Erythema nodosum

Treatment:

The underlying infection or drug must be identified and treated. Nonsteroidal anti-inflammatory medications (NSAIDs) may reduce symptoms. Occasionally, oral potassium iodide (SSKI) solution may produce prompt resolution of the nodules. Corticosteroids or salicylate medications may be needed to reduce acute inflammation. Analgesics and limitation of activity may be needed to control varying amounts of pain. Topical therapy is not generally needed, although hot or cold compresses may reduce discomfort.

Expectations (prognosis):

Erythema nodosum is uncomfortable but not usually dangerous to the health. Symptoms usually disappear within about 6 weeks but may recur.

Complications:

Aside from possible recurring symptoms, there are no complications.

Calling your health care provider:

Call for an appointment with your health care provider if symptoms of erythema nodosum develop.
