Overview InformationCommon charcoal is made from peat, coal, wood, coconut shell, or petroleum. “Activated charcoal” is similar to common charcoal, but is made especially for use as a medicine. To make activated charcoal, manufacturers heat common charcoal in the presence of a gas that causes the charcoal to develop lots of internal spaces or “pores.” These pores help activated charcoal “trap” chemicals.
Orally, activated charcoal is used to treat poisonings, reduce phenytoin levels, reduce intestinal gas (flatulence), lower cholesterol levels, prevent diarrhea caused by the cancer drug irinotecan, reduce phosphate levels in dialysis, prevent hangover, calm upset stomach and treat bile flow problems (cholestasis) during pregnancy. Activated charcoal is also used topically in bandages for helping heal wounds and to improve the appearance of skin.
How does it work?Activated charcoal is good at trapping chemicals and prevents their absorption.
Uses & Effectiveness
Possibly Effective for
- Poisoning. Activated charcoal is useful for trapping chemicals to stop some types of poisoning when used as part of standard treatment. Activated charcoal should be given within 1 hour after a poison has been ingested. It does not seem to be beneficial if given for 2 or more hours after some types of poisoning.
Insufficient Evidence for
- Lowering cholesterol levels. So far, research studies don’t agree about the effectiveness of taking activated charcoal by mouth to lower cholesterol levels in the blood.
- Diarrhea caused by the cancer drug irinotecan. Irinotecan is a cancer drug known to cause diarrhea. Early research shows that taking activated charcoal during treatment with irinotecan decreases diarrhea, including severe diarrhea, in children taking this drug.
- Decreasing gas (flatulence). Some studies show that activated charcoal is effective in reducing intestinal gas, but other studies don’t agree. It’s too early to come to a conclusion on this.
- Indigestion. Some early research shows that taking certain combination products containing activated charcoal and simethicone, with or without magnesium oxide, can reduce pain, bloating, and feelings of fullness in people with indigestion. It’s unclear if taking activated charcoal by itself will help.
- Treating reduced bile flow (cholestasis) during pregnancy. Taking activated charcoal by mouth seems to help treat cholestasis in pregnancy, according to some early research reports.
- Lowering phophate levels in people on dialysis. Early research shows that taking activated charcoal daily for 24 weeks might reduce phosphate levels in people on hemodialysis who have high phosphate levels.
- Preventing hangover. Activated charcoal is included in some hangover remedies, but some experts are skeptical about how well it might work. Activated charcoal doesn’t seem to trap alcohol well.
- Toxic effects from the antiseizure drug phenytoin. Some early research shows that activated charcoal can help remove phenytoin from the body, bringing the phenytoin levels back to a normal range.
- Wound healing. Some early research shows that using bandages with activated charcoal does not help with wound healing in people with long-term wounds such as pressure ulcers.
- Other conditions.
Side Effects & SafetyActivated charcoal is safe for most adults when used short-term. Side effects of activated charcoal include constipation and black stools. More serious, but rare, side effects are a slowing or blockage of the intestinal tract, regurgitation into the lungs, and dehydration.
Special Precautions & Warnings:Pregnancy and breast-feeding: Activated charcoal might be safe when used short-term if you are pregnant or breast-feeding, but consult with your healthcare professional before using if you are pregnant.
Gastrointestinal (GI) blockage or slow movement of food through the intestine: Don’t use activated charcoal if you have any kind of intestinal obstruction. Also, if you have a condition that slows the passage of food through your intestine (reduced peristalsis), don’t use activated charcoal, unless you are being monitored by your healthcare provider.
Do not take this combination
Syrup of ipecac interacts with ACTIVATED CHARCOAL
Activated charcoal can bind up syrup of ipecac in the stomach. This decreases the effectiveness of syrup of ipecac.
Be cautious with this combination
Alcohol interacts with ACTIVATED CHARCOAL
Activated charcoal is sometimes used to prevent poisons from being absorbed into the body. Taking alcohol with activated charcoal might decrease how well activated charcoal works to prevent poison absorption.
Medications taken by mouth (Oral drugs) interacts with ACTIVATED CHARCOAL
Activated charcoal absorbs substances in the stomach and intestines. Taking activated charcoal along with medications taken by mouth can decrease how much medicine your body absorbs, and decrease the effectiveness of your medication. To prevent this interaction, take activated charcoal at least one hour after medications you take by mouth.
The following doses have been studied in scientific research:
- For drug overdose or poisoning: 50-100 grams of activated charcoal is given at first, followed by charcoal every 2-4 hours at a dose equal to 12.5 grams per hour. Sometimes a single-dose of 25-100 grams of activated charcoal may be used.
- For drug overdose or poisoning: Activated charcoal 10-25 grams is recommended for children up to one year of age, while activated charcoal 25-50 grams is recommended for children 1-12 years of age. Activated charcoal 10-25 grams is recommended if multiple-doses of activated charcoal are needed.
