Real-World Use of Activated Charcoal in Pediatric Poisoning: Appropriateness, Adherence, Practice Patterns, and Clinical Outcomes
This retrospective study of pediatric emergency department patients reveals that while activated charcoal and gastric lavage are frequently administered inappropriately relative to current guidelines, nearly all patients receive a clinically meaningful dose, with older age and suicidal intent significantly predicting higher adherence and the use of gastric lavage.

Every year, thousands of children arrive at emergency rooms after swallowing something they should not have. Sometimes this happens by accident, as a curious toddler finds a bottle of medicine. Other times, it is a deliberate act of self-harm by an older child or teenager. For decades, the standard response to such incidents involved a specific medical tool: activated charcoal. This is a fine, black powder that looks like soot but is made from materials like coconut shells or wood. When a child swallows it, the powder acts like a sponge inside the stomach and intestines, trapping toxins before they can pass into the bloodstream and cause harm. Because of this ability, doctors once gave it to almost every child who came in after a poisoning. However, as medical knowledge has grown, experts have realized that this sponge does not work for every poison, and it is not always helpful if too much time has passed since the child swallowed the substance. Consequently, major medical groups now recommend using it only in specific situations, rather than as a routine treatment for everyone.
Despite these updated guidelines, doctors in busy emergency rooms often continue to use the old approach. A new study from Turkey sought to understand exactly how this treatment is being used in the real world, particularly for children and teenagers. The researchers looked back at the medical records of 173 young patients who had received the charcoal treatment at a large hospital between 2019 and 2025. Their goal was to see if the doctors were following the current rules, whether the children actually swallowed the full dose of the powder, and what happened to them afterward. They wanted to know if the treatment was being given to the right people at the right time, or if old habits were keeping the practice out of step with modern science.
The study revealed that the way doctors are currently treating these patients often does not match the official recommendations. In nearly one-third of the cases, the charcoal was given when it likely was not needed. This usually happened because the child had swallowed a small amount of a substance that was not dangerous, or because the powder was given to a child who had swallowed a substance that the charcoal cannot trap, such as iron. The researchers found that doctors often made these decisions based on uncertainty or concern from parents, rather than on strict evidence of danger. While the intention was to be safe, the result was that many children received a treatment that offered them no real benefit.
The study also examined how well the children could actually swallow the medicine. The charcoal powder has a very bitter, gritty taste that many children find difficult to tolerate. The researchers found that only about one-third of the patients managed to drink the entire dose prescribed to them. However, the story did not end there. Even among the children who did not finish the full dose, almost all of them still managed to swallow at least half of it. This suggests that while the treatment is unpleasant, it is rarely refused completely. The ability to swallow the full dose depended heavily on the age of the child. Older teenagers were much more likely to drink the entire amount compared to younger children. This difference was also linked to why the child had taken the substance in the first place. Teenagers who had taken the medicine intentionally were more likely to cooperate with the treatment than younger children who had taken it by accident.
Another part of the study looked at a more invasive procedure called gastric lavage, which is essentially washing out the stomach with water through a tube. Current medical guidelines advise against this procedure for most poisoning cases because it carries risks and has not been shown to improve outcomes. Yet, the researchers found that two out of every three children in their study had their stomachs washed out. This happened more often when the child had swallowed a dangerous amount of poison, was older, or had taken the substance intentionally. The doctors seemed to be choosing this aggressive method for the patients they perceived to be at the highest risk, even though the guidelines suggest it should be avoided.
The children in the study mostly fell into two groups. The younger ones, mostly toddlers, had accidental poisonings, while the older ones, mostly teenage girls, had taken the substances on purpose. The substances involved were often common medications, such as antidepressants or pain relievers. Most of the children left the emergency room within a day, and tragically, none of them died or suffered from the charcoal getting into their lungs during the study period. The fact that no serious complications occurred is reassuring, but the high rate of unnecessary treatments remains a concern.
The researchers concluded that while the charcoal treatment is generally safe, it is being used too broadly. Doctors are frequently giving it to children who do not need it and are performing stomach washes more often than the rules suggest. The study highlights that while older children are better at taking the medicine, the practice of giving it to everyone needs to change. To improve care, doctors may need better tools to decide exactly when the treatment is necessary, rather than relying on general caution. The goal is to ensure that every child receives the right care for their specific situation, avoiding unnecessary procedures while still protecting those who are truly at risk.
