PubMed indexes 6 records that name Dapsone and Vitamin C 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 Dapsone and Vitamin C. 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.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
“Vitamin C (10 g intravenously) administered 6 hourly successfully treated the dapsone-induced methemoglobinemia and did not adversely affect renal functions. Thus,we recommend that if methylene blue is unavailable, 6 hourly intravenous administrations of 10 g of VC should be considered for dapsone-induced methemoglobinemia.”
Names both Dapsone and Vitamin C in its title.
Names both Dapsone and Vitamin C in its title.
“Intravenous ascorbic acid administration is effective in treating DDS-induced methemoglobinemia in a murine model.”
Names both Dapsone and Vitamin C 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 Dapsone and Vitamin C together in an interaction, co-administration, or pharmacokinetic context.
“With the splenectomy, the number of older erythrocytes in the peripheral circulation increased and resulted in an accumulation of MHb leading to the low oxygen saturations. Her dapsone was immediately stopped and she was started on vitamin C with a 3 day follow up revealing resolution of her methemoglobinemia and normal oxygen saturation on room air.”
Names Dapsone and Vitamin C together in an interaction, co-administration, or pharmacokinetic context.
“On the basis of these data and with the assumption that the exposure to the hydroxylamine is a determinant of dapsone toxicity, we predict that coadministration of fluconazole should decrease the rate of adverse reactions to dapsone in persons with HIV infection but that rifabutin and clarithromycin will have no effect. When dapsone is given in combination with rifabutin, dapsone dosage adjustment may be necessary in light of the increase in dapsone clearance.”

Search-based evidence indexes have real limits, and it is worth being explicit about them:
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 Dapsone, Vitamin C, 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.
NutriStack is an informational and organizational tool, not a medical service, and not a substitute for professional advice. Always consult a qualified healthcare professional before starting, stopping, or changing any supplement or medication.
