Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking Diflucan IV.

Receiving Diflucan IV

Diflucan IV can only be given by a doctor or nurse. It is usually infused slowly into a vein.

Usual dose

The amount of Diflucan IV you receive, and the length of your treatment, will depend on your body weight and kidney function. It will also depend on how quickly the infection is brought under control.

After a while, the injection may be stopped and you may begin to receive Diflucan capsules or oral suspension by mouth.

If you are given too much (overdose)

Because Diflucan IV is given to you by a health professional, overdose is unlikely to arise.

While you are receiving it
