What is this Drug Used For?

nerve impulses (or pain sensations) that are sent to your brain
and is used together with rest and physical therapy to treat
skeletal muscle conditions such as pain or injury.
How Do I take my Flexeril?
Take Flexeril (Cyclobenzaprine) by mouth usually 3 times a day,
or as directed by your doctor. Take this medicine with a full
glass of water. Do not crush, chew, break, or open an extended-release
capsule. Swallow the pill whole. Breaking or opening the pill
may cause too much of the drug to be released at one time. Dosage
is based on your medical condition and response to therapy. Do
not increase your dose or take it more often than prescribed

no longer than 3 weeks, unless otherwise directed by your doctor.

What Precautions should I observe before taking Flexeril?

use caution performing tasks requiring alertness such as driving.
