Fentanyl iontophoretic transdermal system (ITS) [IONSYS
®
, The Medicines Company, Parsippany, NJ, USA] is a needle-free, patient-controlled, postoperative opioid pain management treatment. It is indicated for the short-term management of acute postoperative pain in adults requiring opioid analgesia in the hospital. The safety and effectiveness of fentanyl ITS for acute postoperative pain management has been demonstrated in a range of surgery and patient types studied in seven phase 3 trials (three placebo-controlled trials and four active-comparator trials). The majority of the patients in the phase 3 trials had undergone either abdominal/pelvic, orthopedic, or thoracic surgery. Consistent with the prescribing information, physicians in clinical practice may treat patients with this system following any type of surgery including those that may not have been included in the phase 3 trials. The purpose of this case series is to illustrate how fentanyl ITS is being utilized for postoperative pain management in real-world clinical practice following a variety of surgeries and in current pain management protocols that may have evolved since the completion of the phase 3 program. There are seven cases from three clinical centers described within this case series, each using fentanyl ITS according to the prescribing information. The surgery types included are bariatric (
N
 = 3), prostate (
N
 = 2), colorectal (
N
 = 1), and perirectal abscess drainage (
N
 = 1). A systematic review of each patient chart was conducted via a standardized retrospective assessment by the clinicians who managed each patient. Additionally, each healthcare professional was interviewed regarding their overall experience and key learnings using fentanyl ITS. Overall, fentanyl ITS was effective and well tolerated in these case reports in current-day clinical practice settings. These case studies are informative about fentanyl ITS use shortly after product approval and set the stage for additional clinical research.
