Triterpenoid antifungals are used to treat vaginal yeast infections. These medications work by interfering with how yeast make their protective cell wall, which helps to kill the fungus and stop the infection. Triterpenoid antifungals are available as oral tablets. An example of a triterpenoid antifungal is Brexafemme (ibrexafungerp). You can take these medications to help control vaginal yeast infections.
