An oral suspension of activated charcoal (AC) should be considered in poisonings when gastrointestinal decontamination of a xenobiotic is indicated, and AC can be administered within 1 hour of ingestion. Careful consideration of the contraindications (click here) should occur prior to treatment with activated charcoal.  

The recommended target dose of AC was 1 g/kg of bodyweight, but at least tenfold the estimated weight of the suspected toxin, the maximum being 50 g.  

Single dose activated charcoal for gut decontamination:

After ingestion of a potentially toxic substance, Single Dose Activated Charcoal (AC) is the most applied decontamination procedure . It is easy to use, inexpensive and safe . With increasing lag-time between toxin-ingestion and AC-application the efficacy of AC to decontaminate declines rapidly . Thus, AC should be applied as soon as possible. Pre- and extra-hospital AC-application may shorten this lag time . This implies AC application by non-medical persons (=laypersons). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5615092/


It is also good to remove toxins from kidney patients




Activated charcoal seemed to have the best risk:benefit ratio among gastric lavage, ipecacuanha, or supportive treatment if given within four hours of ingestion (Paracetamol over dose).
