Product Information
Flexabenz ER (Cyclobenzaprine Extended Release) is a muscle relaxant used short-term to relieve muscle spasms. It is usually prescribed along with rest and physical therapy. The medicine works on the brain and spinal cord to reduce nerve signals that cause tightness, helping muscles relax.
Why is this Medication Prescribed?
Doctors prescribe Flexabenz ER to:
- Relieve painful muscle spasms and stiffness.
- Improve comfort and mobility following injury or muscle strain.
- Support recovery when combined with rest and physical therapy.
Uses
- Relief of muscle spasms and associated pain.
- Improvement of mobility after muscle injury or strain.
- Short-term treatment (generally up to 3 weeks).
Benefits
- Provides effective relief from muscle spasms.
- Enhances recovery when used with physiotherapy and rest.
- Improves comfort and daily functioning.
How Should this Medicine be Used?
- Take by mouth once daily, with or without food, exactly as directed by your doctor.
- Swallow the extended-release capsule whole.
- If unable to swallow whole: open the capsule and sprinkle contents onto a spoonful of applesauce.
- Swallow immediately without chewing.
- Rinse mouth with water and swallow the rinse to ensure full dose is taken.
- Do not prepare the mixture ahead of time.
- Do not crush or chew the capsule — this may release the drug too quickly and increase side effects.
