Methylene blue is given as a 1% solution (10 mg/ml) 1 to 2 mg/kg administered intravenously slowly over five minutes. Although the response is usually rapid, the dose may be repeated in one hour if the level of methemoglobin is still high one hour after the initial infusion. Methylene blue inhibits monoamine oxidase, and serotonin toxicity can ...
The methylene blue allows the methaemoglobin to be converted to haemoglobin. Supportive treatment is also usually provided, depending on the severity of the toxicity, that resulted in the anaemia.

[17] Hemoglobin analysis is important for the diagnosis of alpha-thalassemia as it determines the types and percentages of types of hemoglobin present. [18]
Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.
Blue-green algae can produce toxins that make people and animals sick. It can even cause death in some cases. Four of Lake Geneva's six beaches remain closed due to dangerous blue-green algae
