Can't find Buprenorphine/Naloxone? Learn about alternatives like Methadone, Naltrexone, Sublocade, and Brixadi for opioid use disorder treatment.
Being unable to find your Buprenorphine/Naloxone prescription is more than an inconvenience — it can feel like a threat to your recovery. Whether your pharmacy is out of stock, your insurance won't cover it, or you're facing other access barriers, the most important thing is that you don't go without treatment.
The good news is that Buprenorphine/Naloxone isn't the only medication approved to treat opioid use disorder (OUD). There are several evidence-based alternatives, each with its own benefits and considerations. This guide will help you understand your options so you can have an informed conversation with your provider.
Buprenorphine/Naloxone — sold under brand names like Suboxone, Zubsolv, and Bunavail — is a combination medication used to treat opioid use disorder. It's classified as a Schedule III controlled substance.
Buprenorphine is a partial opioid agonist. This means it activates the same brain receptors as opioids like Heroin or Fentanyl, but only partially. It's enough to reduce cravings and prevent withdrawal symptoms, but it doesn't produce the same intense high. It also has a "ceiling effect" — after a certain dose, taking more doesn't increase its effects, which makes overdose less likely.
Naloxone is an opioid antagonist added to discourage misuse. When taken under the tongue as directed, Naloxone has minimal effect because it's poorly absorbed that way. But if someone tries to inject the medication, the Naloxone activates and blocks opioid receptors, causing withdrawal symptoms.

Methadone is a full opioid agonist that has been used to treat opioid addiction since the 1960s. It's one of the most well-studied medications for OUD and is equally effective as Buprenorphine in reducing opioid use.
How it works: Methadone fully activates opioid receptors, eliminating withdrawal symptoms and cravings. Because it's long-acting, it's taken once daily.
Key differences from Buprenorphine/Naloxone:
Best for: Patients who haven't responded well to Buprenorphine/Naloxone, those with severe OUD, or patients who benefit from the structured environment of a clinic.
Naltrexone is an opioid antagonist — it works by completely blocking opioid receptors in the brain. The extended-release injectable form, sold as Vivitrol, is given as a monthly shot.
How it works: Instead of partially activating opioid receptors like Buprenorphine, Naltrexone blocks them entirely. This means opioids have no effect if you use them while on Naltrexone. It also reduces cravings over time.
Key differences from Buprenorphine/Naloxone:
Best for: Patients who have completed detox, those who prefer a non-opioid treatment, or patients who want a monthly injection rather than daily medication.
Sublocade is a monthly injection of Buprenorphine that forms a solid deposit under the skin, slowly releasing medication over 30 days. It eliminates the need for daily sublingual dosing.
How it works: It delivers the same active ingredient as Buprenorphine/Naloxone (without the Naloxone component) through a once-monthly injection given by a healthcare provider.
Key differences from Buprenorphine/Naloxone:
Best for: Patients who are stable on Buprenorphine but want the convenience of monthly dosing, or those who struggle with medication adherence.
Brixadi is a newer option approved by the FDA in 2023. Like Sublocade, it's an extended-release Buprenorphine injection, but it comes in both weekly and monthly formulations.
How it works: Brixadi delivers Buprenorphine subcutaneously, providing steady medication levels without daily dosing.
Key differences from Buprenorphine/Naloxone:
Best for: Patients who want flexible injection scheduling or those just starting Buprenorphine treatment who prefer not to take daily sublingual medication.
Choosing the right OUD medication depends on several factors:
Talk to your prescriber about which option makes the most sense for your situation. You can also find a provider who prescribes medications for OUD near you.
Not being able to fill your Buprenorphine/Naloxone prescription is stressful, but it doesn't mean you're out of options. Methadone, Naltrexone (Vivitrol), Sublocade, and Brixadi are all FDA-approved alternatives that can help you stay in recovery.
