Activated charcoal is a ok , black powder that ’s very good at grabbing hold of chemicals , which is why it ’s usually usedto care for poisoning . Some hoi polloi use activated charcoal in an attempt to reduce gas and bloating , to forestall holdover , or to " clean " the digestive tract — although there islittle to no scientific evidenceto back up these claim . And thanks to its ability to sprain nutrient and drinks calamitous , activated charcoal is also a popular food coloring agent , particularly around Halloween .
What many people do n’t realise , however , is thatactivated charcoalcan intervene with sure medications by tighten how much of the drug come into the blood stream , fall its effectivity .
Activated charcoal, also called activated carbon, can mess with the absorption of drugs in the body.
But how does spark charcoal interact with medications ?
The primary mechanism behind this interaction is surface assimilation , Lingtak - Neander Chan , a professor of pharmacy at the University of Washington , evidence Live Science in an e-mail . Adsorption is a unconscious process by which mote stick to the open of a material . Thanks to its unbelievably poriferous structure , activate oxford gray has a large surface area that makes it extremely effective at adsorbing — or holding on to — drug molecules on its surface .

" This basically mapping like a fishing net , " Chan said , because the activated charcoal grey trap drug molecules in the gut .
When a drug is ingested — for representative , in a pill or swimming form — it must die through the lining of the intestine in rescript to enter the blood stream . From there , it exerts its impression on the body . But if spark fusain is present in the digestive tract , the drug molecule stay in the bowel and are eventually excreted , together with the aerate charcoal .
In sure instances , the consequences of this interaction can be serious . A report published in the journalThe Lancetdescribed a case in which spark charcoal interfered with platelet - lowering medicine ; blood platelet are the part of the origin creditworthy forclotting . This interference rendered the drug ineffectual in a patient role with heart disease .
In another case , document in the journalAntiviral Therapy , activated charcoal interfered with antiretroviral drugs , which are used to treatHIV . This glower the engrossment of drug in the blood stream , leading to a rebound in viral encumbrance — the number of computer virus particle in the body . Ideally , antiretrovirals drive down the amount of HIV in the bodyuntil it ’s insensible . The patient also grow electric resistance to their medicament because these too - low drug compactness start the virus to outlive , accommodate and then continue replicating .
According to themedical resourcefulness StatPearls , activated charcoal limits concentration of a wide range of drug , include mutual painkillers , downer and antidepressant . The big a drug particle is , the more probable it will be take in by activated charcoal , Chan noted . Some hormone - base drug , including birth control pills , can be get by activated charcoal for this intellect .
On the other hand , medications that have strong ionic charges — meaning they have very positive or very minus electrical charge — do n’t tend to bind well with charcoal grey . These include medications likelithium , used in the treatment of bipolar disorderliness , and oral iron supplementation . These substances are still absorbed efficiently when touch off charcoal is in the gut .

Not all drug within the same stratum are affected equally by activated charcoal .
" This is because the adsorption effect depends on the physical characteristics and the size of the drug molecules , " Chan explained . For example , one blood - press medication might adsorb to activate charcoal , while another in the same class might not . So it ’s unmanageable to make sweeping statements about potential drug interactions .
Timing is all important for void activated charcoal ’s fundamental interaction with drugs . The adsorption effect is strongest when both the drug and the fusain are have within an time of day of each other , Chan say . In the emergency brake department , it ’s often used if a patient is suspected of having take in poison less than an time of day or two prior to price of admission , he order .
Another divisor to consider is the dose of activated charcoal . In cases where it ’s used to process intoxication , the typical VD is 1 gram per kilogram of body weightiness , according to Chan . This ensures maximum adsorption of the ingested toxic substance . The amount of trigger charcoal establish in trendy household product , such as some toothpastes and foods , is comparatively small — " much low than 1g / kg in most casing , " he said . That make it less likely to intervene with medications .

People who use activated charcoal for role other than treating toxic condition — such as for alleged intestine cleansing or detox — should pay attention to how much charcoal they are have and the time between when they take the activated charcoal gray and when they take medications , Chan advise . Consult a health caution provider if you ’re taking both activated charcoal and medicine .
