Erythema Nodosum
Treatment of Erythema Nodosum
Leg elevation and cool compresses Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain Treatment of underlying disorders Erythema nodosum almost always resolves on its own, and the nodules usually go away in 3 to 6 weeks without treatment. Bed rest, cool compresses, elevation of the legs, and nonsteroidal anti-inflammatory drugs may help relieve the pain caused by the nodules.Potassium iodidetablets may be given to decrease inflammation. Corticosteroids taken by mouth are effective but are given only as a last resort because they can worsen an underlying infection even if one has not been identified. Drugs that might be causing erythema nodosum are stopped, and any underlying infections or disorders are treated. If the disorder is caused by a streptococcal infection, a person may have to take antibiotics, such as penicillin, or a cephalosporin.
