What is the typical route and timing for activated charcoal administration?

Explanation:
Activated charcoal works by binding ingested toxins in the gastrointestinal tract to prevent their absorption. The most effective approach is to give it by mouth (or via a tube if the patient cannot swallow) within about one hour of ingestion, and only if the patient can protect their airway or has an airway that is secured. This early timing matters because the charcoal’s adsorption of many substances is strongest soon after ingestion; as time passes, the benefit diminishes. Intravenous administration wouldn’t adsorb toxins in the gut, and sublingual or inhaled routes don’t bring the charcoal into contact with the ingested material, so they’re not appropriate. It’s also essential that the patient isn’t at risk of aspiration, hence the emphasis on airway protection.
