What is the best inexpensive cream that treats ringworm?

Lotrimin is an effective over-the-counter topical cream that treats ringworm, athlete's foot, jock itch and other variants of skin fungus, states WebMD. Lotrimin is available under the generic name clotrimazole.

Lotrimin should be used under the direction of a doctor, and the full course should be completed even if the patient experiences relief earlier, according to Drugs.com. Stopping the medication too early can lead to the infection returning. The cream should be applied to clean, dry skin in a thin, uncovered layer. Patients should consult their doctor prior to using Lotrimin if they are pregnant, breastfeeding or taking any other medications.
