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
Common questions
How do you treat ringworm?
Despite the name, ringworm is a fungal skin infection - no worm involved - and the tell is a round or oval patch with a raised, scaly, redder edge and clearer center that slowly expands. Treatment is a pharmacy antifungal cream, gel, or spray (clotrimazole or terbinafine), applied daily for up to 4 weeks - and here is the part people get wrong: keep using it for the full course even after the rash looks gone, because the fungus outlasts the visible rash and stopping early is why it returns. While treating, contain it: ringworm spreads by skin contact and shared items, so wash hands after touching the patch, do not share towels, clothing, or bedding, wash sheets and clothes hot, and keep kids home from school or sports until treatment is underway. Check pets - cats and dogs are a classic source, and a pet with a bald patch needs a vet. See a doctor rather than self-treating if it is on the scalp or beard (those need prescription tablets), covers a large area, involves several patches, is in someone with a weak immune system, or is not clearly better after two weeks of cream.
