Posaconazole Injection

Posaconazole injection is used to prevent serious fungal infections that can spread throughout the body in adults and children 2 years of age and older with a weakened ability to fight infection. Posaconazole injection is also used to treat invasive aspergillosis (a serious fungal infection that begins in the lungs and spreads through the bloodstream to other organs) in adults and teenagers 13 years of age and older. Posaconazole injection is in a class of medications called azole antifungals. It works by slowing the growth of fungi that cause infection.

Posaconazole injection comes as a liquid to be injected intravenously (into a vein). It is usually infused (injected slowly) over 30 to 90 minutes twice daily on the first day and then once a day.
