Quantification of Opioid Prescription Practice Changes Due to Hydrocodone Combination Product Rescheduling in an Academic Pain Clinic.

Our study showed a significant decrease in the mean number of HCP prescriptions written per patient, as well as a decrease in the mean number of HCP tablets prescribed. Pain physicians in our clinic increased the number of prescriptions for the non-HCPs. The number of acetaminophen with codeine and tramadol tablets prescribed significantly increased. Therefore, the rescheduling of HCPs has profoundly impacted practices within this academic pain clinic.
