What should you know about feline ringworm treatment?

Ringworm is a fungal infection of the outer skin, hair, or nails. Treatment depends on the body site, the number and size of patches, and whether hair-bearing areas or nails are involved. A clinician may recommend topical antifungal treatment for limited skin disease, while oral antifungal treatment can be considered when infection is extensive, recurrent, or affects hair or nails. A cat can remain a source of spores, so human treatment works best alongside veterinary diagnosis and management.

Use the prescribed medicine exactly as directed and keep using it for the advised course, even if redness and itching settle early. Keep the area clean and dry, wash hands after touching the rash or cat, and avoid sharing towels, clothing, brushes, and bedding. Launder washable fabrics and clean surfaces that collect shed hair. Never substitute a veterinary medicine for a human prescription. If the diagnosis is uncertain, ask for confirmation before applying a steroid cream alone, because steroids can alter the appearance of a fungal rash.

Arrange a review if the rash continues to enlarge, new patches appear, treatment irritates the skin, or there is no clear improvement with the advised plan. Seek prompt care for scalp involvement, nail changes, pus, marked pain, fever, or facial or eye symptoms. People with reduced immunity and young children should be assessed early after a possible exposure.

Ask which treatment is suitable for the affected site, whether testing is needed, how to handle missed applications, when the cat and household should be rechecked, and which cleaning measures are realistic for your home.
