Micafungin Injection

Why is this medication prescribed?

Micafungin is used to treat certain fungal infections that have caused esophagitis ( infection of the throat), spread to the bloodstream, have caused abscesses (collection of pus in body tissue) or caused peritonitis (infection of the lining of the stomach) in adults and children. It is also used to prevent fungal infections in adults and children who have undergone a hematopoietic stem cell transplant (HSCT; procedure in which certain blood cells are removed from the body and then returned to the body). Micafungin is in a class of medications called echinocandins. It works by stopping the building of cell walls in the fungus causing it to die.

How should this medicine be used?

Micafungin injection comes as a powder to be mixed with a liquid and given intravenously (into the vein). It is usually given once a day. Your doctor will decide how long you should receive micafungin.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
