FDA Approves New Over The Counter Opioid Overdose Reversal Spray

The FDA has approved another over-the-counter naloxone nasal spray to reverse an opioid overdose, thereby widening access to a critical emergency tool. But while naloxone saves lives in the moment, addiction specialists stress that medical detox remains the safest next step for anyone ready to start recovery from opioid dependence.

FDA Expands OTC Naloxone Options

The agency approved Rextovy, a 4-mg intranasal naloxone hydrochloride nasal spray, for nonprescription use. It joins other over-the-counter naloxone products on the market since the first nonprescription version was approved in 2023. Individuals can buy the spray at pharmacies, online retailers, and convenience stores without a prescription. It’s also covered by many insurance providers.

“Immediate access to naloxone nasal sprays is essential when a person is experiencing an overdose,” noted Dr. Karen Murry, director of the FDA’s Office of Nonprescription Drug Products. She added that the “FDA remains committed to ensuring nonprescription options are widely available.” The agency also encouraged other manufacturers to seek nonprescription naloxone approvals, noting that more competition among products could help lower costs.

Medical Detox Matters Even with Naloxone Access

Naloxone reverses the immediate, life-threatening effects of an opioid overdose, but it does nothing to treat the underlying dependence that puts a person at risk in the first place. 

That’s where medical detox and ongoing treatment come in. Overdose deaths fell sharply, from roughly 110,000 in 2022 to about 69,000 in 2025, according to the CDC. Experts attribute the decline to several factors working together. These include shifts in the fentanyl supply, broader naloxone availability and expanded access to medication-assisted treatment for opioid use disorders.

That last factor matters most for long-term recovery. Medications such as buprenorphine, methadone and naltrexone often help reduce cravings and withdrawal symptoms while a person stabilizes. Without that kind of support, folks who survive an overdose remain at high risk of returning to opioid use and overdosing again.

Understanding Naloxone

Unlike Suboxone or methadone, naloxone works by rapidly displacing opioids from receptors in the brain, reversing respiratory depression and restoring normal breathing within minutes. The FDA notes you can safely give it even if you don’t know for sure whether opioids caused the overdose. People coming out of an opioid overdose after receiving naloxone may experience shaking, sweating, nausea or anger as withdrawal symptoms set in abruptly. 

Anyone administering the spray should call 911 immediately after the first dose and give additional doses if the person hasn’t woken up within a few minutes.

Levels of Medical Detox Care Explained

Not everyone needs the same level of supervision or detox medications during withdrawal. The American Society of Addiction Medicine (ASAM) outlines several levels of detox care:

• Level 4 (medically-managed intensive inpatient): Hospital-level care for severe, high-risk withdrawal.
• Level 3.7 (medically-monitored inpatient): 24-hour nursing care for moderate to severe withdrawal risk.
• Level 3.2 (clinically-managed residential): Structured support for milder withdrawal under less intensive medical oversight.

A clinician typically determines the right level based on substance use history, prior overdoses and other health conditions.

Medical Detox in the USA

If you or someone you love has survived an opioid overdose, naloxone access is only the first step. Never attempt alcohol or benzodiazepine detox without medical supervision, as withdrawal from those substances can be life-threatening. 

Searching for detox programs or a medical detox center is the safest way to begin opioid recovery under professional supervision, where withdrawal symptoms can be monitored and medication-assisted treatment can be started right away.
