What is the primary indication for administering activated charcoal?

• A. Reduction of fever
• B. Hypertension management
• C. Poisoning and overdose
• D. Infection control

Answer: (C)

Activated charcoal works by binding many toxins in the gastrointestinal tract, which helps prevent or reduce their absorption into the bloodstream. The primary reason to administer it is suspected poisoning or overdose, especially when the toxin is one that charcoal can adsorb and the patient can protect their airway. It’s most effective if given soon after ingestion, typically within the first hour. It’s not used to lower fever, manage high blood pressure, or prevent infection—those conditions are treated with other therapies. It also isn’t appropriate if the patient cannot protect their airway or if the ingestion involved caustic substances or hydrocarbons, since charcoal can cause aspiration or worsen injury in those cases.
