Flesseril

Cyclobenzaprine is primarily prescribed as a short-term adjunct (2-3 weeks maximum) to rest and physical therapy for relief of muscle spasm associated with acute, painful musculoskeletal conditions. It is not effective for muscle spasm due to central nervous system disease. Overdose can cause anticholinergic toxicity including delirium, tachycardia, dry mouth, and urinary retention. There is risk of serotonin syndrome when combined with serotonergic drugs. Use with caution in elderly patients due to increased risk of confusion, cognitive impairment, and cardiac events.
