Activated Charcoal for Poisoning
(CHARPP-Pilot Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether activated charcoal can treat poisoning by preventing toxins from worsening and reducing hospital stays. Participants divide into two groups: one receives activated charcoal, and the other receives standard care. The trial aims to determine if activated charcoal can improve recovery and allow patients to return home sooner. Individuals who have ingested a toxic substance within the last six hours might be suitable candidates for this study.
As a Phase 4 trial, this research seeks to understand how the already FDA-approved and effective treatment benefits more patients, offering a chance to contribute to broader medical knowledge.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What is the safety track record for activated charcoal?
Studies have shown that activated charcoal is generally safe for short-term use. It often helps remove toxins from the stomach in cases of poisoning. Common side effects include mild nausea or vomiting. Research indicates that the benefits of using activated charcoal can outweigh these risks, especially when used soon after poisoning occurs.
One study found that activated charcoal effectively treats people who have been poisoned. However, there is a risk of vomiting and accidentally inhaling material into the lungs, particularly if the poisoning is not severe. Overall, activated charcoal is well-tolerated and can be a useful tool in managing certain types of poisoning.12345Why are researchers enthusiastic about this study treatment?
Activated charcoal is unique because it offers a fast and straightforward way to manage poisoning by preventing the absorption of toxins in the stomach. Unlike other treatments that might require more invasive procedures or longer timeframes to take effect, activated charcoal can be administered quickly and is effective almost immediately. Researchers are excited about its ability to be mixed with a familiar black soft drink, making it easier for patients to take, which can improve adherence to the treatment. This quick action and ease of use make activated charcoal a standout option for treating poisoning.
What evidence suggests that activated charcoal is effective for acute poisoning?
Research shows that activated charcoal can help treat poisonings when used properly. It can reduce the absorption of certain poisons, like paracetamol, if taken soon after ingestion. In this trial, participants in one arm will receive activated charcoal, which studies have shown can lower drug levels in the blood. However, it did not significantly affect hospital stay duration or survival chances. Another study found a slight improvement in survival rates with multiple doses, but the results were not strong. Although activated charcoal is commonly used for poisonings, controlled studies have not proven it changes overall outcomes. Nevertheless, it remains a standard treatment for certain poisonings because it can bind to toxins in the stomach.15678

Are You a Good Fit for This Trial?
This trial is for adults and children who arrived at the hospital within 8 hours after ingesting a potentially toxic dose of a substance that can be absorbed by activated charcoal. It's not specified who cannot participate, but typically there would be criteria excluding certain individuals.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive either activated charcoal or standard supportive care. Activated charcoal is administered at 1g/kg up to a maximum of 50g, either orally or via naso-gastric tube.
Follow-up
Participants are monitored for progression of toxicity and other relevant outcomes. Follow-up is conducted every 8 hours by the poison centres.
Long-term follow-up
Functional outcomes and adverse events are documented, including the ability to return to daily activities and manage personal hygiene tasks independently.
What Are the Treatments Tested in This Trial?
Interventions
- Activated Charcoal
Trial Overview
Researchers are testing if giving activated charcoal to patients with acute poisoning is better than standard supportive care alone. They want to know if it prevents worsening of toxicity, shortens hospital or ICU stays, and improves patient outcomes like independence in daily activities.

Experimental Treatment
Active Control
Participants will receive 1g/kg up to a maximum of 50g of activated charcoal by mouth or by naso-gastric tube. The intervention is giving over 15 minutes, as recommended. Activated charcoal can be mixed in a black soft drink to improve palatability and treatment adherence which is often done in usual practice.
Participants will not receive any activated charcoal
