What it does
This medicine treats opioid dependence.
Common side effects
Headache, Nausea, Vomiting
Key warnings
Buprenorphine can be abused, like other opioids.
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.
How to Take It
Take buprenorphine sublingual tablets under your tongue once a day. Do not cut, chew, or swallow the tablet. Let it dissolve completely under your tongue. When stopping treatment, your doctor will slowly lower your dose to prevent withdrawal symptoms.
Pregnancy & Breastfeeding
If you are pregnant or plan to become pregnant, talk to your doctor. Using this medicine during pregnancy can cause withdrawal symptoms in your baby after birth. Buprenorphine can pass into breast milk.
Missed Dose
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take your next dose at the regular time.
Storage
Store buprenorphine sublingual tablets at room temperature (68° to 77°F) and protect them from light.
Side Effects (from patient reports)

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.
What to do: You should avoid using these two medications together to prevent serious breathing or muscle problems.
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.
What to do: Watch for signs like confusion, fast heartbeat, or shivering, and seek medical help if they occur.
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.
What to do: Talk to your doctor about the risks and watch for symptoms like confusion, shivering, or a fast heartbeat.
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.
What to do: Your healthcare provider should monitor you closely for signs of serotonin syndrome if these drugs are used together.
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 to do: Your doctor may need to adjust your dose and monitor you for increased side effects or signs of withdrawal.

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 82,069 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, and patent information further shape supply and switching decisions.
