What precautions apply to Orphenadrine Citrate, Paracetamol?
Before prescribing Norgesic, clinicians should consider several safety measures.
- Assess liver function: monitor patients with existing hepatic disease. - Avoid alcohol: concurrent use increases risk of liver injury. - Use caution in elderly: heightened sensitivity to sedation and anticholinergic effects. - Review concomitant CNS depressants: may enhance drowsiness. - Pregnancy: consult a healthcare professional as safety has not been established. - Store at ambient temperature: keep in the original pack, protect from moisture and heat.
What does Orphenadrine Citrate, Paracetamol interact with?
Norgesic can interact with other medicines, requiring careful management.
Major Interactions (Avoid): - Hepatotoxic drugs (e.g., high‑dose ibuprofen, certain antituberculars): increased risk of liver damage. - Other anticholinergic agents (e.g., diphenhydramine): additive anticholinergic burden. - Strong CYP450 inhibitors (e.g., ketoconazole): may raise paracetamol plasma levels.
Moderate Interactions (Monitor Closely): - Alcohol: can potentiate sedation and hepatic stress. - CNS depressants (opioids, benzodiazepines): enhanced drowsiness and impaired coordination. - Warfarin: paracetamol may modestly increase anticoagulant effect, requiring INR monitoring.
