What are the treatment options for arthralgia (joint pain)?

Treatment Options for Arthralgia

The mainstay of treatment for arthralgia should begin with simple analgesia such as paracetamol (acetaminophen) up to 4g daily, followed by NSAIDs like naproxen or ibuprofen if symptoms persist, with treatment tailored to the underlying cause of joint pain. 1

Initial Assessment and Classification

Arthralgia (joint pain) can be classified into several categories that guide treatment:

• Inflammatory arthralgia: Associated with morning stiffness, improvement with movement, and joint swelling
• Non-inflammatory arthralgia: Pain without significant inflammation
• Arthralgia related to specific conditions: Such as IBD-associated arthropathy or immune checkpoint inhibitor-related joint pain

First-Line Treatment

1. Simple Analgesia:

   • Paracetamol (acetaminophen) up to 4g daily 1
   • Safe first-line option with favorable side effect profile

2. Topical Treatments:

   • Topical NSAIDs (e.g., diclofenac gel) for accessible joints 1
   • Topical lidocaine 5% patches for localized pain 2

Second-Line Treatment

1. Oral NSAIDs:

   • Naproxen 500mg twice daily 1, 3
   • Ibuprofen 1.2-2.4g daily 1
   • Meloxicam 7.5-15mg daily 2

   Important cautions with NSAIDs 3:

   • Increased risk of cardiovascular events with longer use
   • Risk of GI bleeding and ulceration
   • Should be used at lowest effective dose for shortest duration
   • Consider gastroprotection in high-risk patients

2. Combination Therapy:

   • Paracetamol plus NSAIDs if monotherapy is ineffective 1

Treatment Based on Specific Conditions

For IBD-Associated Arthropathy

• Type 1 (peripheral) arthropathy (related to IBD activity):

  • Control of underlying gut inflammation is the mainstay of treatment 2
  • Simple analgesia and physiotherapy 2
  • Short-term systemic corticosteroids for flares 2
  • Local steroid injections for persistent symptoms 2

• Type 2 (peripheral) arthropathy (independent of gut activity):

  • NSAIDs (if IBD is in remission) 2
  • Sulfasalazine for persistent symptoms 2
  • Methotrexate for refractory cases 2
  • Rheumatology referral for persistent symptoms 2

For Immune Checkpoint Inhibitor-Related Arthralgia

Based on severity 2:

• Grade 1 (mild pain):

  • Continue immunotherapy
  • NSAIDs for 4-6 weeks
  • Consider prednisone 10-20mg daily if NSAIDs ineffective
  • Consider intra-articular corticosteroid injection if ≤2 joints affected

• Grade 2 (moderate pain limiting instrumental ADLs):

  • Consider holding immunotherapy
  • Rheumatology referral
  • Prednisone 20mg daily for 2-4 weeks, increase to 1mg/kg/day if no response

• Grade 3 (severe pain limiting self-care):

  • Hold immunotherapy
  • Rheumatology referral
  • Prednisone 1mg/kg/day
  • Consider additional immunosuppression (methotrexate, sulfasalazine, leflunomide) 2

Non-Pharmacological Interventions

1. Physical Activity and Exercise:

   • Individually tailored physical exercise or strength training 2
   • Referral to physiotherapist if needed

2. Education and Self-Management:

   • Information about condition and pain management strategies 2
   • Sleep hygiene interventions 2

3. Weight Management:

   • Particularly important for knee arthralgia 1

When to Consider Additional Treatments

1. Corticosteroids:

   • Low-dose prednisone (10-20mg daily) for inflammatory arthralgia not responding to NSAIDs 2
   • Short-term use (2-4 weeks) followed by tapering 2

2. Disease-Modifying Antirheumatic Drugs (DMARDs):

   • Sulfasalazine for persistent peripheral arthropathy 2
   • Methotrexate for refractory cases 4
   • Monitor for potential side effects including hepatotoxicity, bone marrow suppression 4

3. Biologic Therapy:

   • Anti-TNF therapy for refractory cases, particularly in IBD-associated arthropathy 2
   • Consider in patients with axial spondyloarthropathy not responding to NSAIDs 2

When to Refer to a Specialist

• Persistent symptoms despite 4-6 weeks of treatment 1
• Signs of inflammatory arthritis (swelling, morning stiffness) 1
• Significant functional impairment 1
• Systemic symptoms 1
• Suspected axial spondyloarthropathy 2

Special Considerations

• NSAIDs should be used cautiously in patients with IBD, only if disease is in remission 2
• Patients on immunotherapy may develop arthralgia as an immune-related adverse event, often responding to NSAIDs and low-dose corticosteroids 5
• Early diagnosis and treatment of inflammatory arthralgia is important to prevent progression to chronic arthritis 6, 7

Remember that arthralgia can significantly impact quality of life, particularly in women who are disproportionately affected by many arthralgia-causing conditions 8. Early appropriate treatment can prevent disability and improve outcomes.
