Cyclobenzaprine Hydrochloride

Locally acting Skeletal Muscle Relaxants Prescription

Indications

Pain Muscle Spasm

Flexor is used together with rest and physical therapy to help ease muscle spasms that occur with sudden, painful musculoskeletal conditions. As it takes effect, patients typically notice the spasm easing along with the pain, tenderness, and stiffness that come with it, allowing for better movement and an easier return to daily activities.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Cyclobenzaprine is a skeletal muscle relaxant that works mainly on the central nervous system, not directly on the muscle itself. Its chemical structure is close to that of the tricyclic antidepressants, so the two groups share some properties. The medicine acts on the brain stem, where it reduces tonic somatic motor activity. In doing so it affects both the α and δ motor systems. Doctors usually prescribe it as an add-on treatment to ease painful muscle spasms that come with musculoskeletal conditions.

Pregnancy & Breastfeeding

Pregnancy Category B. Cyclobenzaprine Hydrochloride should be used during pregnancy only if the potential benefit clearly justifies the possible risk. Nursing mothers should use this medicine with caution.
