Ibuprofen is preferred over paracetamol for fever and throat pain

For an adult with fever and sore throat, ibuprofen is the better choice as it provides superior pain relief compared to paracetamol, while both drugs are equally safe and effective for fever reduction. 1

Evidence-Based Reasoning

Pain Relief Superiority

The European guideline on acute sore throat management clearly states that ibuprofen and diclofenac are slightly more effective than paracetamol for pain relief 1. This is supported by systematic reviews and multiple randomized controlled trials demonstrating that NSAIDs provide better analgesia for throat pain than paracetamol 1.

A direct comparison study found that 400 mg ibuprofen was significantly more effective than 1000 mg paracetamol for pain intensity on swallowing, difficulty swallowing, and global pain relief at all time points measured over 6 hours 2. This is particularly relevant since you're using a lower dose of ibuprofen to achieve better results than a higher dose of paracetamol.

Fever Control

For fever reduction, both medications are equally effective:

  • Recent emergency department studies show both IV ibuprofen 400 mg and IV paracetamol 1000 mg provide equivalent fever control within 30-60 minutes 3
  • Meta-analysis confirms equal antipyretic efficacy in both adult and pediatric populations 4

Safety Profile

Both medications are equally safe for short-term use 1. The guideline specifically notes that "paracetamol and ibuprofen were the safest" options, and a large RCT confirmed that ibuprofen, when used according to usual contraindications, was as well tolerated as paracetamol for treating cold, flu, and sore throat symptoms 1.

Practical Dosing

Ibuprofen: 400 mg every 4-6 hours as needed (maximum 3200 mg/day, though doses above 2400 mg rarely provide additional benefit) 5

Paracetamol (if ibuprofen contraindicated): 1000 mg every 6 hours (maximum 4000 mg/day) 6

Important Caveats

  • Avoid ibuprofen if: active peptic ulcer disease, severe renal impairment, heart failure, or aspirin-sensitive asthma 5
  • Avoid paracetamol if: severe liver disease or chronic alcohol use (≥3 drinks daily) 6
  • Most sore throats are viral and self-limiting (resolving within 7 days) - antibiotics are not indicated unless streptococcal infection is confirmed 7
  • Patients should be educated that effective pain control requires regular dosing rather than as-needed use, as many patients underutilize analgesics before seeking medical care 8

The clinical bottom line: Start with ibuprofen 400 mg every 4-6 hours for superior throat pain relief and equivalent fever control, switching to paracetamol only if contraindications exist.
