In 2022, an estimated 9.3 million adults in the U.S. needed treatment for Opioid Use Disorder (OUD), yet only about 25% received medications for it [1.8.2]. This article explores a key one of those medications, answering: What is the medication buprenorphine used for?

Quick Summary

Buprenorphine is a medication primarily used for treating opioid use disorder and managing chronic pain. It helps reduce cravings and withdrawal symptoms, acting as a partial opioid agonist with a lower risk of misuse than full agonists.

Key Points

Primary Uses: Buprenorphine is mainly used to treat Opioid Use Disorder (OUD) and to manage severe or chronic pain [1.2.5].
Mechanism: It is a partial opioid agonist that reduces cravings and withdrawal without the full effect of opioids like heroin or methadone [1.2.1].
Safety Profile: It has a "ceiling effect," which lowers the risk of respiratory depression and overdose compared to full opioid agonists [1.2.2].
OUD Treatment: For OUD, it's often combined with naloxone (e.g., Suboxone) to deter misuse and can be prescribed in office-based settings [1.2.2, 1.3.1].
Pain Management: For chronic pain, it's available as a long-acting transdermal patch (Butrans®) or a buccal film (Belbuca®) [1.10.1].
Accessibility: Unlike methadone, which requires visits to a specialized clinic, buprenorphine can be prescribed by qualified providers and taken at home [1.3.1].
Initiating Treatment: For OUD, treatment must start when the patient is in mild to moderate withdrawal to avoid precipitating a more severe withdrawal [1.2.1].

Introduction to Buprenorphine

Buprenorphine is a synthetic opioid medication developed in the late 1960s and approved by the FDA for two primary purposes: treating Opioid Use Disorder (OUD) and managing severe or chronic pain [1.4.5, 1.2.5]. As a Schedule III drug, it has a lower to moderate potential for physical dependence compared to Schedule II opioids like oxycodone and fentanyl [1.4.4, 1.2.5]. It's the first OUD medication that can be prescribed in physician offices, which significantly increases access to care [1.2.1]. Treatment with buprenorphine is most effective when part of a comprehensive plan that includes counseling and behavioral therapies [1.2.2].

How Buprenorphine Works: The Pharmacology

Buprenorphine is classified as a partial opioid agonist [1.2.1]. This means it binds to and activates the brain's mu-opioid receptors, but to a lesser degree than full agonists like heroin or methadone [1.5.2, 1.2.2]. This unique mechanism provides several key benefits:

Reduces Cravings and Withdrawal: By partially activating opioid receptors, it diminishes the physical dependency effects, such as cravings and painful withdrawal symptoms [1.2.1].
Blocks Other Opioids: Buprenorphine has a high affinity for mu-opioid receptors, meaning it binds to them tightly. This can block other opioids from attaching to the receptors, preventing them from producing a “high” [1.5.3].
Ceiling Effect: Its opioid effects level off at moderate doses, even with further increases. This “ceiling effect” lowers the risk of respiratory depression, misuse, and fatal overdose compared to full agonists [1.2.2, 1.4.4].

Primary Uses of Buprenorphine

Buprenorphine has two main FDA-approved indications: Opioid Use Disorder and pain management [1.2.5].

Treating Opioid Use Disorder (OUD)

Buprenorphine is a gold-standard, first-line treatment for OUD [1.3.4, 1.3.2]. It helps people reduce or stop their use of other opioids by controlling withdrawal symptoms and cravings, allowing them to focus on recovery [1.3.1]. Treatment typically begins when a person is in the early stages of withdrawal, usually 12 to 24 hours after their last use of a short-acting opioid [1.2.1]. Starting it too early, while other opioids are still in the bloodstream, can cause precipitated withdrawal, which is an abrupt and intense onset of withdrawal symptoms [1.11.3, 1.2.2].

Many buprenorphine products for OUD are combined with naloxone (e.g., Suboxone, Zubsolv) [1.2.2]. Naloxone is an opioid antagonist that is poorly absorbed when taken sublingually as directed. However, if the product is misused by injecting it, the naloxone becomes active and can induce withdrawal symptoms, which deters misuse [1.5.3, 1.4.5].

Managing Chronic Pain

Buprenorphine is also an effective analgesic for severe chronic pain that requires around-the-clock, long-term opioid treatment [1.4.4]. Its unique pharmacology makes it a safer alternative to traditional Schedule II opioids for some patients, especially the elderly or those with renal impairment [1.4.4]. Various formulations are available for pain management:

Buccal Film (Belbuca®): Applied to the inside of the cheek every 12 hours [1.10.1].
Transdermal Patch (Butrans®): A patch worn on the skin and changed every seven days, providing a continuous low dose [1.4.4, 1.10.1].

These formulations offer high bioavailability while bypassing the digestive system, and they are associated with a lower risk of side effects like constipation compared to full opioid agonists [1.4.4, 1.10.1].

Comparison of Buprenorphine vs. Methadone

Both buprenorphine and methadone are effective medications for OUD, but they have key differences. Methadone is a full opioid agonist and can only be dispensed through federally certified opioid treatment programs (OTPs) [1.2.1, 1.7.4]. Buprenorphine, a partial agonist, can be prescribed by qualified practitioners in an office setting, making it more accessible [1.3.1].


Feature	Buprenorphine	Methadone
Mechanism	Partial opioid agonist [1.2.1]	Full opioid agonist [1.7.3]
Overdose Risk	Lower, due to "ceiling effect" on respiratory depression [1.7.3]	Higher, especially when combined with other substances [1.7.4]
Accessibility	Can be prescribed in an office setting and taken at home [1.3.1]	Generally dispensed daily at a specialized clinic (OTP) [1.7.4]
Treatment Retention	Studies show slightly lower retention rates than methadone [1.7.1, 1.7.3]	Higher treatment retention rates in many studies [1.7.1, 1.7.4]
Side Effects	Less sedation, but can cause headache, nausea, constipation [1.6.1, 1.6.2]	More sedation, constipation, and risk of cardiac issues (QT prolongation) [1.7.1, 1.7.4]
Best For	Patients with social stability, lower tolerance, or risk of methadone toxicity [1.7.4]	Patients with higher tolerance, at risk of treatment dropout, or who did not respond to buprenorphine [1.7.4]

Common Formulations

Buprenorphine comes in several forms tailored for either OUD or pain management [1.10.1].

For OUD:
- Sublingual Films/Tablets (Suboxone®, Zubsolv®): A combination of buprenorphine and naloxone that dissolves under the tongue [1.10.3, 1.2.2].
- Sublingual Tablets (Subutex®): Buprenorphine-only tablets, often used for treatment induction or in pregnancy [1.10.1, 1.3.4].
- Monthly Injection (Sublocade®): An extended-release injection given by a healthcare provider after a patient is stable on a sublingual form [1.10.1, 1.3.4].
For Chronic Pain:
- Buccal Film (Belbuca®): A film that adheres to the inside of the cheek [1.10.1].
- Transdermal Patch (Butrans®): A 7-day patch applied to the skin [1.10.1].

Frequently Asked Questions

No. Buprenorphine is a medication prescribed by a clinician as part of a comprehensive treatment plan that often includes counseling [1.2.1, 1.9.3]. It does not produce the same euphoric high as illicit opioids and helps manage withdrawal and cravings, enabling individuals to focus on recovery and improving social functioning [1.9.3, 1.2.2].

Buprenorphine is the active medication. Suboxone is a brand name for a product that combines buprenorphine with naloxone [1.3.1]. The naloxone is added to deter misuse; it is not active when taken as directed under the tongue but will cause withdrawal symptoms if injected [1.5.3].

While buprenorphine has a ceiling effect on respiratory depression, making overdose less likely than with full agonists, it is still possible, especially if mixed with other central nervous system depressants like alcohol or benzodiazepines [1.6.1, 1.5.5]. Nearly all buprenorphine-involved overdose deaths involve at least one other drug [1.8.1].

The duration of buprenorphine treatment is tailored to the individual and can be indefinite [1.2.1]. The American Society of Addiction Medicine (ASAM) does not recommend a specific time limit, and longer treatment durations are generally associated with more positive long-term outcomes [1.2.5].

Common side effects include constipation, headache, nausea, vomiting, drowsiness, and sweating [1.6.1]. More serious side effects can include respiratory distress, dependence, and potential dental problems with oral formulations [1.6.1, 1.6.2].

Yes, buprenorphine is considered a safe and effective treatment for opioid use disorder during pregnancy [1.3.3]. Treatment with buprenorphine during pregnancy may lead to better health outcomes for the infant compared to methadone, including less severe neonatal opioid withdrawal syndrome [1.3.3].

No. As of 2023, the federal X-waiver requirement for prescribing buprenorphine for opioid use disorder was eliminated. Any clinician with a standard DEA registration that includes Schedule III authority can now prescribe it, if permitted by state law [1.2.5, 1.9.3].
