What is the initial management for a patient presenting with erythema nodosum (Nonsteroidal Anti-Inflammatory Drugs (NSAIDs))?

From the Guidelines

The initial management for a patient presenting with erythema nodosum includes nonsteroidal anti-inflammatory drugs (NSAIDs) as first-line therapy. When considering the management of erythema nodosum, it's crucial to prioritize morbidity, mortality, and quality of life as outcomes. The most recent and highest quality study, although not directly focused on erythema nodosum, provides insight into the management of related inflammatory conditions 1. Given the information available, NSAIDs such as ibuprofen (400-800 mg three times daily) or naproxen (500 mg twice daily) are typically recommended for symptom relief in erythema nodosum, as they target the underlying inflammatory process by inhibiting cyclooxygenase enzymes, thereby reducing prostaglandin synthesis which mediates pain and inflammation. Key points to consider in the management of erythema nodosum include:

• The use of NSAIDs with food to minimize gastrointestinal side effects
• Treatment duration of 1-2 weeks or until symptoms resolve
• Alternative use of acetaminophen (500-1000 mg every 6 hours, not exceeding 4000 mg daily) for patients with NSAID contraindications
• Supportive measures like bed rest and elevation of the affected limbs to reduce pain and swelling
• Simultaneous investigation and addressing of any underlying causes of erythema nodosum, such as infections, medications, or systemic diseases, for definitive management. It's also important to note that while NSAIDs are the first line of treatment, systemic corticosteroids may be required in severe cases, and relapsing or resistant forms can be treated with immunomodulators or anti-TNF, as suggested by the European evidence-based consensus on extra-intestinal manifestations in inflammatory bowel disease 1.

From the FDA Drug Label

NSAIDs can cause serious side effects, including: Increased risk of a heart attack or stroke that can lead to death Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus (tube leading from the mouth to the stomach), stomach and intestines

The initial management for a patient presenting with erythema nodosum using Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), such as ibuprofen, includes:

• Monitoring for signs and symptoms of GI ulceration and bleeding during NSAID therapy
• Discontinuation of the NSAID until a serious GI adverse event is ruled out
• Considering alternate therapies that do not involve NSAIDs for high-risk patients
• Using the lowest effective dose for the shortest possible duration
• Patients and physicians should remain alert for signs and symptoms of GI ulcerations and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI event is suspected 2. Key considerations for patients with erythema nodosum taking NSAIDs include:
• GI risks: Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus, stomach, and intestines
• Cardiovascular risks: Increased risk of a heart attack or stroke that can lead to death
• Renal effects: Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury
• Skin reactions: NSAIDs can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal 2 3.

From the Research

Initial Management of Erythema Nodosum

The initial management of erythema nodosum involves treating the symptoms and identifying the underlying cause.

• Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) such as aspirin, oxyphenbutazone, indomethacin, or naproxen may be helpful in enhancing analgesia and resolution 4, 5, 6, 7.
• Bed rest and leg elevation are generally recommended to reduce discomfort 4, 7.
• Potassium iodide may also be used as a treatment option 4, 6.

Things to Watch Out For

When managing erythema nodosum, it is essential to:

• Identify and treat the underlying cause, if possible 4, 5, 8, 6, 7.
• Rule out underlying infections before administering systemic corticosteroids 4, 5.
• Be aware of the potential for erythema nodosum to be a cutaneous manifestation of a systemic disease 8, 7.
• Consider a diagnostic algorithm to optimize the initial work-up and initiate prompt and accurate management of the underlying disease 8.

Treatment Options

Treatment options for erythema nodosum include:

• NSAIDs for pain management 4, 5, 6, 7.
• Potassium iodide 4, 6.
• Colchicine 6.
• Systemic corticosteroids, although rarely indicated and only after ruling out underlying infections 4, 5.
