Paracetamol (acetaminophen) is among the most widely used analgesics worldwide. But does it live up to its reputation as a safe and effective painkiller? This 2021 overview consolidates findings from 10 Cochrane systematic reviews, covering over 20,000 participants, to reassess the efficacy and safety of paracetamol across a range of acute and chronic pain conditions.
🔍 Key Findings
✅ Where It Works
- Acute pain (e.g., postoperative pain, tension headaches):
Moderate evidence supports paracetamol’s efficacy.- In post-surgical pain: ~50% achieved ≥50% pain relief with a single 1,000 mg dose.
- In tension-type headaches: Slight benefit over placebo, but less than NSAIDs.
❌ Where It Doesn’t Work Well
- Chronic pain conditions:
- Low back pain: No significant benefit over placebo.
- Hip/knee osteoarthritis: Only very modest pain relief, not clinically meaningful.
- Cancer pain: Limited data; paracetamol is often used as adjunctive, not primary therapy.
⚠️ Safety Concerns
- Generally safe at therapeutic doses, with a strong safety record over decades.
- However, risk of liver toxicity increases sharply with overdose or long-term misuse.
- Widespread OTC availability may lead to public overconfidence in its safety profile.
- Concerns also noted around combination products with opioids, which may obscure toxicity risk.
🧠 Clinical Implications
- For acute, self-limiting pain, paracetamol remains a reasonable first-line choice.
- For chronic musculoskeletal conditions, clinicians should reconsider its use—particularly as a standalone therapy.
- Emphasizes the importance of shared decision-making, especially for long-term users with limited benefit.
