Related to Toluidine Blue: methylene blue, toluidine blue dye
A toxic metachromatic thiazine dye used to stain ‘thick’ sections for electron microscopy, which may cause haematuria due to haemorrhagic cystitis and methaemoglobulinuria. Toluidine blue should be avoided by patients with glucose-6-phosphate deficiency, given their risk of haemolytic anaemia
