Where to find information in this leaflet:
1. Why am I using VTTACK?
VTTACK contains the active ingredient voriconazole. VTTACK belongs to a group of medicines called triazole antifungals. This medicine
works by preventing the growth of fungal and yeast organisms causing your infection.
VTTACK is used to treat fungal and yeast infections such as:
invasive aspergillosis (as-pur-ji-losis), a fungal infection caused by a fungus called
Aspergillus (as-pur-jilus), 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-did-da) infections, including Candida infections of the oesophagus
(food pipe or gullet) and those that have spread into the blood stream or to other
parts of the body.
serious fungal infections caused by Scedosporium (ski-doe-spore-rium) species and
Fusarium (few-saa-rium) species.
other serious fungal infections in patients who do not respond to, or cannot tolerate,
other antifungal medicines.
VTTACK is also used to prevent invasive fungal infections in patients who are at risk
of developing such infections.
