What is the recommended dosage and treatment duration for a steroid (corticosteroid) pack, such as prednisone, for acute back pain?

Steroid Packs for Back Pain: Not Recommended for Acute Low Back Pain

Systemic corticosteroids (steroid packs) are not recommended for acute low back pain as they show no benefit over placebo for pain relief or function improvement.1, 2

Evidence Against Systemic Corticosteroids for Back Pain

• Low-quality evidence from clinical trials shows no difference in pain or function between:

  • A single intramuscular injection of methylprednisolone or
  • A 5-day course of prednisolone compared with placebo in patients with acute low back pain 1

• A randomized controlled trial found no benefit from a 5-day course of 50mg daily prednisone compared to placebo for musculoskeletal low back pain 3

• The American College of Physicians specifically recommends against routine use of steroid packs for back pain due to:

  • Minimal evidence of benefit
  • Significant risk of adverse effects 2

Appropriate First-Line Treatments for Acute Low Back Pain

Instead of corticosteroids, consider these evidence-based options:

1. NSAIDs: Moderate-quality evidence shows NSAIDs provide small improvement in pain intensity compared with placebo 1

2. Skeletal Muscle Relaxants (SMRs): Moderate-quality evidence shows SMRs improve short-term pain relief compared with placebo after 2-7 days 1

3. Non-pharmacological approaches: Should be prioritized, including physical therapy 2

Limited Role for Systemic Corticosteroids

If considering corticosteroids despite the evidence against their routine use:

• Reserve for: Severe, acute radicular pain (not non-radicular back pain) that has not responded to other treatments 2

• Dosing: If used, limit to no more than 1-2 short courses per year 2

  • Typical course: Prednisone 50mg daily for 5 days (though evidence shows this is ineffective) 3
  • Keep cumulative annual dose below 5g to avoid very high fracture risk 2

Adverse Effects of Systemic Corticosteroids

Even short courses carry significant risks:

• Increased risk of any adverse event (49% vs. 24% with placebo) 2
• Common side effects:
  • Insomnia (26% vs. 10%)
  • Nervousness (18% vs. 8%)
  • Increased appetite (22% vs. 10%) 2
• Long-term risks with repeated courses:
  • Glucocorticoid-induced osteoporosis
  • Increased fracture risk, especially with cumulative doses ≥5g over 1 year 2

Monitoring and Mitigation Strategies

If corticosteroids are used despite recommendations against them:

• Assess for adverse effects from previous courses
• Consider calcium (1000-1200 mg) and vitamin D (600-800 IU) supplementation during treatment 2
• Evaluate bone health if multiple courses are needed 2

Bottom Line

For acute low back pain, the evidence clearly shows that systemic corticosteroids provide no benefit over placebo while introducing significant risks. NSAIDs and skeletal muscle relaxants are more appropriate pharmacological options, alongside non-pharmacological approaches like physical therapy.
