From the Guidelines
Paracetamol is recommended as a first-line agent for the treatment of musculoskeletal pain due to its favorable safety profile compared to NSAIDs, with a recommended dosing of 4 g/day, although lower dosing is recommended for patients with liver disease 1.
Key Points to Consider
- Paracetamol has minimal anti-inflammatory effects and doesn't irritate the stomach lining, making it suitable for people who cannot tolerate NSAIDs.
- The standard adult dose is 500-1000mg every 4-6 hours, not exceeding 4000mg in 24 hours.
- For children, dosing is weight-based, typically 10-15mg per kilogram of body weight every 4-6 hours.
- Paracetamol must be used cautiously as overdose can cause severe liver damage.
- Those with liver disease should consult a healthcare provider before use and alcohol should be avoided when taking paracetamol as this increases the risk of liver toxicity.
Safety Profile
- Recent studies have raised concerns about the possible GI toxicity of paracetamol, but evidence from a systematic review of RCTs shows that paracetamol has no more GI upsets than placebo (RR = 0.80,95% CI 0.27 to 2.37) 1.
- A meta-analysis of case-control studies also showed no increased risk of GI bleeding with paracetamol 2–4 g daily (OR = 1.2,95% CI 0.8 to 1.7) 1.
- However, a systematic literature review of observational studies found a consistent dose–response relationship between paracetamol at standard analgesic doses and adverse events, including mortality, cardiovascular, GI, and renal events 1.
Clinical Considerations
- Clinicians should be aware of the potential risks associated with paracetamol use and monitor patients closely, especially those with pre-existing medical conditions.
- Patients should be educated on the safe use of paracetamol, including the importance of not exceeding the recommended dose and avoiding concomitant use of other medications that may increase the risk of adverse events.
- Alternative treatment options, such as NSAIDs or opioids, may be considered for patients who are at high risk of adverse events or who have not responded to paracetamol therapy.
