Treatment Recommendations for Costochondritis
First-line treatment for costochondritis is NSAIDs at maximum tolerated and approved dosage, with treatment response evaluated after 2-4 weeks. 1
Pharmacological Management
NSAIDs as Primary Therapy
- Start with oral NSAIDs at the lowest effective dose for the shortest possible period to minimize systemic risks, particularly gastrointestinal, hepatic, and cardiorenal toxicity 1
- Consider topical NSAIDs to reduce systemic side effects while maintaining local anti-inflammatory action 1
- For patients with increased gastrointestinal risk (elderly, history of peptic ulcer disease, concurrent corticosteroid use), use either:
- Non-selective NSAIDs plus a gastroprotective agent (proton pump inhibitor or H2-blocker), OR
- Selective COX-2 inhibitor 1
- The risk reduction with COX-2 inhibitors versus non-selective NSAIDs is substantial (RR 0.18,95% CI: 0.14-0.23) 1
Alternative and Adjunctive Analgesics
- Use acetaminophen (paracetamol) at regular dosing intervals when NSAIDs are insufficient, contraindicated, or poorly tolerated 1
- Acetaminophen can be added to NSAIDs if response is inadequate after 2-4 weeks 1
Corticosteroid Options
- Local corticosteroid injections directed to the specific costochondral junction may be considered for persistent focal pain despite adequate NSAID therapy 1, 2
- Short courses of oral prednisolone may serve as bridging therapy while awaiting effect of other agents 1
- Avoid long-term systemic corticosteroids due to lack of evidence for axial/chest wall pain and significant adverse effect profile 1, 2
Non-Pharmacological Interventions
Physical Modalities
- Apply local heat or cold applications to the affected costochondral area 1
- Stretching exercises targeting the pectoralis muscles and chest wall demonstrate progressive significant improvement (p<0.001) compared to standard care alone 3
- Regular exercise and physical therapy should be incorporated into the treatment plan 1
Patient Education
- Provide education about the benign, self-limiting nature of costochondritis 1
- Advise temporary avoidance of activities producing chest muscle overuse or repetitive movements 4
Treatment Algorithm
Initial approach (Weeks 0-4):
- Start NSAID therapy at appropriate dose based on GI/cardiovascular risk profile 1
- Add local heat/cold applications 1
- Initiate stretching exercises 3
- Provide reassurance about benign nature 4
If inadequate response after 2-4 weeks:
- Switch to different NSAID, OR 1
- Add acetaminophen to existing NSAID regimen 1
- Consider local corticosteroid injection for focal persistent tenderness 1
For refractory cases:
- Refer for physical therapy with manual manipulation techniques and instrument-assisted soft tissue mobilization 5
- Re-evaluate diagnosis to exclude infectious costochondritis or other serious pathology 6
Critical Safety Considerations
Monitoring Requirements
- Monitor for gastrointestinal, hepatic, and cardiorenal toxicity with prolonged NSAID use, particularly in elderly patients and those with comorbidities 1
- The risk of serious GI complications with NSAIDs is significant (RR 5.36,95% CI: 1.79-16.10) 1
Red Flags Requiring Further Evaluation
- Patients older than 35 years or those with coronary artery disease risk factors require electrocardiogram and possibly chest radiograph before diagnosing costochondritis 4
- Presence of fever, purulent drainage, or systemic symptoms suggests infectious costochondritis requiring antibiotics and possible surgical debridement 6
- Cardiopulmonary symptoms warrant cardiac workup, as coronary artery disease is present in 3-6% of adult patients with chest pain and chest wall tenderness 4
Common Pitfalls to Avoid
- Do not assume all anterior chest wall pain is benign costochondritis without appropriate cardiac risk stratification in adults over 35 years 4
- Avoid long-term systemic corticosteroid therapy, which lacks evidence and carries significant adverse effects 1, 2
- Do not overlook infectious costochondritis in patients with diabetes, recent surgery, or immunocompromise 6
- NSAIDs alone may have insufficient effectiveness; combining with stretching exercises improves outcomes 3
