VORISPORE is an antifungal medicine. It works by killing or stopping the growth of the fungi that cause infections. VORISPORE is used for the treatment of a wide variety of fungal infections in patients (adults and children over the age of 2). VORISPORE may also be used for the prevention of fungal infections in high risk bone marrow transplant recipients.

3. How VORISPORE will be given to you
VORISPORE should only be used under the supervision of a doctor. You will not be expected to give yourself VORISPORE. It will be given to you by a person who is qualified to do so. Your doctor will decide what dose (depending on your weight) you should receive for your condition and also for how long you need to receive it. The dose and duration of treatment will depend on how your body and the infection reacts on the treatment. Usually you will be given 6 mg VORISPORE per kg body mass, every 12 hours for the first 24 hours and thereafter 4 mg/kg every 12 hours as maintenance dose. If you use efavirenz (for HIV) or phenytoin (anti-seizure medicine), your doctor may adapt your dosage. See “Other medicines and VORISPORE”. Your doctor or other healthcare provider will give you VORISPORE through a slow infusion (a drip for 1 to 2 hours) into one of your large veins. Before it is used, VORISPORE powder for solution for infusion will be reconstituted and diluted to the correct concentration by your hospital pharmacist or nurse. You may be switched from the intravenous infusion to tablets once your condition improves.
