Treatments Your Provider May Prescribe
In order to confirm the diagnosis of ringworm, your physician might scrape some surface skin material (scales) onto a slide and examine them under a microscope. This procedure, called a KOH (potassium hydroxide) preparation, allows the doctor to look for tell-tale signs of fungal infection.
Once the diagnosis of ringworm has been confirmed, your physician will likely start treatment with an antifungal medication. Most infections can be treated with prescription-strength topical creams and lotions, including:
- Terbinafine
- Clotrimazole
- Miconazole
- Econazole
- Oxiconazole
- Ciclopirox
- Ketoconazole
- Sulconazole
- Naftifine
- Butenafine
Rarely, more extensive infections or those not improving with topical antifungal medications may require 3–4 weeks of treatment with oral antifungal pills, including:
- Terbinafine
- Itraconazole
- Griseofulvin
- Fluconazole
- Ketoconazole
The ringworm should go away within 4–6 weeks after using effective treatment.
