Flexeril Tablets
Flexeril® (cyclobenzaprine hydrochloride) is a medication used to treat muscle spasms caused by injuries or other muscle problems.
This prescription muscle relaxant comes in tablet form. Flexeril is taken by mouth, typically three times a day. The medication can cause significant drowsiness, so your healthcare provider may recommend that you take it only at night, especially if you need to be alert during the day.
This drug is available in the following strengths:
- Flexeril 5 mg
- Flexeril 10 mg.
Although it is not entirely clear as to how Flexeril works to treat muscle spasms, it is known that it mostly works in the brain stem (not in the spinal cord and not directly on the muscles). The medication only works to relieve muscle spasms caused by problems in the muscles; it does not help with muscle spasms caused by problems in the brain or spinal cord.
Although most people tolerate Flexeril well, the medication is not suitable for everyone. Some of the common side effects include drowsiness, dizziness, and fatigue.
