Phenazopyridine should be used with caution especially for an infant younger than 1 month or with G6PD deficiency because of the risk for methemoglobinemia, sulfhemoglobinemia
, and hemolytic anemia.

The use certain drugs such as sulfonamides are associated with the development of sulfhemoglobinemia
. A sulfur atom attaches to the hemoglobin molecule, preventing the molecule from binding with O2 and causing the dissociation curve to shift to the right.
* Peripheral cyanosis may be caused by pulmonary, cardiac and vascular diseases, enzyme deficiency, methemoglobinemia, sulfhemoglobinemia
, and hemoglobin anomalies.

As a result, a congenital methemoglobinemia attributable to HbM may be mistakenly diagnosed as carbon monoxide poisoning or toxic sulfhemoglobinemia
, as happened with this patient (despite her acknowledgement of a family history of chronic methemoglobinemia at presentation).
 recently described a case of sulfhemoglobinemia
. The exact cause of the dyshemoglobinemia in this patient was not clearly mentioned, but it was probably drug-induced.
is the relatively uncommon condition of excess sulfhemoglobin (SulfHb) in the blood.
