What this medicine is used for

The name of your medicine is Voriconazole APOTEX powder for injection. It contains the active ingredient voriconazole.

It is used to treat fungal and yeast infections such as:

  • invasive aspergillosis (as-pur-ji-lo-sis), a fungal infection caused by a fungus called Aspergillus (as-pur-ji-lus), which usually begins in the respiratory tract (in the nose, sinuses or lungs). Aspergillus is harmless in most healthy people; however, in people with poor immune systems (such as people who have had organ transplants and people with cancer or HIV/AIDS), invasive aspergillosis can be serious and spread to other tissues and organs.
  • serious Candida (can-di-da) infections, including those that have spread into the blood stream or to other parts of the body.
  • serious fungal infections caused by Scedosporium (ski-doe-spore-ri-um) species and Fusarium (few-saa-ri-um) species.
  • other serious fungal infections in patients who do not respond to, or cannot tolerate, other antifungal medicines.

Voriconazole is also used to prevent invasive fungal infections in patients who are at risk of developing such infections.

Ask your doctor if you have any questions about why this medicine has been chosen for you. Your doctor may have given you this medicine for another reason.
