How to Treat Ringworm That Won't Go Away

Ringworm is a contagious infection that develops after tinea, a common fungus, begins to grow on your body. You can acquire tinea from an infected person or animal, and also if your skin is exposed to damp contaminated surfaces. Ringworm gets its name from the circular, raised appearance of the ringworm rash; it is not caused by a worm, according to the American Academy of Family Physicians 2. Most people can eliminate ringworm with over-the-counter anti-fungal creams, but ringworm that does not respond to these medications requires more aggressive treatment.

See your doctor. If you have attempted to treat your ringworm for two to four weeks without success, medical treatment with a prescription anti-fungal cream or an oral anti-fungal medication is necessary.

Apply prescription anti-fungal cream to your ringworm rash as your doctor directs. Doctor-prescribed topical medications are stronger than over-the-counter creams, and they may be effective on your tough case of ringworm.

Talk to your doctor about oral anti-fungal medications. These prescription medicines are reserved for fungal infections that have been resistant to other treatments. Ringworm will usually respond quickly to anti-fungal pills, according to the U.S. National Library of Medicine.
