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. Plaquenil appetite loss Hydroxychloroquine alopecia Plaquenil brain fog Dermatomyositis hydroxychloroquine rash Initial attempts to combine methylene blue with chloroquine were evidently not effective in treating patients with malaria in Africa. Another advantage of using methylene blue in combination with antimalarial drugs is its activity against the gametocyte stages, which can reduce the transmission of P. falciparum. Key words methylene blue; lumefantrine; pyrimethamine; Plasmodium berghei; resistant; parasitaemia. sensitizes the parasite for chloroquine action 32,33. Depletion which sensitizes the parasite for chloroquine action. Methylene blue is a non-competitive inhibitor of P. falciparum glutathione reductase with a. 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).

Methylene blue MB has a similar mode of action as chloroquine CQ and has moreover been shown to selectively inhibit the Plasmodium falciparum glutathione reductase. Falciparum, synergistic activity when combined with artemisinin and related endoperoxides, but antagonistic effects with chloroquine and other. Methylene blue was found to target gametocytes produced from Indian field isolates and is proposed to be used as a gametocytocidal adjunct with artemisinin-based combination therapy. Further exploration of methylene blue in clinical studies amongst Indian population, including G6PD deficient patients, is recommended.
