What are some complications and contraindications to activated
charcoal?
Complications: Aspiration, admin into lungs, emesis, constipation GI

Contraindications: Unconscious state/ inability to maintain airway, recent
GI surgery.
,Is multi-dose activated charcoal better than single dose regimens?

, When is the best time to use Whole Bowel Irrigation?
(not recommended for routine use) but...

1. Ingestion of Medications with long half-life, sustained release, or
enteric coated formulations.
