How effective is treating ring worm with lotrisone (clotrimazole and betamethasone)?

Not ideal: If you have been definitively diagnosed with "ring worm" (a form of dermaphytosis), then lotrisone (clotrimazole and betamethasone) is not an ideal therapy. This is because this medicine contains a topical corticosteroid, which does not actually treat the fungal infection (it may help relieve the itch) as well as an anti-fungal. The latter is all you really need. A single anti-fungal agent suffices.
