Treatment of Pericarditis with Friction Rub
Treat with combination therapy of high-dose NSAIDs (aspirin 750-1000 mg every 8 hours OR ibuprofen 600 mg every 8 hours) PLUS colchicine (0.5 mg once daily if <70 kg or twice daily if ≥70 kg) for 1-2 weeks with gastroprotection, followed by gradual tapering guided by symptom resolution and CRP normalization. 1
First-Line Treatment Regimen
The presence of a pericardial friction rub confirms the diagnosis of acute pericarditis and mandates immediate anti-inflammatory therapy. The 2015 ESC Guidelines provide Class I, Level A recommendations for this dual-drug approach 1:
NSAIDs (Choose One):
- Aspirin: 750-1000 mg every 8 hours
- Ibuprofen: 600 mg every 8 hours
- Always provide gastroprotection (proton pump inhibitor)
Colchicine (Mandatory Addition):
- <70 kg: 0.5 mg once daily
- ≥70 kg: 0.5 mg twice daily
- Duration: 3 months minimum
- Purpose: Reduces recurrence risk from 37.5% to 16.7% 2
Treatment Duration and Tapering
Continue full-dose NSAIDs for 1-2 weeks or until:
- Complete symptom resolution
- CRP normalization
- Then taper NSAIDs by 250-500 mg (aspirin) or 200-400 mg (ibuprofen) every 1-2 weeks 1
Critical pitfall: Inadequate initial treatment duration is a common cause of recurrence. Do not rush tapering if symptoms persist or CRP remains elevated 1.
Risk Stratification Determines Setting
Low-risk patients (no high-risk features) can be managed outpatient with close follow-up 1:
- Fever >38°C
- Subacute onset
- Large pericardial effusion (>20 mm)
- Cardiac tamponade
- Immunosuppression
- Trauma
- Oral anticoagulation
- Myopericarditis (elevated troponin)
- Failure to respond to NSAIDs after 7 days
If ANY high-risk feature is present, admit for etiology workup and monitoring 1.
When NOT to Use Corticosteroids
Corticosteroids are NOT recommended as first-line therapy (Class III recommendation) 1. They increase recurrence rates and promote chronicity. Reserve corticosteroids only for:
- True contraindication to NSAIDs (not just preference)
- Failure of NSAIDs + colchicine combination
- Specific indications: autoimmune disease, uremia, pregnancy
- If used: low-dose only (prednisone 0.2-0.5 mg/kg/day), never high-dose 1
Activity Restriction
Non-athletes: Restrict exercise until symptom resolution, CRP normalization, and normal ECG/echo 1
Athletes: Minimum 3-month restriction from competitive sports after symptom onset, even if earlier resolution occurs 1
Monitoring Response
Use CRP levels to guide treatment duration and assess response 1. Continue therapy until CRP normalizes, as persistent elevation predicts recurrence even if symptoms improve.
If Treatment Fails
If no response after 7 days of appropriate NSAID + colchicine therapy:
- Admit patient for etiology search 1
- Rule out specific causes (tuberculosis, malignancy, autoimmune disease)
- Consider low-dose corticosteroids as add-on (not replacement) therapy
- For multiple recurrences: IL-1 blockers (rilonacept, anakinra) may be superior to corticosteroids 2, 3
The friction rub itself requires no specific intervention—it is a diagnostic finding that confirms pericardial inflammation and will resolve with appropriate anti-inflammatory treatment.
