Treatment of Ringworm
The recommended first-line treatment for ringworm (tinea corporis) is topical antifungal therapy with agents such as clotrimazole 1% cream or miconazole 2% cream applied twice daily for 2-4 weeks. 1
Topical Treatment Options
- Clotrimazole 1% cream applied twice daily for 2-4 weeks is an effective first-line treatment for ringworm 1, 2
- Miconazole 2% cream applied twice daily for 2-4 weeks is another effective first-line option 1, 2
- Terbinafine and naftifine topical formulations have shown superior efficacy compared to placebo in clinical studies 2
- Treatment should continue until clinical resolution of symptoms, typically 2-4 weeks for tinea corporis 2, 3
Oral Treatment Options

- Griseofulvin is FDA-approved for dermatophyte infections including tinea corporis at a dosage of:

Special Considerations
- Accurate diagnosis is essential before initiating treatment - identification should be made by direct microscopic examination with potassium hydroxide (KOH) preparation or culture 5, 3
- For ringworm in areas with skin folds or widespread infection, oral antifungal therapy may be more appropriate than topical treatment 4
- General hygiene measures should be observed to control sources of infection or reinfection 5
- If no improvement is seen after 2 weeks of appropriate therapy, consider switching to a different class of antifungal agent 1
- Treatment should continue for at least one week after clinical clearing of infection to prevent relapse 3
Monitoring and Follow-up
- Clinical response should be evident within 1-2 weeks of starting appropriate therapy 2
- Treatment failure may indicate incorrect diagnosis, non-adherence to treatment, or rarely, antifungal resistance 2
- For extensive or chronic infections, follow-up evaluation is recommended to confirm complete resolution 4
