Activated Charcoal and Digoxin: what the published research says

PubMed indexes 8 records that name Activated Charcoal and Digoxin together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Activated Charcoal and Digoxin. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Activated Charcoal and Digoxin.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Activated charcoal increases digoxin elimination in patients.

International journal of cardiology · 1995 · PMID 7744534

Clinical Trial

“34 ml/min; 95% C.I. 83-113 ml/min) for the group receiving charcoal, representing an 78% increase in digoxin elimination.”

IbaƱez et al. · From the abstract

Names both Activated Charcoal and Digoxin in its title.

Acceleration of digoxin clearance by activated charcoal.

Clinical pharmacology and therapeutics · 1985 · PMID 3978996

Clinical TrialRandomized Controlled Trial

“Kinetic predictions would suggest greater proportional increases in digoxin clearance in patients with renal impairment. We conclude that repeated doses of charcoal enhance the clearance of digoxin and should be considered for use in digoxin toxicity.”

Lalonde et al. · From the abstract

Names both Activated Charcoal and Digoxin in its title.

The effects of activated charcoal on digoxin and digitoxin clearance.

Drug intelligence & clinical pharmacy · 1985 · PMID 4085353

Clinical TrialRandomized Controlled TrialResearch Support, U.S. Gov't, Non-P.H.S.

“We conclude that the activated charcoal regimen is probably useful in patients with digitoxin toxicity. Although similar benefit is limited in patients with normal renal function who develop digoxin toxicity, it is possible that activated charcoal will be useful in patients with prolonged digoxin elimination due to renal dysfunction.”

Park et al. · From the abstract

Names both Activated Charcoal and Digoxin in its title.

Reduction of absorption of digoxin, phenytoin and aspirin by activated charcoal in man.

European journal of clinical pharmacology · 1978 · PMID 668776

Clinical TrialRandomized Controlled Trial

“When activated charcoal was ingested 1 hour after the drugs the inhibition of absorption was considerably less. However, since the absorption of larger doses of the drugs is often slow, the administration of an adequate dose of activated charcoal will be of definite value in the treatment of acute intoxication, even if delayed for several hours.”

Neuvonen et al. · From the abstract

Names both Activated Charcoal and Digoxin in its title.

Effects of multiple doses of montmorillonite, alone and in combination with activated charcoal, on the toxicokinetics of a single dose of digoxin in rats.

Iranian journal of basic medical sciences · 2023 · PMID 37427323

“Multiple-dose of montmorillonite reversed digoxin toxicity and reduced serum digoxin levels by increasing the excretion and reducing the half-life. Montmorillonite has also corrected digoxin-induced hyperkalemia. Based on the findings, a multiple-dose regimen of oral montmorillonite could be a suitable candidate for reducing the toxicity issue associated with drugs like digoxin that undergo some degree of enterohepatic circulation.”

Heydarian et al. · Authors' conclusion

Names both Activated Charcoal and Digoxin in its title.

Systematic review on the use of activated charcoal for gastrointestinal decontamination following acute oral overdose.

Clinical toxicology (Philadelphia, Pa.) · 2021 · PMID 34424785

Systematic ReviewHuman subjects

“This systematic review found heterogenous data. The higher GRADE data was focused on a few select poisonings, while studies that addressed patients with unknown and or mixed ingestions were hampered by low rates of clinically meaningful toxicity or death. Despite these limitations, they reported a benefit of activated charcoal beyond one hour in many clinical scenarios.”

Hoegberg et al. · Authors' conclusion

Names Activated Charcoal and Digoxin together in an interaction, co-administration, or pharmacokinetic context.

Antidotes for acute cardenolide (cardiac glycoside) poisoning.

The Cochrane database of systematic reviews · 2006 · PMID 17054261

Systematic ReviewHuman subjects

“There is some evidence to suggest that MDAC and anti-digoxin Fab antitoxin may be effective treatments for yellow oleander poisoning. However, the efficacy and indications of these interventions for the treatment of acute digitalis poisoning is uncertain due to the lack of good quality controlled clinical trials.”

Roberts et al. · Authors' conclusion

Names Activated Charcoal and Digoxin together in an interaction, co-administration, or pharmacokinetic context.

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Activated Charcoal, Digoxin, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
