ABOUT THIS MEDICATION
What the medication is used for:
Your doctor has prescribed Micafungin Sodium for Injection to treat one of several types of fungal infections described below.
- Micafungin Sodium for Injection is used to treat certain fungal infections of the esophagus (food tube connecting the mouth to the stomach).

Micafungin Sodium for Injection has not been studied for the treatment of other types of fungal infections.
What it does:
Micafungin Sodium for Injection is an antifungal drug that belongs to a class of drugs called echinocandins.

Fungal cells exposed to Micafungin Sodium for Injection have incomplete or defective cell walls, making them fragile and unable to grow.
