What is the dose of activated charcoal for adults and children?

• A. 1 g/kg PO
• B. 10 g PO
• C. 0.1 g/kg IV
• D. 50 g IV

Answer: (B)

Activated charcoal works by adsorbing many drugs and toxins in the stomach and intestines, preventing their absorption into the bloodstream. In typical EMS practice, a single oral dose of 10 grams is given to both adults and children, making it a simple, standardized treatment in the field. It should be administered with water to create a slurry and is most effective when given soon after ingestion, ideally within the first hour.

Keep in mind it’s not appropriate for every ingestion. Do not use it when the patient cannot protect their airway or if the substance ingested is a caustic (acid or alkali) or a hydrocarbon, or if there are other contraindications such as a risk of aspiration or a bowel obstruction.
