Study notes
A paracetamol overdose patient arrives at 6 hours — N-acetylcysteine is started. Paracetamol poisoning kills the liver silently — N-acetylcysteine (NAC) replenishes glutathione, preventing hepatic necrosis; the Rumack-Matthew nomogram (level vs time) decides treatment. Give within 8 hours for best effect — but treat late presenters too. Activated charcoal only helps within 1 hour. The overdose that feels fine at hour 2 destroys at day 3 — time-based toxicology.
