Itrafungol Solution Antifungal for Oral Use in Cats
Itrafungol is a prescription antifungal liquid used to treat ringworm in cats. Despite the name, ringworm isn't a worm at all — it's a fungal skin infection that causes patchy hair loss, scaly or crusty skin, and itching, and it spreads easily between cats and to people. Itrafungol is FDA-approved to treat ringworm caused by Microsporum canis, the most common culprit in cats. It comes as a ready-to-use, slightly yellow liquid containing 10 mg of itraconazole per mL, with a graduated syringe included so you can measure your cat's dose precisely — no pill-hiding required. What to expect A "week on, week off" schedule. The typical course is once-daily dosing during weeks 1, 3, and 5, with no medication given during weeks 2 and 4. The off weeks are intentional, not a break in treatment — itraconazole builds up in the skin and coat and keeps fighting the infection between doses. Easy to give. It can be given with or without food. Measured by weight. Your veterinarian will calculate the exact dose for your cat. Cats over 13 lbs may need the dose split into two syringes. Finish the full course. Ringworm can look resolved on the surface before the fungus is fully cleared, so complete every treatment week as prescribed. Safety notes For cats only. Wash your hands after handling. Not for cats with a known sensitivity to itraconazole; hasn't been shown safe in pregnant or nursing cats; use with caution in cats with liver or kidney problems. Tell your vet about any other medications or supplements your cat is taking. Store at room temperature (68–77°F).
