Cyclobenzaprine (Flexeril) is a muscle relaxant effective in relieving pain from skeletal, muscular injuries that arise from the respective muscle and not the nerve. It acts via intricate mechanisms in the central nervous system, particularly the brainstem, to inhibit pain conduction from the peripheral nerves to the brain.
Cyclobenzaprine Hcl is a drug used in the treatment of muscle pain or injury. It may also be used to treat muscle spasms and, in some cases, it is used off-label in the treatment of fibromyalgia.
The drug works by inhibiting nerve signals to major muscle groups, thereby preventing the body from feeling the sensations of pain or injury from those muscles.
Cyclobenzaprine Hcl is only available by the oral route. It is not recommended in patients who have suffered from congestive heart failure, heart rhythm disorders, or in patients who have experienced a heart attack.
Common side effects with cyclobenzaprine Hcl include a headache, dizziness, drowsiness, blurred vision, and nausea.
