Quick answer
Ringworm (tinea corporis) is treated with an OTC antifungal cream applied twice daily to a 2 cm margin beyond the ring — clotrimazole 1% or miconazole 2% for 2–4 weeks, or terbinafine 1% for 1–2 weeks. Wash bedding and towels hot, treat pets that scratch, and don't share clothing. See a doctor for scalp ringworm (tinea capitis), widespread body involvement, or if the ring doesn't clear in 4 weeks — oral terbinafine or griseofulvin may be needed.

Ringworm treatment timeline
| Stage | What to do | What to expect |
|---|---|---|
| Days 1–3 | Start OTC antifungal cream | Redness and itching start to reduce. The ring edge is still visible. |
| Week 1 | Continue twice-daily application | The raised edge flattens; the centre skin lightens. Keep applying to a wide margin. |
| Weeks 2–4 | Finish the full course | Ring resolves. Discoloration (post-inflammatory pigmentation) may persist for weeks — this is not active infection. |
| Week 4+ | See a GP if unresolved or on scalp | Scalp ringworm and stubborn body ringworm need oral terbinafine or griseofulvin. A pet check-up may be needed if a household animal is the source. |

Home care to speed healing
- Cover the patch with a light dressing during sports or shared showers
- Wash towels, sheets, and clothing that touched the rash at 60 °C
- Don't share hairbrushes, hats, or sports gear until the rash is fully cleared plus 1 week
- Check other family members and pets for similar patches
- Keep fingernails short and avoid scratching — you can spread it to new sites

Full treatment plan
- OTC topical antifungal — terbinafine 1% once daily for 1–2 weeks OR clotrimazole/miconazole 1% twice daily for 4 weeks
- Apply about 2 cm beyond the visible edge — the fungus extends past what you can see
- Continue for 1 week AFTER the rash clears to prevent relapse
- Don't share towels; wash bedding and clothing in hot water
- Treat any infected pet — see a vet for their treatment
- See a doctor for oral antifungal if the rash is widespread, on the scalp/beard, or fails to clear in 4 weeks
When you need prescription treatment
Most cases clear in 2–4 weeks with OTC antifungal cream. Scalp ringworm always needs prescription oral treatment for 4–8 weeks. Recurrence is uncommon once the source (person, pet, sports mat) is treated.
See a doctor if:
- Scalp involvement (tinea capitis) — needs oral antifungal, not cream
- Widespread body rash or multiple large patches
- Bacterial superinfection (pus, spreading warm redness)
- No improvement after 4 weeks of correct OTC treatment
- Immunosuppressed patients — see a doctor early
Prevent re-infection
- Don't share towels, clothes, hats, or sports gear
- Shower after contact sports and wash mats between practices
- Have new pets checked by a vet if they have hair-loss patches
- Treat athlete's foot early — you can spread it to the body by hand
- Wash hands after touching an infected patch
Frequently asked questions
Frequently Asked Questions
No. Ringworm is a fungal infection — the name comes from the ring-shaped rash, not from any worm. It's caused by dermatophyte fungi that live on skin, hair, and nails.
Ringworm stops being contagious around 48 hours after starting a topical antifungal, and fully clears in 2–4 weeks. Scalp ringworm needs oral treatment and stays contagious longer. Wash bedding and towels at the start of treatment to prevent re-infection.
Terbinafine 1% cream (Lamisil AT and generic) cures most body ringworm with 1–2 weeks of once-daily application. Clotrimazole or miconazole are cheaper alternatives that work with a 4-week course. Apply about 2 cm beyond the visible rash edge — the fungus extends past what you can see.
Yes. Kittens are the most common source, followed by puppies, rabbits, and guinea pigs. If you have a ringworm rash and your pet has a hair-loss patch or crusty skin, take the pet to a vet — you'll re-infect each other until both are treated.
Only during contact sports or shared showers, and remove it at other times so the skin can dry. Occlusion keeps the area moist and can slow healing. Antifungal cream works best on open skin exposed to air.
See a GP if the rash covers a wide area, involves the scalp or beard, isn't clearing after 4 weeks of OTC treatment, or if you're immunosuppressed. Oral antifungal (terbinafine or griseofulvin) may be needed — especially for scalp involvement.
