It should only be used for short periods of time, usually 2-3 weeks FLEXERIL 5 mg is a prescription medicine and should not be taken by patients who have had a recent heart attack or have heart disease. It should not be used by people with an overactive thyroid or who are currently or have recently used MAOIs. Use of FLEXERIL 5 mg with MAOIs can result in serious health complications. Cyclobenzaprine can increase the effects of CNS depressants, such as alcohol, opioids, allergy medications, and sleeping pills.

In preclinical research, cyclobenzaprine reduced skeletal muscle hyperactivity. Research indicates that it primarily acts within the central nervous system in the brain stem. Our goal is to provide you with the most relevant and current information. However, because drugs affect each person differently, we cannot guarantee that this information includes all possible side effects. This information is not a substitute for medical advice.

Conditions

Studies have compared cyclobenzaprine, methocarbamol, and other skeletal muscle relaxants and found that they are equally effective in treating acute musculoskeletal conditions. Cyclobenzaprine is one of the most studied skeletal muscle relaxants, with solid evidence and systematic reviews supporting its effectiveness. This may place them at an increased risk of encountering side effects such as drowsiness and fatigue from too much medication, according to the study’s primary investigator.

  • This is especially true if someone has been engaging in polydrug use with cyclobenzaprine and other substances.
  • Robaxin is the brand name of the generic medication called methocarbamol.
  • Cyclobenzaprine is the generic version of Flexeril, and requires a prescription.
  • Flexeril (generic name cyclobenzaprine) was developed in the 1970s.
  • Monitoring of plasma drug levels should not guide management of the patient.
  • These patients are generally more susceptible to drugs with potentially sedating effects, including cyclobenzaprine.

Although rare, deaths may occur from overdosage with FLEXERIL. Multiple drug ingestion (including alcohol) is common in deliberate cyclobenzaprine overdose. As management of overdose is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. Signs and symptoms of toxicity may develop rapidly after cyclobenzaprine overdose; therefore, hospital monitoring is required as soon as possible. The acute oral LD50 of FLEXERIL is approximately 338 and 425 mg/kg in mice and rats, respectively. The plasma concentration of cyclobenzaprine is increased in the elderly (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Elderly).

As discussed above, the clinician should consider contacting the poison control center in refractory cases. A psychiatrist consult is required for deliberate poisoning of cyclobenzaprine. Clinicians should monitor for signs and symptoms of serotonin syndrome if the patient is taking other serotonergic drugs. In two case reports, the authors described patients who quickly developed serotonin syndrome after initiating cyclobenzaprine in the short term. In both cases, the patients took serotonergic medications (phenelzine and duloxetine) before starting cyclobenzaprine.[21] Clinicians should also monitor for vital signs, as cyclobenzaprine can cause reflex tachycardia.

In the US – Call your doctor for medical advice about side effects. You may report side effects to FDA at FDA-1088 or at /medwatch. If any of these effects last or get worse, tell your doctor or pharmacist promptly. Overdose symptoms may include severe drowsiness, vomiting, fast heartbeats, tremors, agitation, or hallucinations. You should discuss the treatment options with your doctor.

Other drugs may affect cyclobenzaprine, including prescription and over-the-counter medicines, vitamins, and herbal products. Cyclobenzaprine comes as a tablet and an extended-release capsule to take by mouth. The tablet is usually taken with or without food three times a day. The extended-release capsule is usually taken with or without food once a day. Do not take this drug for more than 3 weeks without talking to your doctor.

Cyclobenzaprine belongs to a class of drugs called muscle relaxants. A class of drugs is a group of medications that work in a similar way. Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Do not take this drug again if you’ve ever had an allergic reaction to it. Professionals generally consider Flexeril to be nonaddictive; however, there is evidence that Flexeril addiction is possible. Flexeril depresses the central nervous system, an effect some find desirable, which can lead to misuse. An individual flexeril allergy might abuse Flexeril in order to feel relaxed, mildly euphoric, or sedated. Flexeril produces a variety of anticholinergic effects in high doses, altering the activity of brain neurotransmitters. Additionally, Flexeril users may experience mild withdrawal symptoms if the drug is used chronically in high doses.
