Concurrent Use of Pregabalin with Opioids

Introduction to Risks

The American College of Physicians recommends avoiding concurrent use of pregabalin with multiple opioids, such as morphine and oxycodone, due to increased risk of respiratory depression, sedation, and other serious adverse effects 1

The National Comprehensive Cancer Network suggests that using a single opioid at an appropriate dose can minimize risks, and pregabalin can be effectively combined with a single opioid for neuropathic pain management 2
Pregabalin requires dose adjustment in patients with renal impairment, and can cause dose-dependent dizziness and sedation, which would be worsened by concurrent use of multiple opioids 2

The Mayo Clinic recommends starting with reduced doses of all medications to account for potential additive effects, and monitoring respiratory rate, sedation level, and other vital signs more frequently when concurrent use is necessary 1
The FDA warns that pregabalin can increase the risk of respiratory depression when combined with opioid pain medicines, and recommends using this combination for the shortest duration possible to minimize risks 1

Specialists familiar with complex pain management should be aware that concurrent use of multiple opioids with pregabalin can lead to dangerous oversedation, and should limit this practice to only when necessary 1
