OBJECTIVE: To report a case of sulfhemoglobinemia in a patient receiving phenazopyridine for a urinary tract infection. CASE SUMMARY: A 63-year-old white woman presented to the emergency department with complaints of fatigue and bluish discoloration of her body that had gradually progressed over the previous 6–8 weeks. About 4 months prior to presenting to the emergency department, she had started taking phenazopyridine, an over-the-counter medication for symptoms of dysuria. Because the…

Sulfhaemoglobinaemia caused by ferrous sulfate
After a thorough review of his medications, ferrous sulfate was stopped which resulted in resolution in patient’s cyanosis and normalisation of his ABG after 7 weeks.
A Case of Sulfhemoglobinemia Secondary to a Urinary Tract Infection.
A case of SulfHb is presented in an adolescent female with spina bifida and neurogenic bladder in the setting of an Escherichia coli urinary tract infection and the resolution was achieved with antibiotics and red cell transfusion.
Interpreting sulfhemoglobin and methemoglobin in patients with cyanosis: An overview of patients with M‐hemoglobin variants
Measurements of Methemoglobin and sulfhemoglobinemia are useful in the evaluation of cyanosis but when one or both values are elevated, additional analysis is important to establish the etiology of the disorder.
Methemoglobinemia and Sulfhemoglobinemia in Two Pediatric Patients after Ingestion of Hydroxylamine Sulfate
This case report describes two pediatric cases of immediate oxygen desaturation from methemoglobinemia and sulfhemoglobinemia after one sip from a plastic water bottle containing hydroxylamine
On the dysfunctional hemoglobins and cyanosis connection: practical implications for the clinical detection and differentiation of methemoglobinemia and sulfhemoglobinemia.
The causal relationship between these conditions and the onset of cyanosis is investigated and provides the basis for the proposition of a cost-effective protocol for the noninvasive detection and differentiation of these disorders.
On Skin Cyanotic Appearances and Spectral Responses Elicited by Methemoglobinemia and Sulfhemoglobinemia
This thesis investigates the causal relationship between these disorders and the onset of cyanosis and provides the basis for the proposition of a cost-effective protocol for the noninvasive detection and differentiation of these disorders.
Elderly woman with orange urine and purple hands.
A 79-year-old woman with recurrent urinary tract infections presented with complaints of “purple” hands and urine discoloration, apparently induced by 10 days of phenazopyridine use for urinary tract infection.
The Role of Hemoproteins: Hemoglobin, Myoglobin and Neuroglobin in Endogenous Thiosulfate Production Processes
It seems that thiosulfate is a molecule that plays a prominent role in the human body and it is hoped that all these findings will encourage further studies on the role of hemoproteins in the formation of this undoubtedly fascinating molecule and on the mechanisms responsible for its biological activity in thehuman body.

Recognition of the cause of the cyanosis and the specific blood pigment involved permits the separation of conditions connoting serious underlying disease from those of benign origin.
Pitfalls in discriminating sulfhemoglobin from methemoglobin.
The patient was improperly treated with methylene blue, on the basis of an analysis of whole blood by CO-oximetry in which the presence of methemoglobin was reported.

A method for estimating the probability of adverse drug reactions
It was shown that the ADR probability scale has consensual, content, and concurrent validity and may be applicable to postmarketing drug surveillance.
