Methemoglobinemia may not resolve or may rebound after initial response to therapy with methylene blue in patients with methemoglobinemia associated with aryl amines (e.g., aniline) or sulfa drugs (e.g., dapsone). Has been used as a photosensitizer for photodynamic therapy† (PDT) for topical treatment of dermatologic or mucocutaneous infections (e.g., herpes labialis, eczema herpeticum, oral candidiasis, cutaneous leishmaniasis, chromoblastomycosis) When sodium nitrite is used for cyanide poisoning, do not use methylene blue in an attempt to treat excessive methemoglobinemia induced by the antidote because reduced cyanide binding and increased toxicity occurs.

In Vitro Assessment of Methylene Blue on Chloroquine-Sensitive and -Resistant Plasmodium falciparum Strains Reveals Synergistic Action with Artemisinins. The antagonistic actions of chloroquine and methylene blue were also shown for the chloroquine-sensitive strain. Artemisinins target the SERCA of Plasmodium falciparum. Nature 47-961. Methylene blue MB combined with chloroquine CQ has been considered as one promising new regimen. The primary objective of this study was to evaluate the safety of CQ-MB in African children with uncomplicated falciparum malaria. Secondary objectives were to assess the efficacy and the acceptance of CQ-MB in a rural population of West Africa. Most cases of serotonin syndrome occurred when methylene blue was used as a diagnostic (visualizing) dye† (1–8 mg/kg IV) during parathyroid surgery in patients receiving a serotonergic drug; unclear whether there is a risk when methylene blue administered by other routes or in lower IV doses. (See Boxed Warning.) Manifestations of serotonin syndrome may include mental changes (e.g., confusion, hyperactivity, memory problems, agitation, hallucinations, delirium, coma), autonomic instability (e.g., tachycardia, labile BP, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or GI symptoms (e.g., nausea, vomiting, diarrhea).

In vitro assessment of methylene blue on chloroquine‐sensitive and. et al. Efficacy and safety of triple combination therapy with artesunate‐amodiaquine‐methylene blue for falciparum malaria in children a. Methylene blue for treating malaria. Safety of the methylene blue plus chloroquine combination.. Methylene blue induced morphological deformations in.. Methylene blue has a similar mode of action as chloroquine and has moreover been shown to selectively inhibit the Plasmodium falciparum glutathione reductase. The mature gametocytes of Plasmodium are solely responsible for parasite transmission from the mammalian host to the mosquito. Early and late stage P. falciparum gametocyte cultures 2% haematocrit, 5% gametocytaemia were treated with compounds at 1 and 5 μM primary dual-point primary screening, with methylene blue 5. The geometric mean 50% inhibitory concentration IC 50 for Proveblue, a methylene blue complying with the European Pharmacopoeia, was more active on 23 P. falciparum strains than chloroquine, quinine, mefloquine, monodesethylamodiaquine, and lumefantrine.
