Understanding the Goals of Medication-Assisted Treatment (MAT)
Medication-Assisted Treatment (MAT) is the gold standard for treating opioid use disorder (OUD) and is recommended for all individuals with OUD, regardless of severity. MAT combines FDA-approved medications with counseling and behavioral therapies to provide a whole-person approach to recovery. The medications help normalize brain chemistry, relieve cravings, and block the euphoric effects of opioids, making it easier for individuals to focus on therapy and rebuild their lives. Suboxone, which contains buprenorphine and naloxone, is a common and highly effective MAT option, but it is not the only choice. When Suboxone is not the right fit, for reasons including side effects, personal preference, or specific clinical needs, several other alternatives are available and effective.
Alternatives to Suboxone: Other Buprenorphine Products
Suboxone is a combination product of buprenorphine and naloxone, but other formulations containing buprenorphine are available. These options provide similar benefits for reducing withdrawal symptoms and cravings but with different administration methods or formulations.
Sublocade (buprenorphine extended-release injection)
Sublocade is a long-acting, injectable form of buprenorphine that provides a constant, therapeutic level of medication over a month. This is an excellent option for patients who prefer the convenience of a single monthly dose over daily medication and for those who may have adherence issues with daily oral strips or tablets. A healthcare provider must administer the injection, which reduces the potential for misuse or diversion. However, patients must first be stabilized on an oral buprenorphine product for at least seven days before starting Sublocade.
Zubsolv (buprenorphine and naloxone sublingual tablets)
Zubsolv is another combination product containing buprenorphine and naloxone, similar to Suboxone, but it is a tablet dissolved under the tongue rather than a film strip. Some patients may find the taste or texture of Zubsolv more tolerable than Suboxone film. It has comparable efficacy to Suboxone in managing withdrawal and cravings but is often more expensive.
Generic Buprenorphine (pure buprenorphine products)
Generic buprenorphine, sometimes referred to as Subutex (the brand name was discontinued), contains only buprenorphine without naloxone. This may be a suitable alternative for individuals who cannot tolerate naloxone, a rare occurrence. Pregnant women, in some cases, may also be prescribed pure buprenorphine. However, without the naloxone deterrent, these products have a slightly higher risk for misuse compared to Suboxone.
Alternatives to Suboxone: Non-Buprenorphine Options
For individuals who prefer not to use an opioid agonist medication or who have specific treatment needs, non-buprenorphine alternatives are also FDA-approved and highly effective.
Methadone
Methadone is a long-acting, full opioid agonist that has been used for decades to treat OUD. It is highly effective at reducing cravings and withdrawal symptoms and is associated with reduced overdose deaths. Because it is a full agonist, it has a higher potential for misuse than buprenorphine and is therefore more tightly regulated. Patients typically must visit a certified Opioid Treatment Program (OTP) daily to receive their dose, although take-home doses may be permitted over time.
Naltrexone (Vivitrol)
Unlike methadone and buprenorphine, naltrexone is a pure opioid antagonist that blocks opioid receptors, preventing the euphoric effects of other opioids. Naltrexone is non-addictive and does not cause physical dependence. It is available as a daily oral tablet (ReVia) or, more commonly for OUD, as a once-monthly extended-release injection (Vivitrol). A significant requirement for starting naltrexone is that the patient must be opioid-free for at least 7 to 10 days to avoid precipitating immediate and severe withdrawal. This can make starting naltrexone more difficult for some people.
Lofexidine (Lucemyra)
Lofexidine is a non-opioid medication approved to manage the acute symptoms of opioid withdrawal during detoxification. It does not treat the underlying OUD but can make the detox process more tolerable by easing symptoms like stomach cramps, muscle spasms, and sleeplessness. It is often used to help patients manage withdrawal symptoms for up to 14 days, particularly those transitioning to naltrexone.
Comparison Table: Suboxone vs. Other OUD Medications
| Feature | Suboxone (Buprenorphine/Naloxone) | Methadone | Naltrexone (Vivitrol) |
|---|---|---|---|
| Mechanism | Partial opioid agonist + antagonist deterrent | Full opioid agonist | Pure opioid antagonist (blocks receptors) |
| Formulation | Sublingual film or tablet | Oral liquid, pill, or diskettes | Once-monthly injection (Vivitrol) or oral daily pill (ReVia) |
| Dependence | Partial opioid dependence; gradual taper required | Full opioid dependence; requires supervised taper | Non-addictive; no dependence |
| Administration | Daily at home | Daily at licensed clinic (can earn take-homes) | Monthly injection at doctor's office |
| Misuse Potential | Low; naloxone prevents misuse if injected | High; tightly regulated | None; blocks opioid effects |
| Overdose Risk | Low risk due to 'ceiling effect' | Higher risk if not used as prescribed | No risk from naltrexone, but risk if patient relapses after abstinence |
| Starting Treatment | Requires moderate withdrawal before induction | Can start during active opioid use | Must be opioid-free for 7-10 days |
Making an Informed Choice with a Healthcare Provider
The decision of what is a good substitute for Suboxone is not one to make alone. It requires a collaborative discussion with a healthcare provider who specializes in addiction medicine. The best medication is a highly individualized decision, taking into account several factors:
- Severity and history of OUD: For long-term or severe OUD, methadone may be necessary to manage cravings effectively.
- Lifestyle and preferences: Patients who struggle with daily medication adherence may benefit from a monthly injection like Sublocade or Vivitrol.
- Tolerance and side effects: If a patient is sensitive or intolerant to a component of Suboxone, like naloxone, a different formulation or medication is warranted.
- Access to care: Methadone requires regular visits to a specialized clinic, which can be a barrier for some. In contrast, buprenorphine and naltrexone can be prescribed in office-based settings.
- Treatment goals: Some individuals may prefer a non-opioid option like Vivitrol, while others need the agonist effects of buprenorphine or methadone to prevent withdrawal and cravings.
Conclusion
While Suboxone is a foundational medication for treating opioid use disorder, many effective alternatives exist to accommodate different patient needs and preferences. Whether it's another form of buprenorphine like Sublocade, a full agonist like methadone, or an antagonist like naltrexone, all are proven to reduce opioid use and improve outcomes when combined with a comprehensive treatment program. Open and honest communication with a healthcare professional is the most important step in determining the ideal medication and treatment plan for sustained recovery.
