Oral Steroids for Lumbar Radiculopathy

Evidence Against Oral Steroids

The American College of Physicians recommends against the use of oral steroids, including methylprednisolone, for treating lumbar radiculopathy, as multiple high-quality trials consistently demonstrate no benefit for pain relief or functional improvement, while significantly increasing adverse events 1, 2
Six trials consistently found no differences between systemic corticosteroids and placebo in pain relief for radicular low back pain of varying duration, according to the American College of Physicians 1, 2
The largest good-quality trial (n=269) showed only small functional effects, while two other trials found no functional benefits, as reported by the American College of Physicians 1, 2
Two trials found no effect on the likelihood of requiring spine surgery, as analyzed by the American College of Physicians 1, 2

Any adverse event occurred in 49% of patients vs 24% with placebo (P < 0.001) in the largest trial using oral prednisone 60 mg/day, according to the American College of Physicians 1, 2
Insomnia occurred in 26% of patients vs 10% (P = 0.003), nervousness in 18% vs 8% (P = 0.03), and increased appetite in 22% vs 10% (P = 0.02), as reported by the American College of Physicians 1, 2

The American College of Physicians recommends not prescribing oral corticosteroids as they provide no meaningful benefit over placebo for pain or function 1, 2

The evidence base for lumbar radiculopathy is distinct from that of other conditions, such as Crohn's disease, ulcerative colitis, and sudden hearing loss, where steroids have demonstrated efficacy, as noted by the American College of Physicians and other guideline societies 1, 2, 3, 4, 5, 6
Prolonged courses of oral steroids beyond 10-14 days dramatically increase complications without additional benefit, according to the American College of Physicians 1, 2
Patients with poorly controlled diabetes, labile hypertension, history of steroid-induced psychosis, or prior serious steroid complications should avoid systemic corticosteroids, as recommended by relevant guideline societies 6

The methylprednisolone dose pack provides only 84 mg total methylprednisolone, equivalent to just 105 mg prednisone over 6 days, which is grossly inadequate compared to the 540 mg prednisone over 14 days required for conditions where steroids are effective, according to the American Academy of Otolaryngology-Head and Neck Surgery 7
