Methemoglobinemia is a condition in which the iron within hemoglobin is oxidized from the ferrous (Fe2+) state to the ferric (Fe3+) state, resulting in the inability to transport oxygen and carbon dioxide. Clinically, this condition causes cyanosis, often posing a diagnostic dilemma
usually results from exposure to oxidizing substances (such as nitrates or nitrites, aniline dyes, or medications, including lidocaine, prilocaine, phenazopyridine hydrochloride (Pyridium], and others)
