Activated charcoal is a gastrointestinal adsorbent used in the management of acute oral poisoning and overdose. Activated charcoal binds to several drugs and toxins in the gastrointestinal tract, thereby reducing systemic absorption and limiting toxicity. Activated charcoal is most effective when administered soon after ingestion, although later administration may be beneficial in selected cases involving delayed absorption. This activity reviews the pharmacology, indications, contraindications, administration, adverse effects, drug interactions, and monitoring parameters associated with activated charcoal. Particular attention is given to patient selection, timing of administration, dosage, formulation type, airway protection, aspiration risk, and other safety considerations. This activity also highlights the importance of interprofessional collaboration among healthcare professionals to ensure the safe administration of activated charcoal and to optimize clinical outcomes in patients with poisoning. Objectives: Identify the indications for activated charcoal use in patients with acute oral poisoning or overdose. Screen patients for contraindications to activated charcoal administration, including impaired airway reflexes, aspiration risk, bowel obstruction, and gastrointestinal perforation. Select the appropriate activated charcoal formulation, dose, and route of administration based on patient factors and the ingested toxin. Collaborate with interprofessional healthcare providers to monitor treatment response, adverse effects, and the need for additional interventions after activated charcoal administration.

No significant toxicity from activated charcoal is expected as it is not absorbed systemically; however, adverse effects from its administration, such as emesis, aspiration, and bowel obstruction, may occur.

Activated charcoal is commonly used in emergency departments for the treatment of toxic ingestions. When administered soon after ingestion, it can significantly reduce the absorption of many drugs and toxins. However, evidence demonstrating improvement in patient-oriented outcomes remains limited, and activated charcoal administration carries potential risks, including aspiration and gastrointestinal complications. Healthcare professionals in the emergency department, including nurses, pharmacists, and physicians, should understand the appropriate indications, timing, dosing, and risks associated with the use of activated charcoal. Because activated charcoal is also marketed in health food stores for various unregulated purposes, patients should be educated about the potential risks associated with its unregulated use.[4][21] Clinicians considering the use of activated charcoal should consult a clinical pharmacist, toxicologist, or Poison Control Center when there is uncertainty regarding its appropriateness. These resources can also provide guidance on dosing and administration. Nurses are responsible for administering activated charcoal, monitoring for adverse effects, and assessing the effectiveness of the intervention. Clear communication among healthcare team members and documentation of interventions and patient responses are essential. An effective interprofessional approach can help optimize outcomes in patients with toxic ingestions.
