Cocaine-Induced Raynaud's Phenomenon: A Case Report

We illustrate a notable case of a middle-aged male who presents to a community hospital with left third- and fourth-digit discoloration and pain for the past four days. On presentation to the emergency department, a urine drug screen was ordered which showed synthetic cannabinoids, cocaine, and amphetamines. Initial therapy of nitroglycerin paste, oral oxycodone, intravenous Dilaudid®, and aspirin was started, which resulted in decreased subjective pain. The pathophysiology and mechanism of cocaine-induced Raynaud's phenomenon (RP) are discussed. Our purpose in putting forward this case is to acknowledge cocaine use as a cause of secondary RP and to emphasize the importance of early recognition to reduce the occurrence of digital necrosis.
