Both of them reported lowered exercise tolerance after starting dapsone, had pulse oximetry readings of 89% -92%, and methaemoglobin levels of 6.2% and 7% in arterial blood gas analysis. They did not have cyanosis, significant hemolysis or dyspnoea at rest. In both patients, symptoms resolved with cessation of dapsone. lgufxzjojp (cidytmoanf )
