Micafungin, sold under the brand name Mycamine, is an echinocandin antifungal medication used to treat and prevent invasive fungal infections including candidemia, abscesses, and esophageal candidiasis. It inhibits the production of beta-1,3-glucan, an essential component of fungal cell walls that is not found in mammals.

Administered intravenously, Micafungin received final approval from the U.S. Food and Drug Administration (FDA) in March 2005, and gained approval in the European Union in April 2008. It is on the World Health Organization's List of Essential Medicines.[1]

In August 2023, Mycamine was acquired from Astellas Pharma by Sandoz.[2]
