A 52-year-old man with chronic pain due to osteoarthritis of the knees and hips has been prescribed methadone every 8 hours as well as oxycodone PRN. After 3 weeks, he complains of infrequent stools that are difficult to pass. He is prescribed senna along with a recommendation to increase his dietary fiber intake. After 2 weeks, he reports no improvement in bowel movements and complains that he spends an excessive amount of time on the toilet. He also states that sometimes he takes a dose of oxycodone to minimize abdominal pain caused by his constipation. An appropriate next step for this patient is: Change methadone to fentanyl patch Increase the dose of senna Add a bulking agent (e.g., psyllium) to his regimen Initiate treatment with PAMORA Initiate treatment with lubiprostone Next
