Activated Charcoal and Dapsone: what the published research says
PubMed indexes 6 records that name Activated Charcoal and Dapsone 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.
Every statement below is attributed to a named, dated, linked source.
This page lists published research relevant to Activated Charcoal and Dapsone. 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.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
6 studies naming Activated Charcoal and Dapsone.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Journal of toxicology. Clinical toxicology · 1982 · PMID 7184998
Case ReportsHuman subjects
“This rapid improvement is attributed to interruption by activated charcoal of the enterohepatic circulation of Dapsone. This mode of therapy may be indicated for other compounds having an enterohepatic circulation.”
Names both Activated Charcoal and Dapsone in its title.
Clinical pharmacology and therapeutics · 1980 · PMID 7379451
Clinical TrialRandomized Controlled Trial
“The use of activated charcoal, 80 gm/day for 1 or 2 days, increased (3 to 5 times) the rate of elimination of both dapsone and MADDS, as reflected in serum concentration and urinary excretion data. The use of multiple doses of charcoal seems to be indicated as supplementary treatment of certain intoxications during the postabsorption phase if the drugs have a long t 1/2 and if they are secreted into the gut with subsequent reabsorption.”
Names both Activated Charcoal and Dapsone in its title.
“Twelve of the 14 patients with methemoglobin levels greater than 30% were also treated with a single dose of methylene blue (1-2% solution, 1-2 mg/kg) infused IV over 5 min.RESULTS: There was a progressive decrease in the methemoglobin levels after the beginning of both treatments (multiple doses of activated charcoal alone or associated with methylene blue), and only one dose of methylene blue was necessary.”
Names both Activated Charcoal and Dapsone in its title.
“Acute intoxication from excessive dapsone intake is uncommon and clear treatment guidelines are lacking. We here report the treatment modalities as a result of a dapsone intoxication, including the effects on the overall condition of the patient.”
Names Activated Charcoal and Dapsone together in an interaction, co-administration, or pharmacokinetic context.
“Dapsone clearance was enhanced by ECTR, especially by IHD-HP. However, HP was associated with severe asymptomatic thrombocytopenia.”
Names Activated Charcoal and Dapsone together in an interaction, co-administration, or pharmacokinetic context.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.

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.
