Pain Management with Ibuprofen and Paracetamol

Initial Treatment Algorithm

The American College of Rheumatology recommends starting with paracetamol 1000mg every 6 hours (maximum 4g/24 hours) as first-line therapy for pain management, due to its superior safety profile, particularly regarding gastrointestinal, cardiovascular, and renal complications 1, 2
For most patients with mild to moderate pain, the European League Against Rheumatism (EULAR) suggests starting with paracetamol up to 4g daily as first-line therapy; if inadequate, substitute ibuprofen 1200mg daily, or add ibuprofen to paracetamol for enhanced pain relief 1, 2

Ibuprofen demonstrates superior analgesic efficacy compared to paracetamol across most pain conditions, according to the American College of Rheumatology, particularly in acute pain and osteoarthritis 2, 5
In patients with osteoarthritis, ibuprofen shows superior efficacy, as recommended by the American College of Rheumatology 5

The American Heart Association notes that paracetamol has minimal gastrointestinal toxicity at recommended doses (≤4g/24 hours) 2
The American College of Cardiology states that NSAIDs, including ibuprofen, increase the risk of myocardial infarction, stroke, and cardiovascular death, which may occur early in treatment, and that paracetamol does not carry these cardiovascular risks 2
The National Kidney Foundation indicates that NSAIDs cause dose-dependent renal toxicity, particularly in vulnerable patients, while paracetamol can be used safely in patients with renal impairment at standard doses 2

The American Geriatrics Society recommends choosing paracetamol (avoiding ibuprofen) if the patient has chronic kidney disease or creatinine clearance <60 mL/min, history of peptic ulcer disease or gastrointestinal bleeding, or is over 60 years with ≥2 additional risk factors 1, 2
The American College of Rheumatology suggests choosing ibuprofen if the patient has no contraindications listed above and requires superior analgesic efficacy, or has inflammatory pain conditions where anti-inflammatory effect is beneficial 1

The American Gastroenterological Association recommends adding a proton pump inhibitor if the patient has ≥2 risk factors: age >60, prior ulcer, concurrent aspirin, high-dose NSAID (≥2400mg/day ibuprofen) 1, 3

The American Medical Association advises against starting with ibuprofen before trying paracetamol alone, as this contradicts evidence-based guidelines prioritizing safety 1, 2
The American College of Rheumatology warns against exceeding paracetamol 4g/24 hours, as hepatotoxicity risk increases above this dose, and against exceeding ibuprofen 2400mg/24 hours, as adverse event rates increase significantly 1, 2, 3

The American College of Rheumatology recommends using both medications at the lowest effective dose for the shortest duration necessary, and reassessing the need for continued therapy after 1-2 weeks 5
