Baclofen for Back Pain: Efficacy and Safety

Introduction to Baclofen Use

The American College of Physicians does not recommend baclofen as a preferred option for muscle relaxant therapy in low back pain 4
Tizanidine is considered a more effective muscle relaxant option for lumbar radiculopathy with a better safety profile than baclofen 4

NSAIDs have good evidence for effectiveness in both acute and chronic low back pain with moderate pain relief 2, 3
Skeletal muscle relaxants like tizanidine are effective for short-term pain relief in acute low back pain 2, 3
For chronic low back pain, tricyclic antidepressants show small to moderate effects for pain relief 2, 5
Gabapentin has demonstrated small, short-term benefits specifically in patients with radiculopathy 1, 4

For acute low back pain, the American College of Physicians recommends NSAIDs as first-line pharmacological treatment 2, 3
If additional pain relief is needed, consider tizanidine rather than baclofen 4
For chronic low back pain, NSAIDs or tricyclic antidepressants are recommended as first-line pharmacological options 2, 5
For low back pain with radiculopathy, consider gabapentin which has demonstrated benefits specifically for radicular symptoms 1, 4

Time-limited courses of therapy are recommended for all muscle relaxants due to limited evidence on benefits and risks associated with long-term use 1, 2
Systemic corticosteroids are not recommended for treatment of low back pain with or without sciatica 1, 4
