What should you know about oral ringworm treatment for cats?

Ringworm is caused by fungi that live in hair, skin, and claws; it is not a worm. Cats may have circular hair loss, broken hairs, crusting, scaling, or itch, but some carry the fungus with few visible signs. A veterinarian may use examination, a Wood’s lamp, microscopic hair review, or fungal testing to distinguish it from allergy, parasites, or other causes of a rash. The infection can pass between animals and people through direct contact or contaminated bedding, brushes, and surfaces.

Book a veterinary appointment and give every medicine only as directed. Oral antifungal treatment may be selected when infection is extensive, persistent, or involves areas that topical care cannot adequately reach. Topical antifungal treatment can reduce fungal material on the coat and skin, while clipping, bathing, or environmental cleaning may be advised for selected cats. Wash hands after handling the cat, separate grooming items, launder bedding, and vacuum hair and flakes from commonly used areas. Do not give human antifungal tablets or creams without veterinary instruction.

Seek prompt veterinary advice if lesions spread, the cat stops eating, seems unusually tired, develops eye or mouth involvement, or a kitten, older cat, or immunocompromised animal is affected. Contact a doctor if a household member develops an itchy or scaly skin rash after contact. Follow-up may be needed because visible improvement does not always mean fungal material has cleared.

Ask how the diagnosis will be confirmed, whether other pets need examination, how to give the oral medicine, what adverse signs to watch for, how to clean the home, and when testing or follow-up should occur.
