Relaxes your muscles.

Dantrium (dantrolene) effectively treats malignant hyperthermia (increased temperature and muscle contractions when receiving anesthesia) and is the only medicine used to treat the condition. Dantrium (dantrolene) is not a first-choice treatment for general muscle spasms because it can damage your liver.
