buprenorphine vs cyclobenzaprine
Side-by-side comparison of buprenorphine and cyclobenzaprine. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.
minor Known Drug Interaction
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).
Recommendation: Talk to your doctor about the risks and watch for symptoms like confusion, shivering, or a fast heartbeat.

Buprenorphine sublingual tablets help treat opioid dependence. It should be part of a full treatment plan with counseling and support.
Cyclobenzaprine is a muscle relaxant. It helps relieve muscle spasms and pain.
This medicine treats opioid dependence. Opioid dependence means you feel like you need to take opioids. This medicine can help you manage withdrawal symptoms and reduce cravings.
This medicine treats muscle spasms caused by painful conditions. It is meant to be used with rest and physical therapy. It should only be used for a short time, usually 2 to 3 weeks.
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.
Cyclobenzaprine works in the brain and spinal cord to relax your muscles. It reduces muscle spasms, which helps to relieve pain and improve movement. It does not directly work on the muscles themselves.

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.
You should not take this medicine if you are allergic to any of its ingredients. You should not take this medicine if you are taking a monoamine oxidase (MAO) inhibitor or have taken one in the past 14 days. Taking cyclobenzaprine with an MAO inhibitor can cause serious problems, including seizures and death. Also, do not take it if you have heart problems or an overactive thyroid.
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.
It is not known if cyclobenzaprine can harm an unborn baby. Talk to your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How to Read This buprenorphine vs cyclobenzaprine Comparison
buprenorphine is classified in the Partial Opioid Agonist drug class, while cyclobenzaprine sits within the Muscle Relaxant class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, buprenorphine has 55,521 submissions while cyclobenzaprine has 18,026. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to both drugs increase serotonin levels in the brain, which can cause a serious and potentially dangerous reaction.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
