In cases of poisoning, what is the primary consideration when administering activated charcoal?

The primary consideration when administering activated charcoal in cases of poisoning is if the known poison was ingested less than one hour ago. Activated charcoal acts by adsorbing the poison in the gastrointestinal tract, thus reducing its absorption into the bloodstream. This is most effective when administered soon after ingestion, typically within the first hour.

Administering activated charcoal too late, such as after one hour, may not provide the intended benefit as the poison may have already been absorbed. Therefore, timing is crucial in determining the appropriateness of activated charcoal treatment. The other situations, such as a patient being unconscious or displaying seizures, do not directly address the urgency and timing concerning the effectiveness of activated charcoal administration in relation to the ingestion of the poison.
