Individuals facing opioid addiction have several medication options available to support both their short- and long-term recovery. Selecting buprenorphine vs methadone depends on factors such as the severity of the addiction, treatment settings, personal preferences, available support systems and the individual’s commitment to maintaining sobriety.
What Is Buprenorphine?
Buprenorphine is a widely used FDA-approved medication for opioid addiction. It is a partial opioid agonist used to improve cravings, offering comfort and support during the withdrawal period and long-term sobriety.
How It Works
Buprenorphine works by binding to and partially activating the brain’s mu-receptors. Because it causes only partial activation, cravings and withdrawal symptoms are eased without producing a strong high.
Buprenorphine has a strong safety profile because it has a “ceiling effect.” This “ceiling effect” limits the risk of central nervous system depression and overdose, even when taken at moderate doses. Increasing the dose does not produce a stronger high.
Furthermore, because it stays in the body for a long time, it only needs to be taken once per day, helping to keep a consistent level of the medication in the bloodstream.
Suboxone vs Subutex
Suboxone and Subutex are used to treat opioid dependence and manage opiate withdrawal symptoms.
Yet, some key differences exist and should be considered:
- Suboxone contains buprenorphine and naloxone, thereby decreasing abuse potential.
- Subutex is the preferred choice for those who are pregnant.
- Subutex is often used to begin treatment, while Suboxone is used as a long-term support medication.
- Suboxone can be taken as a sublingual tablet or film, but Subutex is only offered in pill form.
- The brand name “Subutex” was discontinued in 2011, with the medication remaining available under its generic name buprenorphine.
Risk of overdose with Suboxone and continuing drug use should be considered, and Suboxone should not be used if complete sobriety is unattainable.
What Is Methadone?
Methadone is another medication that is used to treat opioid addiction. Methadone is a long-acting medication, thereby helping during the withdrawal period and aiding long-term recovery.
Full Opioid Agonist
Methadone completely binds to the mu-opioid receptors in the brain, pushing them to their full capacity.
Methadone effectiveness stems from:
- Reducing pain
- Creating a sense of calm
- Inhibiting the body’s ability to tolerate other opioids
Clinic-Only Treatment
Unlike buprenorphine, which can be taken at home, methadone is restricted to use within an addiction treatment facility or methadone clinic.
Key Differences Between Buprenorphine vs Methadone
Both buprenorphine and methadone are used in Medication-assisted treatment. While both are effective, it is best to understand where they are the same and where they differ before choosing which option will meet your needs.
Safety
Buprenorphine can be considered safer than methadone, due to its ceiling effect that limits the potential for fatal overdose and respiratory distress.
Furthermore, buprenorphine is considered a safer option during pregnancy as it has been shown to reduce the risk of neonatal abstinence syndrome.
Overdose Risk
Although both medications have longer half-lives than short-acting opioids like heroin or morphine, due to methadone’s long half-life, methadone carries a six times greater risk of overdose.
Access
Buprenorphine is easier to access than methadone, as buprenorphine can be taken at home, while methadone remains a clinic-based treatment, to best ensure the safety of the recipient.
Side Effects
Methadone and buprenorphine share similar side effects: constipation, headache, nausea, dizziness, and insomnia.
Methadone carries the risk of possible heart problems, including QT interval prolongation and buprenorphine has the potential to affect liver functioning.
Withdrawal Severity
Withdrawal symptoms are possible when methadone and buprenorphine are stopped. The severity of withdrawal symptoms depends on the dosage and duration of the medication use.
Methadone withdrawal can include anxiety, insomnia, agitation, flu-like symptoms and possibly psychosis.
Buprenorphine withdrawal can cause anxiety, bone pain, muscle aches, tearfulness and restlessness, but these have been reported as low to moderate in severity.
Which Is More Effective?
Methadone vs. Suboxone are both great options, but methadone is considered more effective and has higher treatment retention rates.
Methadone use does carry the risk of overdose and requires clinical management. Choosing between methadone and buprenorphine largely depends on the severity of addiction, patient stability and recovery care needs.
Who Should Choose Buprenorphine?
Buprenorphine is an ideal option for individuals who have a mild to moderate addiction and need less direct care management with flexibility, as well as those who are deeply committed to sobriety.
Who Should Choose Methadone?
Methadone is the best option for individuals who have severe and long-term opioid addiction, have failed treatment with buprenorphine, and need structured support of supervised administration.
Furthermore, methadone is a safer option for pregnant women because it helps to prevent withdrawal symptoms that can trigger preterm birth or miscarriage.
Buprenorphine vs Methadone FAQs
Is Methadone Stronger than Buprenorphine?
Methadone is considered the stronger medication, as it works as a full opioid agonist. Buprenorphine is a partial opioid agonist that produces a “ceiling effect,” which reduces the risk of overdose.
Can You Switch from Methadone to Suboxone?
Switching from methadone to Suboxone is possible with proper titration. Methadone should not be stopped suddenly to avoid severe withdrawal symptoms.
Those switching from methadone to Suboxone are given a lower dose of methadone until withdrawal symptoms develop, and then placed on Suboxone, with a gradual increase of dosage as needed.
Which Medication Has Fewer Side Effects?
Generally speaking, buprenorphine has fewer side effects than methadone, stemming from its ceiling effect, making dependence, overdose and respiratory depression less likely.
Can You Overdose on Buprenorphine?
Overdosing on buprenorphine is possible, but highly unlikely when the medication is taken as prescribed, and without the use of opioids or other substances.
How Long Do You Stay on Methadone?
Methadone treatment can be used short-term, but better outcomes are shown after a year or more of medication. Methadone can become a lifelong treatment option.
