Abstract
We present the case of a 39-year-old male with a past medical history of orthotopic heart transplantation who presented with chest pain and dyspnea on exertion. He was diagnosed with dapsone-induced methemoglobinemia toward the end of his hospital course, and his condition clinically improved with the discontinuation of the offending agent. This case highlights the importance of medication review and history-taking. Clinicians should be mindful of dapsone-induced methemoglobinemia, especially when encountering patients with dyspnea and a history of dapsone intake.
