This medication is used to treat muscle tightness and cramping (spasms) caused by certain nerve disorders such as spinal cord injury, stroke, cerebral palsy, and multiple sclerosis. It works by relaxing the muscles. Dantrolene helps reduce muscle pain and stiffness, improves your ability to move around, and lets you do more of your daily activities.
Dantrolene is also used with other treatments to prevent or treat special cases of high fever (malignant hyperthermia) related to anesthesia and surgery.
How To Use

Dosage is based on your medical condition, response to therapy, and in some cases weight. For the prevention and treatment of malignant hyperthermia, treatment lasts for several days.
