Poppers-Induced Methemoglobinemia: A Curious Case of the Blues.

Methemoglobinemia (MetHb) can be a deadly condition at certain levels, presenting in a fulminant form of cyanosis or disguising itself with vague symptoms. Methemoglobinemia is an altered state of the body's hemoglobin, which can be congenital or acquired. We report a case of a 62-year-old male who presented with altered mental status and hypoxia after consuming "Jungle Juice", raising concern for methemoglobinemia. A diagnosis of methemoglobinemia was confirmed with arterial blood gas and guidance from New York State poison control. The patient was adequately treated with the antidote methylene blue with a resolution of symptoms. We highlight that methemoglobinemia can present itself in various forms and that early recognition and treatment can prevent fatal outcomes.
