Activated Charcoal and Triclabendazole

Here is the interaction we found between these two, with the evidence behind it.

Major

ORAL DRUGS

Why this applies to Triclabendazole

Triclabendazole falls under ORAL DRUGS — the group Activated Charcoal interacts with.

Activated charcoal reduces systemic exposure to many drugs, including those that undergo enterohepatic recirculation, regardless of the route of administration.
Activated charcoal adsorbs various drugs and may reduce their absorption and/or half-life. Examples of affected drugs include acetaminophen, aminophylline, amiodarone, atenolol, carbamazepine, dapsone, digoxin, disopyramide, fluoxetine, indomethacin, moxifloxacin, nadolol, phenytoin, phenobarbital, piroxicam, quinine, sotalol, theophylline, tricyclic antidepressants, valproate, and verapamil. Avoid co-administration, except after drug overdose.
Severity Major Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: activated charcoal acts like a sponge in your gut, grabbing onto medicines before your body can absorb them. If you swallow it around the same time as triclabendazole (Egaten), less of the drug is likely to make it into your bloodstream. Since triclabendazole needs to reach a good level in your body to actually kill the liver flukes, that could mean a weaker effect and a treatment that doesn't fully clear the infection.

This is a short course of medicine you usually take with food, so you really want it working at full strength. I'd avoid taking charcoal supplements anywhere near your dose. If you feel you need charcoal for some reason, please check with your pharmacist or doctor first so they can space things out or guide you.

About Activated Charcoal

What is Activated Charcoal?

Activated Charcoal
  • Poisoning and drug overdose (in emergency care)
  • Gas and bloating
  • Upset stomach
  • Diarrhea
  • Teeth whitening
  • General 'detox'

Activated charcoal is a highly porous form of carbon that can bind certain substances in the gut, and it is used in hospitals to treat some poisonings and overdoses. For everyday uses like gas, bloating, detox, or teeth whitening, the evidence is weak or unclear. If you suspect a poisoning, call your local poison control center or seek emergency care first rather than using a home product.
