What is Itraconazole?
Itraconazole is an antifungal medicine. The active ingredient itraconazole works by weakening the cell membranes of various fungi and yeasts. These cell membranes are vital for their survival. Itraconazole treats fungal and yeast infections from the inside out: the medicine is absorbed in the bloodstream via the intestines and deposited in the affected tissues. Itraconazole is a prescription-only medicine.
What is Itraconazole used for?
Itraconazole is used to treat various infections with fungi and yeasts, including:
- Fungal infection of the foot (athlete’s foot);
- Tinea versicolour, Tinea corporis and other skin infections;
- Onychomycosis (fungal nail);
