What do emts do for drug overdose?

It depends on the type of overdose and the current health of the patient. If a patient is unconscious, a Paramedic is required to intervene by injecting certain medications intravenously. If this is unavailable, then the patient must be rapidly transported to a hospital for greater medical care. If a patient is conscious and cooperative, an EMT-Basic might have the patient drink Activated Charcoal. Charcoal can bond with certain poisons, allowing them to pass through the patient's digestive system without being absorbed.
No matter the case, EMTs must often rely on the more specific knowledge of the Poison Control Center before intervening.
