Cyclobenzaprine, also known by the brand names Flexeril (now discontinued) and Amrix, is a skeletal muscle relaxant. Its primary medicinal use is for pain, tenderness and limitation of motion associated with muscle spasms.
Cyclobenzaprine is available in several different forms, including tablet (5 mg, 7.5 mg, or 10 mg doses) and extended release capsule form (in 15 mg or 30 mg doses).1,2
Physical therapy and rest are generally recommended with cyclobenzaprine treatment, and treatment with this medication is designed to be short-term (up to 2 to 3 weeks).1 While rare, it is possible for someone ending their cyclobenzaprine use to experience certain muscle relaxer withdrawal symptoms.3
Someone quitting cyclobenzaprine might experience mild discomfort that is similar to the withdrawal symptoms that occur in individuals who use tricyclic antidepressants. Cyclobenzaprine withdrawal symptoms may include:3
If you are only taking cyclobenzaprine, withdrawal is not likely to be serious. Your physician can help you taper off the drug to avoid unpleasant symptoms of withdrawal. If you are physically dependent on one or more other drugs, however, muscle relaxer withdrawal may be uncomfortable or complicated.4
Is Flexeril addictive? Cyclobenzaprine is not a controlled substance in the United States; however, it does appear to have some potential for abuse.2
According to 2017 data from the Substance Abuse and Mental Health Services Administration, an estimated 250,000 million people misused muscle relaxants in 2016.5 Also, per the Drug Enforcement Administration, internet activity suggests that people are intentionally misusing cyclobenzaprine with other drugs for a high, and emergency room visits involving the drug more than doubled between 2004 and 2010.2
It is especially risky to abuse cyclobenzaprine with other drugs that depress the central nervous system, such as:
Cyclobenzaprine may intensify the effects of the drugs above and the individual may suffer an overdose. In cases of deliberate overdose, ingestion of multiple drugs is common.6 Overdose may result in extremely serious problems including seizures, cardiac arrest, neuroleptic malignant syndrome, and death.3
The scope of cyclobenzaprine misuse and abuse appears to be very small in comparison with other drugs like opioids, benzodiazepines, or alcohol.5 However, some people may add cyclobenzaprine to the mix while abusing their main drug of choice.
Misusing cyclobenzaprine may be indicative of a larger problem with substance abuse. Signs of a problem with substance abuse include:7
If you are struggling with substance abuse, including abuse of cyclobenzaprine, don’t wait to get treatment. Combining it with other drugs to get a better high could lead you to experience a potentially fatal overdose.3
