would normally.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or
