DEA X-Waiver and Buprenorphine

A 20-year-old man is brought to the emergency department (ED) by his family for evaluation. His family reports that he failed out of school in his second year at a local community college. He admits to escalating struggles with prescription pain pills (prescription opioids), and then heroin use. He appears to be in opioid withdrawal; he describes anorexia and diarrhea, and is yawning and sweating on exam. He has a Clinical Opioid Withdrawal Scale (COWS) score of 15, indicating moderate withdrawal. His provider orders clonidine, ondansetron, and 2/0.5 mg sublingual buprenorphine/naloxone, with a plan to observe him in the ED. The provider subsequently receives a concerned call from the hospital pharmacist.

Question: The Pharmacist States That the Provider is Unable to Administer Buprenorphine in the ED Without an X-Waivered DEA Number. Is This Accurate?

Title: Buprenorphine Administration in the ED: The Role of X-Waivered DEA Numbers


The scenario described above illustrates a common situation encountered in emergency departments across the United States – a young adult seeking help for opioid withdrawal. In this case, a 20-year-old man is experiencing moderate opioid withdrawal symptoms after a history of prescription opioid and heroin use. The provider’s plan to administer clonidine, ondansetron, and sublingual buprenorphine/naloxone is an evidence-based approach to manage opioid withdrawal effectively. However, a concern arises when the hospital pharmacist suggests that the provider cannot administer buprenorphine in the ED without an X-waivered DEA number. This essay aims to clarify whether this assertion is accurate and to provide insights into the Drug Enforcement Administration (DEA) regulations regarding buprenorphine administration in emergency settings.

Buprenorphine: An Essential Tool in Opioid Withdrawal Management

Buprenorphine/naloxone, a combination medication, has emerged as a vital component in the treatment of opioid use disorder (OUD). It is a partial opioid agonist that helps alleviate withdrawal symptoms and cravings while reducing the risk of overdose. The use of buprenorphine in the ED for opioid withdrawal management has been endorsed by medical societies and is consistent with the principle of providing prompt, evidence-based care to patients in crisis.

DEA X-Waiver and Buprenorphine

To understand the role of the X-waiver in buprenorphine administration, we must first define what it represents. The Drug Addiction Treatment Act of 2000 (DATA 2000) authorized qualified physicians to obtain a waiver from the DEA to prescribe Schedule III, IV, or V narcotic medications for the treatment of OUD. Buprenorphine is a Schedule III controlled substance, and physicians with an X-waiver can prescribe it for maintenance or detoxification treatment.

The Controversy Surrounding X-Waiver Requirement

Historically, the X-waiver requirement was seen as a barrier to expanding access to buprenorphine treatment. Many healthcare professionals, policymakers, and addiction specialists believed that it limited the number of qualified providers and hindered efforts to address the opioid epidemic effectively. As a response to this concern, regulations were changed in April 2021 to reduce some of the restrictions associated with the X-waiver, including the requirement for additional training.

Buprenorphine Administration in the Emergency Department

The scenario described involves a patient in the emergency department experiencing opioid withdrawal. Under the revised regulations, physicians with an active DEA registration can administer buprenorphine for up to 72 hours to relieve acute withdrawal symptoms without needing an X-waiver. The intent behind this change was to increase access to buprenorphine in emergency settings and ensure that individuals in crisis receive immediate care.


In conclusion, the pharmacist’s assertion that the provider cannot administer buprenorphine in the ED without an X-waivered DEA number is inaccurate. The DEA regulations were modified in 2021 to allow physicians with an active DEA registration to provide buprenorphine for acute opioid withdrawal in emergency settings without the need for an X-waiver. This change acknowledges the urgency of treating opioid withdrawal promptly and ensures that patients like the 20-year-old man in the scenario can receive evidence-based care when they need it most. Access to buprenorphine in emergency situations is a crucial step in addressing the opioid epidemic and improving the outcomes of individuals struggling with OUD.
