A provider-focused briefing on Naloxone availability in 2026: shortage timeline, prescribing implications, formulations, cost, and patient access tools.
As a prescriber or healthcare provider, you've likely encountered the downstream effects of Naloxone supply fluctuations — whether it's patients struggling to fill prescriptions, EMS departments rationing injectable vials, or pharmacies reporting inconsistent stock of specific formulations.
This briefing covers the current state of Naloxone availability in 2026, what's changed since the OTC transition, and practical steps you can take to ensure your patients have access to this life-saving medication.
Injectable Naloxone (0.4 mg/mL vials) first appeared on the FDA Drug Shortage list in 2018 as demand surged in response to the escalating opioid epidemic. Hospitals, EMS agencies, and correctional facilities competed for limited supply. During this period, nasal spray (Narcan 4 mg) was available by prescription and through community distribution programs, but access was inconsistent.
In March 2023, the FDA approved Narcan 4 mg nasal spray for over-the-counter sale — a landmark decision. By September 2023, OTC Narcan was on pharmacy shelves nationwide. RiVive (3 mg nasal spray) followed as a second OTC option. Simultaneously, the FDA approved Nalmefene (Opvee), a longer-acting opioid antagonist nasal spray, expanding the reversal agent toolkit.
OTC availability significantly improved community-level access. However, injectable formulations continued to experience intermittent shortages. Rural and underserved areas remained disproportionately affected. The proliferation of illicit Fentanyl — and its increasing potency — drove clinical discussions about whether standard 4 mg nasal doses were sufficient, leading to greater interest in Kloxxado (8 mg) and Zimhi (5 mg IM).
OTC nasal spray supply is broadly stable. Injectable vials remain subject to periodic supply constraints. The market now includes multiple formulations and an alternative agent (Nalmefene), giving providers more options than at any point in the epidemic.
Understanding the prescribing landscape is critical for guiding patients appropriately:
For patients who can access OTC options, a prescription may still be beneficial: it enables insurance billing (often reducing out-of-pocket cost to $0), creates documentation in the medical record, and allows you to specify higher-dose formulations when clinically appropriate.
Consider prescribing Kloxxado (8 mg) or Zimhi (5 mg IM) for patients at higher risk of exposure to synthetic opioids, including:
The CDC and most state guidelines recommend co-prescribing Naloxone with opioid prescriptions, particularly for patients on ≥50 morphine milligram equivalents (MME) per day, patients with concurrent benzodiazepine prescriptions, or patients with a history of substance use disorder. Documenting Naloxone co-prescribing supports quality measures and can be tracked via EHR.
To help patients locate specific products, direct them to Medfinder for Providers, which offers real-time pharmacy stock checking.
Most commercial plans, Medicaid (all 50 states), and Medicare Part D cover prescription Naloxone formulations. Prior authorization is rarely required. Prescribing (rather than directing to OTC) unlocks insurance coverage and may be more cost-effective for patients.
Ensure your patients are aware of free Naloxone programs:
Several developments may further improve Naloxone access in the near future:
Naloxone access in 2026 is better than it has ever been — but gaps persist, particularly for injectable formulations and in underserved communities. As a provider, you play a critical role in ensuring your patients have access by co-prescribing when appropriate, directing them to available formulations, and connecting them with free distribution programs and tools like Medfinder.
