How do you treat ringworm?
Last updated September 3, 2026.
A pharmacy antifungal cream, gel, or spray (clotrimazole or terbinafine), used daily for up to 4 weeks - including after the rash looks gone - treats most ringworm. The fungus outlasts the visible rash, so early stopping is why it returns. Contain it while treating: no shared towels, clothes, or bedding; wash hands after touching it; hot-wash sheets; check pets for bald patches, since cats and dogs are classic sources. See a doctor instead of self-treating for scalp or beard ringworm (prescription tablets needed), large or multiple patches, immune suppression, or no clear improvement after two weeks. Pymander is a free AI doctor, 24/7 by text, and can help you tell ringworm from look-alikes like eczema.
What to do
- Start an antifungal cream today: clotrimazole or terbinafine from any pharmacy.
- Finish the full course: up to 4 weeks, even after it clears.
- Stop the spread: own towel, hot-washed bedding, hand-washing after contact.
- Check the pets: a cat or dog with a bald patch is often the source.
