A 24-year-old man presents to the emergency department with a 2-day history of fever, malaise, and boils on his right leg. He is a competitive swimmer and reports that he borrowed a teammate's razor to shave his legs before a swim meet. Past medical history is unremarkable. Physical examination shows 3 raised, erythematious, warm, lesions with a central point extruding pus. A Gram stain and culture are performed and reveal that the causative organism is a catalase-positive, Gram-positive coccus. The organism also tests positive for the MecA gene. The patient is prescribed oral linezolid to treat this patient.

Which of the following is a potential adverse effect of this intravenous antibiotic?

  • A) Flushing
