Mail-Back Envelope Program availability
Covered when ALL of the following are met
Each envelope includes instructions and a Patient Education Sheet (English and Spanish).
The OA REMS modification makes prepaid mail-back envelopes available to pharmacies, but does not require pharmacies to use them. Pharmacies may choose to provide envelopes to patients and caregivers or may continue to offer alternative disposal options (for example, on-site collection bins) according to their policies and local regulations. This policy does not create a mandatory obligation for dispensers to distribute mail-back envelopes.
Pharmacy and Provider Actions
Ordering envelopes — no prior authorization required
Pharmacies may order prepaid drug mail-back envelopes at no charge from the Safe Opioid Disposal Materials page on the OA REMS website or by calling 1-800-503-0784. No prior authorization is required for pharmacies to obtain these envelopes.
Step therapy — not applicable
Step therapy does not apply to disposal materials; the REMS modification does not impose any step therapy requirements for mail-back envelopes.

How Patients Use the Mail-Back Envelopes

Key Definitions
Background and Rationale
Unused opioid analgesics in the home increase the risk of accidental exposure and overdose among household members who were not prescribed the medication, including children, and are a common source for nonmedical opioid use. To reduce these risks, the OA REMS was modified to expand availability of safe disposal by providing pharmacies access to prepaid mail-back envelopes they can distribute to patients and caregivers.
Policy Revision History
Pharmacies can order opioid mail-back envelopes free of charge through the Mail-Back Envelope Program and distribute them to patients for safe opioid disposal, operationalizing the REMS modification requiring manufacturers to provide prepaid envelopes to dispensers upon request.
