Uses for micafungin

Micafungin injection is used to treat fungal infections, including candidemia, acute disseminated candidiasis (fungal infection in the blood), candida peritonitis and abscess (fungal infection in the stomach), and esophageal candidiasis (fungal infection in the esophagus). This medicine is also used to prevent candida infections in patients who have a weakened immune system (eg, hematopoietic stem cell transplant). It is also used to treat candida peritonitis and abscess (fungal infection in the stomach) without meningoencephalitis or ocular dissemination.

This medicine is to be given only by or under the direct supervision of your doctor.

Pediatric

However, safety and efficacy of micafungin injection have not been established for the treatment of candidemia with meningoencephalitis or ocular dissemination, esophageal candidiasis, and to prevent candida infections with stem cell treatment in children younger than 4 months of age.
