If someone may have swallowed something harmful, get expert help now. In the US, use the Poison Control online tool or call a poison center at 1-800-222-1222. [1] If the person collapses, has a seizure, has trouble breathing or cannot be awakened, call 911 now. [1] Poison Help is free, expert and confidential. [1] Poison Control's advice is not to guess what to do. [2] Do not give charcoal on your own. For other countries see Poison Help by country.
If you are thinking about harming yourself, call 988 (Suicide & Crisis Lifeline, US) as well as getting poison help.
Why charcoal is not a home step
- It is a hospital treatment. Poison Control says activated charcoal can adsorb many poisons in the gut and reduce how much enters the body. [2] But it works only for substances that stick to it, and timing matters: the sooner it is given the better it works. [2] Toxicology bodies add that the effectiveness decreases with time. [3]
- The decision is not routine, even for professionals. A 2005 joint position paper from the American Academy of Clinical Toxicology and the European Association of Poisons Centres and Clinical Toxicologists said single-dose activated charcoal should not be given routinely in the management of poisoned patients. [3] It also said there were no satisfactorily designed clinical studies of benefit and no evidence that it improves clinical outcome. [3]
- Airway safety. The same paper says that unless the patient has an intact or protected airway, giving charcoal is contraindicated. [3] Poison Control lists breathing the powder or slurry into the lungs among the risks, especially if the person is very drowsy. [2]
- Store products are not the same. Over-the-counter products might not be as "activated" as the charcoal used in an emergency room. [2] The usual tablet is 250 mg, and the emergency room amount (50 to 100 g) would take hundreds of tablets. [2]
- Not for everyone. It should not be taken by anyone with gastrointestinal bleeding, a bowel perforation or a bowel blockage. [2]
Common mistakes
- Burned toast or barbecue briquettes are not activated charcoal. They do not adsorb poisons, and some briquettes are treated with chemicals never meant to be swallowed. [2]
- Stomach pumping is rare. Poison Control notes that gastric lavage does not happen very often; most poisonings are treated with supportive care. [2] Do not assume a hospital will "just" do a quick treatment, and do not delay the call.
What to have ready when you call
The product or medicine container, the person's age and rough weight, what and how much may have been swallowed, and when. A step-by-step list is on What to tell Poison Help when you call. If the person is a child, see A child swallowed a supplement or natural product.After the emergency
Poison Control says a person who needs charcoal should be monitored in an emergency room. [2] Tell the care team about every medicine and supplement the person uses. Our page on activated charcoal covers the wellness claims separately.Frequently asked questions
Should I give someone activated charcoal after a poisoning?
No, not on your own. Poison Control says not to try to treat a poisoning with activated charcoal at home. [2] Call 1-800-222-1222 or use the online tool; call 911 for collapse, seizure or trouble breathing. [1]
Can I use charcoal tablets from the store in an emergency?
Poison Control says over-the-counter products might not be as "activated" as hospital charcoal and that the emergency amount would take hundreds of the usual tablets. [2] They are not a substitute for a call.
Does charcoal work for every poison?
The sources we read do not say it does. Poison Control says it can adsorb many types of poison. [2] They do not list which substances it does not help with, so a poison center is the place to ask.
Is charcoal always given in a hospital?
No. A toxicology position paper said single-dose charcoal should not be given routinely. [3] Poison centers and emergency staff decide case by case.
Will Poison Help charge me or share my details?
Poison Control says both online and phone help are free and confidential. [1]
