First-Line Treatment of Primary Erythema Nodosum

Primary erythema nodosum presents as erythematous nodules, typically on the pretibial area. The condition is generally self-limited, with most cases resolving within 1–6 weeks with appropriate symptomatic management.

The primary clinical aims are resolution of erythematous nodules on the pretibial area within 1–6 weeks, together with relief of pain and edema in the lower extremities.

Symptomatic and supportive care is adequate for most patients. The first-line approach includes physical measures directed at lower-limb edema and discomfort, alongside an oral anti-inflammatory agent for pain control.

The complete regimen — specific agents, sequencing, and monitoring guidance — is available in the full structured protocol below.
