Activated Charcoal (cont.)
How Activated Charcoal Is Given
Activated charcoal may be given by mouth to someone who is awake and alert. It is a black liquid drink.
- If the person vomits the drink, another dose will be given through a
nasogastric or orogastric tube (a tube inserted through the nose or mouth,
down the esophagus and into the stomach).
- If the person is unconscious (or nearly so), an endotracheal intubation (a procedure in which a tube is inserted through the mouth down into the trachea) may be necessary. This allows
oxygen to be delivered and helps protect the airway and lungs from gastric content,
which minimizes the risk of the person
vomiting and choking.
- Activated charcoal is usually given by a doctor. It is not a substance to be used at home. Doctors determine the dose or amount of charcoal to give based on the
patient's weight (with special doses for children) and on how much poison was swallowed. There are some doctors who will prescribe charcoal for emergency use in the home. This should only be done under the direct guidance of the doctor or poison control center.
In the United States, the direct line to the poison control center is
- The doctor also determines when and if additional doses are given by monitoring blood levels of the poison. Other symptoms the doctor monitors are
nausea and vomiting,
abdominal pain, dizziness, and severe heart problems. Multiple doses of activated charcoal can be given if someone swallowed large doses of long-acting, sustained release medications.
- In some cases, if blood levels of the poison remain too high, the doctor may recommend kidney dialysis.
Dialysis may be the best way to remove the toxin from the bloodstream.
