Information about Methylene Blue

Methylene blue uses

Methylene Blue is used in the treatment of Methaemoglobinemia.

How methylene blue works

Methylene blue acts as a reducing agent to reduce methemoglobin to hemoglobin. It is reduced to leucomethylene blue in the red blood cells of our body, by combining with a chemical nicotinamide adenine dinucleotide phosphate (NADPH), in the presence of an enzyme called NADPH reductase. Leucomethylene blue reduces methemoglobin to hemoglobin and restores the oxygen carrying capacity of hemoglobin. This helps in the treatment of Methemoglobinemia.

Nausea, Vomiting, Hemolysis (destruction of red blood cells), Breathlessness, Thrombophlebitis, Anaphylactic reaction, Blue-colored urine and feces
