This case involves a female patient who presented to the hospital for a ventral hernia repair. Her doctors opted to use a Kugel mesh. Following her procedure, the patient was prescribed Percocet for pain, despite clear documentation of an allergy to the medication on her preoperative medical clearance note. Before she was anesthetized, the general surgeon on her case specifically asked the patient if she had any allergies and she verbally confirmed that it was on her chart. A few months prior, the patient had a sensitization to Percocet that produced itchiness and dry skin for a three-week duration. During this hospital admission, the patient developed an extremely pruritic dermatological reaction that produced dry scaly skin over her entire body.
