Activated charcoal
Activated charcoal is carbon from sources such as wood or coconut shells, treated at high heat to give it a very porous surface that binds other substances.
Check medicines before considering it
Charcoal may reduce the effectiveness of medicines, including oral contraceptives and pain relievers, and can cause constipation. Repeated use can also bind vitamins and minerals. Discuss regular use with a pharmacist or clinician. 1
Suspected poisoning needs expert advice
Contact a poison center promptly if someone may have swallowed a poison. Do not give charcoal on your own: cases requiring it need medical assessment and monitoring. 2
Other risks matter too
Charcoal can cause nausea or vomiting. Inhaling the powder or liquid mixture is a particular risk in someone who is very drowsy. Poison Control says it should not be taken with gastrointestinal bleeding, bowel perforation or bowel blockage. 2
