AbstractIntractable nausea can occur in numerous settings. We report on a 49-year-old woman with a past medical history of cystic fibrosis (CF) with chronic hypoxia, chronic nausea, complex infection history and frequent hospitalizations who was admitted to an academic medical center with a CF exacerbation. Her chronic nausea worsened with the use of antimicrobials, and she was unable to tolerate dopamine or serotonin antagonist antiemetics. Nausea persisted despite the use of benzodiazepines and antihistamines. She was given a one-time dose of fosaprepitant 150 mg intravenously (IV) with marked improvement of her nausea. During subsequent exacerbations, she again developed severe nausea which continued to respond well to a one-time dose of fosaprepitant 150 mg IV. Fosaprepitant is a substance P/neurokinin-1 (NK1) receptor antagonist that is FDA-approved for the prevention of chemotherapy-induced nausea and vomiting and has been used to prevent post-operative nausea and vomiting. Its use in other contexts has not been well established. This case suggests a role for fosaprepitant in the management of nausea outside the context of chemotherapy or general anesthesia.
