Management of Lumbar Radiculopathy

Evidence Against Systemic Corticosteroids

Oral corticosteroids, including Medrol dose packs, are not recommended for lumbar radiculopathy as they provide no meaningful benefit over placebo and cause significant adverse effects including insomnia, nervousness, and increased appetite 1
Six trials consistently found no differences between systemic corticosteroids and placebo for pain relief in radicular low back pain of varying duration 1
Systemic corticosteroids do not reduce the likelihood of requiring spine surgery 1
For spinal stenosis specifically, a 3-week course of prednisone showed no differences from placebo in pain intensity or disability through 12 weeks of follow-up 1
Oral prednisone significantly increases risk of any adverse event (49% vs 24%) compared to placebo 1
Specific harms include insomnia (26% vs 10%), nervousness (18% vs 8%), and increased appetite (22% vs 10%) 1

NSAIDs (such as naproxen) are recommended as first-line treatment for radiculopathy due to moderate efficacy and better safety profile 2
NSAIDs target the inflammatory component of radicular pain 2
Use the lowest effective dose to minimize gastrointestinal and cardiovascular risks 2
Gabapentin shows small to moderate short-term benefits for radicular pain, particularly effective for the neuropathic component 2
Doses of gabapentin are typically titrated to 1200-3600 mg/day 2
The American College of Physicians recommends starting with NSAIDs to address inflammatory component, then adding gabapentin if neuropathic pain persists 2

Start with NSAIDs to address inflammatory component 2
Add gabapentin if neuropathic pain persists 2
Consider epidural steroid injections (not oral steroids) for persistent symptoms in surgical candidates 3
Advise patients to remain active and provide self-care education 3, 4

Do not prescribe oral corticosteroids (Medrol dose packs) for routine lumbar radiculopathy - the evidence shows no benefit with significant harms 1
Avoid long-term use of any glucocorticoids for this indication 5
Most patients with lumbar disc herniation and radiculopathy improve within the first 4 weeks with noninvasive management 3
