From the Guidelines
Corticosteroids, specifically prednisolone, are the drug of choice for managing erythema nodosum leprosum (ENL) in leprosy (Hansen's disease) [no relevant evidence provided].
Treatment Approach
- The dose of prednisolone is typically 1-2 mg/kg/day [@not available@], which is administered for 2-4 weeks, followed by a gradual tapering of the dose over 2-3 months.
- In severe cases, Clofazimine may be added as an adjunct therapy at a dose of 300 mg/day [@not available@].
- Thalidomide is reserved for severe, corticosteroid-resistant cases, due to its potential side effects [@not available@].
Important Considerations
- The provided evidence does not support the use of Colchicine as the first-line treatment for ENL, despite its mention in the context of erythema nodosum in other diseases 1.
- The treatment approach should be tailored to the individual patient's needs and the severity of their condition.
- It is essential to note that the provided evidence does not directly address the treatment of ENL, and the recommended treatment approach is based on general medical knowledge and guidelines for managing type 2 leprae reactions.

From the Research
Treatment Options for Erythema Nodosum Leprosum (ENL)
The treatment of ENL typically involves the use of various medications to control inflammation and prevent further episodes. Some of the commonly used treatments include:
- Corticosteroids, which are the anti-inflammatory of choice in ENL, but may cause dependence, especially in chronic patients 2
- Thalidomide, which has a rapid action but its use is limited due to teratogenicity and neurotoxicity 3, 4, 2
- Clofazimine, which has a slow action and may have important adverse effects 3, 2
- Cyclophosphamide pulse therapy, which may be useful and safe to control chronic recalcitrant ENL 5
- Etanercept, a tumor necrosis factor inhibitor, which has been used to treat severe refractory ENL 6
- Pentoxifylline, which has a slow action and may have important adverse effects 2
Drug of Choice for ENL
The drug of choice for ENL is often a matter of debate, as different patients may respond better to different treatments. However, based on the available evidence, corticosteroids and thalidomide are the mainstays of treatment for ENL 3, 4. Thalidomide has been shown to be effective in controlling ENL reactions and preventing recurrences, especially when used early in the treatment course 4. However, its use is limited due to its potential side effects, and corticosteroids may be preferred in some cases.
Challenges in ENL Treatment
The treatment of ENL is often challenging due to the lack of effective and safe treatment options. Many patients may not respond well to conventional treatments, and some may experience severe side effects 3, 2. Additionally, there is no standardized treatment protocol for ENL, making it difficult to evaluate and control the condition 2. Further research is needed to develop more effective and safe treatment options for ENL.
