What precautions apply to Orphenadrine Citrate, Paracetamol?
Before prescribing Norgesic, clinicians should consider several precautionary measures to ensure safe use.
Assess hepatic function: avoid use in patients with severe liver impairment. Monitor for anticholinergic effects: caution in elderly or those with glaucoma.

What does Orphenadrine Citrate, Paracetamol interact with?
Norgesic can interact with other medicines, altering its efficacy or safety profile.
Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis. - Other anticholinergic agents: additive anticholinergic burden. - CYP450 inhibitors (e.g., ketoconazole): may increase paracetamol levels. - Alcohol: enhances CNS depression and hepatotoxic risk. - Warfarin: paracetamol may potentiate anticoagulant effect.
Moderate Interactions (Monitor Closely): - CNS depressants (benzodiazepines, opioids): increased sedation. - Other analgesics containing paracetamol: risk of overdose. - Antihistamines: may increase anticholinergic side effects. - Beta‑blockers: may mask tachycardia from anticholinergic effect. - Lithium: potential for increased lithium levels.
