Eperisone for Myofascial Pain Syndrome
Eperisone is not recommended for myofascial pain syndrome, as it lacks evidence-based support in current clinical guidelines and has no established role in the treatment algorithm for this condition.
Why Eperisone Is Not Recommended
The available evidence does not support eperisone use for myofascial pain syndrome. Current high-quality guidelines from the American Urological Association, National Comprehensive Cancer Network, and European League Against Rheumatism do not include eperisone in their treatment recommendations 1, 2, 3. Recent systematic reviews examining pharmacologic interventions for myofascial pain syndrome found that muscle relaxants show insufficient or inconclusive evidence for effectiveness 4.
Evidence-Based First-Line Treatment Instead
Manual physical therapy techniques should be your initial treatment approach, as they provide the largest reduction in pain severity with minimal risk of harm 1, 3. The American Urological Association specifically recommends manual therapy including trigger point resolution, muscle lengthening techniques, and fascial restriction release as first-line treatment 1.
Treatment protocols should include:
- 10 sessions of 60 minutes over 12 weeks, which results in 59% of patients reporting moderate or marked improvement 3
- Progressive strengthening targeting affected muscle groups 2
- Postural retraining and correction 2
Pharmacologic Options With Evidence Support
If pharmacologic intervention is needed, consider these evidence-based alternatives:
Topical Agents (Preferred for Safety)
- Lidocaine patches 5% applied daily to painful sites with minimal systemic absorption 5, 1, 3
- Diclofenac patches (180 mg once or twice daily) or gel (applied 3 times daily) 5, 1, 2
Oral NSAIDs
For Persistent Pain
- Tricyclic antidepressants (nortriptyline 10-25 mg nightly, increase to 50-150 mg) or SNRIs (duloxetine 30-60 mg daily, increase to 60-120 mg) 5, 1, 2
- Anticonvulsants (gabapentin 100-300 mg nightly, titrate to 900-3600 mg daily in divided doses; or pregabalin 50 mg three times daily, increase to 100 mg three times daily) 5, 1
Critical Contraindications and Pitfalls
Avoid these common mistakes:
- Strong opioids should not be used for myofascial pain management 5, 1
- Corticosteroids have no role in isolated myofascial pain syndrome unless concomitant joint pathology exists 5, 1
- Paracetamol should not be used as monotherapy as it provides insufficient analgesia when used alone 1
- Muscle relaxants lack sufficient evidence and should not be routinely prescribed 4
Multimodal Approach Required
A multimodal approach combining non-pharmacologic and pharmacologic modalities is required; monotherapy strategies should be avoided to achieve optimal pain relief and functional improvement 1. This means combining manual therapy with appropriate pharmacologic agents and adjunctive therapies rather than relying on any single intervention.
Adjunctive Therapies
- Cognitive behavioral therapy can provide benefit, particularly when psychosocial factors contribute to pain chronicity 5, 1, 3
- Relaxation techniques and breathing exercises are useful additions 5
When Conservative Treatment Fails
Trigger point injections should only be considered as part of multimodal treatment after 3+ months of failed conservative treatment, not as standalone therapy 2, 3. Patients must continue concurrent physical therapy 3. Limit injections to 4 sets maximum to assess therapeutic response 2.
Botulinum toxin (onabotulinumtoxinA) may be employed as adjunctive treatment when other therapies have failed, though it is not recommended for routine use 1, 2.
