What it does
This medicine treats opioid dependence.
Common side effects
Headache, Nausea, Vomiting
Key warnings
Buprenorphine can be abused, like other opioids.
The sections below are summarized in plain English from buprenorphine's FDA-approved prescribing information. They describe what the official label says, and are not personal medical advice.
How It Works
Buprenorphine is a partial opioid agonist. This means it binds to the same receptors in the brain as opioids, but it does not activate them as strongly. This helps to reduce cravings and withdrawal symptoms without causing the same high as other opioids.
Side Effects (from patient reports)

Where buprenorphine sits
buprenorphine has more FDA adverse-event reports than 84% of the drugs FAERS tracks. A high position reflects how widely a drug is used and watched, not how dangerous it is.

Serious Warnings
Buprenorphine can be abused, like other opioids. Taking buprenorphine with benzodiazepines or other depressants can cause serious breathing problems, coma, or death. Keep this medicine out of the reach of children, as it can cause severe breathing problems and death. Using opioids for a long time during pregnancy can cause withdrawal symptoms in the newborn.
Known Drug Interactions
Intervention: Avoid concomitant use Examples: Butorphanol, nalbuphine, pentazocine, buprenorphine Muscle Relaxants Clinical Impact: Oxycodone may enhance the neuromuscular blocking action of skeletal muscle relaxants and produce an increased degree of respiratory depression.
Mechanism: Oxycodone can make the muscle-weakening effects of other drugs stronger and can cause your breathing to slow down significantly. This combination can be very dangerous for your lungs and muscles.
Examples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), certain muscle relaxants (i.e., cyclobenzaprine, metaxalone), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).
Mechanism: Both of these medications increase the amount of a brain chemical called serotonin. Taking them at the same time can cause serotonin levels to become dangerously high.
Examples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), certain muscle relaxants (i.e., cyclobenzaprine, metaxalone), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).
Mechanism: Both drugs increase serotonin levels in the brain, which can cause a serious and potentially dangerous reaction.
Examples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), certain muscle relaxants (i.e., cyclobenzaprine, metaxalone), monoamine oxidase (MAO) inhibitors (those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).
Mechanism: These medications both affect the serotonin system, and taking them together can lead to a dangerous buildup of this chemical in your body.
ketoconazole), protease inhibitors (e.g., ritonavir) CYP3A4 Inducers Clinical Impact: The concomitant use of buprenorphine and CYP3A4 inducers can decrease the plasma concentration of buprenorphine [see Clinical Pharmacology (12.3)] , potentially resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to buprenorphine.
Mechanism: Ketoconazole interferes with the enzymes that break down buprenorphine, which can change the amount of medicine that stays in your blood.

What the FDA Data Shows for buprenorphine
The FDA label for buprenorphine (sold under brand names such as Subutex, Sublocade) classifies it as a prescription-only medication in the Partial Opioid Agonist class. This medicine treats opioid dependence. Official labeling lists 11 commonly reported side effects, including Headache, Nausea, Vomiting.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 90,121 voluntary reports. The database also lists 29 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated moderate severity. NADAC pricing from CMS shows a generic unit cost of $28.84.
Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history (currently 1 recall record on file), and patent information are separate source-record fields. This page is a public FDA/CMS registry and does not provide medical, treatment, substitution, or medication-change directions.
