- Activated charcoal is a carbon-rich material that has been processed to have an increased surface area. Activated charcoal is widely used for treating drug overdoses and poisonings.
- Activated charcoal is most effective if used within one hour of ingesting toxic substances. It has proven to be effective in both adult and child overdoses of drugs such as acetaminophen, digoxin, digitoxin, tricyclic antidepressants, and barbiturates. However, activated charcoal is not effective in poisonings caused by strong acids or bases, cyanide, organic solvents, ethanol, methanol, iron, or lithium, among other substances.
- Activated charcoal has been traditionally given with laxatives to encourage removal of toxic contents and improve tolerance to charcoal. However, in 2004 and 1997, the American Academy of Clinical Toxicology and the European Association of Poisons Centres and Clinical Toxicologists stated that they do not endorse the combination of activated charcoal with a laxative. This combination may cause serious side effects such as dehydration, electrolyte imbalances, and low blood pressure.
- Activated charcoal has been studied for many stomach disorders, including diarrhea, gas, and indigestion. Research suggests that activated charcoal may benefit people who have diarrhea caused by chemotherapy. When combined with simethicone, activated charcoal may improve symptoms of indigestion. Activated charcoal may also improve bloating and stomach cramps and prevent gas.
- Due to its adsorbing effects (attracts substances to the surface of the material), activated charcoal may help treat liver and kidney disorders. Taking activated charcoal by mouth may lower cholesterol levels and reduce high levels of bile acids. Charcoal may also be given with light therapy to help prevent jaundice (yellowing of the skin) in newborn babies.
- Activated charcoal particles have been studied as a drug delivery system to improve effectiveness of therapies and reduce chemotherapy agent side effects. However, more research is needed in this area.
