Drugs Products
  • Fexmid (cyclobenzaprine)
FDA-Approved Indications:
  • Adjunct to rest and physical therapy for relief of muscle spasm associated with acute, painful musculoskeletal conditions


Background:
  • Fexmid relieves muscle spasms through a central action, possibly at the brain stem level, with no direct action on the neuromuscular junction or the muscle involved.
  • Cyclobenzaprine tablets are available in 5 mg, 7.5 mg, and 10 mg strengths. The 5 mg and 10 mg tablets are generics of Flexeril while the 7.5 mg tablets are generics of Fexmid.
  • For most patients, the recommended dose of cyclobenzaprine is 5 mg three times a day. Based on individual patient response, the dose may be increased to 10 mg three times a day.
  • Muscle relaxants should only be used for short periods (up to two or three weeks) because adequate evidence of effectiveness for more prolonged use is not available and because muscle spasm associated with acute, painful musculoskeletal conditions is generally of short duration and specific therapy for longer periods is seldom warranted.
  • Prescribing Considerations:
    • Safety and effectiveness of cyclobenzaprine tablets in pediatric patients below 15 years of age have not been established.
