Antithyroid agents

Antithyroid agents relieve lesional tenderness, arthralgia, and fever. Relief may occur within 24 hours. Most lesions completely subside within 10-14 days. Potassium iodide is not effective for all patients with erythema nodosum. Patients who receive medication shortly after the initial onset of erythema nodosum respond more satisfactorily than patients with chronic erythema nodosum.

Potassium iodide (Pima, SSKI)

The mechanism of action for potassium iodide in erythema nodosum is unknown, but it is known to enhance response by potentiating neutrophil activity.
