What is Activated charcoal and its benefits
What is Activated charcoal?
Activated charcoal, often called activated carbon, is a black, tasteless, and odorless powder that has been relied on for medicinal purposes since the beginning. Charcoal that has undergone a high-temperature oxygen treatment process to increase its porosity is known as activated charcoal. This procedure alters its internal structure, resulting in smaller pores and a larger surface area.
A description of charcoal’s adsorbent qualities dates back to the 1700s.In 1811, French chemist Michel Bertrand reportedly consumed charcoal and 5 g of arsenic trioxide for the first time as an antidote.
This article describes some information about activated charcoal, how it functions, what health advantages are supported by science, any associated risks, and any adverse effects.
Mechanism of action
- Toxins consumed are adsorbed by activated charcoal in the digestive tract, blocking their systemic absorption.
- Only poisons dissolved in a liquid can be directly taken away by activated charcoal.
- It comes into touch with ingested poisons if the medication is still not absorbed from the stomach or intestine.
- Activated charcoal taken orally operates in the gastrointestinal (GI) tract unaltered as it is not absorbed by the gut.
Recommended dosage of activated charcoal
- It is available as both suspension and powder suspension.
- If activated charcoal hasn’t been blended, a slurry can be created by combining it with a suitable liquid of 1 to 8, such as water, cola, or flavored syrups.
- It is given in a Single dose of Activated charcoal (SDAC) or Multiple doses of Activated charcoal (MDAC) based on the substance that caused the poisoning.
Single dose Activated charcoal (SDAC)
- Infants from birth to 1 year – 10 to 25 g
- Children – 2 to 12 years – 25 to 50 g
- Teenagers and adults – 50 to 100 g
Multiple-dose activated charcoal (MDAC)
- Refers to two or more successive doses of activated charcoal for improved toxin removal.
- Kids till 13 years – first dose of 10 to 25 g, then subsequent dosing is based on body weight.
- Teenagers and adults – initial dose of 25 to 100 g, then repeated doses of 10 to 25 g for every 2 to 4 hours
For oral use
- Ready-to-use formulations with sorbitol already added, as well as 15 g, 25 g, and 50 g dosages of aqueous activated charcoal suspension available.
- To preserve the product’s properties, activated carbons must be stored and shielded from moisture.
- Additionally, it should be stored away from solvents to prevent the chance of activated carbon absorbing their fumes or vapors.
- Liquid oxygen, ozone, and strong oxidants that can ignite quickly are incompatible substances and should be kept away.
Benefits of activated charcoal
- Activated charcoal can be taken internally to stop poisoning by trapping medicines and other substances. It should only be used when instructed by a medical practitioner, along with standard poisoning treatments.
Activated charcoal frequently aids in the removal of contaminants and medications such as:
- Calcium channel blockers.
- Tricyclic antidepressants.
- Other inorganic and organic materials.
Other health benefits may include
- Fish odor syndrome or trimethylaminuria (TMAU) – Activated charcoal may aid people with fish odor syndrome, a condition in which the body builds up trimethylamine (TMA). This substance has a fishy stench. ,
- Kidney disease – According to a study conducted on older adults, activated charcoal may aid in improving kidney function in those with chronic renal disease and lower urea and creatinine blood levels.
- Intestinal gas – Activated charcoal can be used to reduce excessive gas formation, according to a panel of the European Food Safety Authority (EFSA), whose research is still in its early stages
- Diarrhea – Researchers concluded that by trapping harmful germs and medications on its porous, rough surface, it would be able to limit their absorption into the body and cause diarrhea.
- In food – Toothpaste and ice cream are two products that include activated charcoal.
- Various home remedies – Additionally, although many individuals use it as a home cure for various issues, like water purification, skin treatment, and tooth whitening, there is scant scientific evidence to back up these claims.
- Purification of medicines, injectable fluids, contrast media, paracetamol, and vitamins are just a few examples of solutions purified using activated carbon.
It is often regarded as safe to use. The most frequent side effects could be
- A dark-tarred stool.
What other risks are associated with activated charcoal?
Although there are not many known adverse effects of using activated charcoal, there are still some risks, as follows:
- When receiving activated charcoal, unconscious patients risk aspirating vomit or wrongly inserted nasogastric tubes, which can cause aspiration pneumonitis, severe respiratory problems, and occasionally even death.
- Intestinal blockage may be more likely in patients who have already developed motility issues, are on opioids or antimuscarinic medications, or are being treated with MDAC.
- Some activated carbons are available as powders. Therefore, it is essential to prevent inhaling this dust, skin and eye contact, generation, and distribution of dust.
- Additionally, activated carbons draw oxygen from the air, lowering the oxygen available for breathing; hence, people should store them in adequately ventilated areas.
- Activated charcoal shouldn’t be given before the endoscopy operation because it could impair endoscopic visibility.
- It shouldn’t be used to treat all poisoning because it is ineffective at getting rid of some toxins such as metals, acids, alkalis, electrolytes, alcohol, and petroleum compounds.
- Before taking activated charcoal, pregnant women and nursing moms should speak with a doctor.
Interactions of activated charcoal
The following products may interact when used with activated charcoal:
- The stomach and intestines absorb fewer drugs and other chemicals when activated charcoal is present, thus decreasing the effects of the medicines.
Birth control pills
- The amount of birth control pills the body absorbs might be reduced by taking activated charcoal along with them, thus decreasing its efficiency.
- To prevent this interaction, use activated charcoal at least three hours after or twelve hours before taking birth control pills.
- Consuming alcohol and activated charcoal may make it less effective at preventing poison absorption.
- Can be bound by activated charcoal in the stomach. This lessens the effects of ipecac syrup.
Not all medications which interact with activated charcoal are listed above. Before using activated charcoal, it is advised that the patient discuss all medications, including prescription, over-the-counter, herbal, and other supplements, to avoid any potential interactions.
The bottom line
Like any other active substance or medicine, activated charcoal should be cautiously handled. Although it has been utilized for various health benefits, only a small number of them are supported by science, and many claims still need more investigation to be proven true. Before using activated charcoal to back up any of its health claims, it is best to talk with a doctor about the dangers and advantages.
