Rarely, dantrolene may cause very serious (possibly fatal) liver problems. The risk is greater if you use high doses of dantrolene (over 400-800 milligrams per day), or are female, older than 35 years, or taking other medications. Signs of liver problems usually appear between 3-12 months of treatment. To reduce your risk of this side effect, you should have regular liver tests checked by your doctor. Tell your doctor right away if you develop any of the following symptoms of liver disease: persistent nausea/vomiting, stomach/abdominal pain, dark urine, yellowing eyes/skin, unusual tiredness.
To further reduce your risk of side effects, do not increase your dose or take it more often or for longer than prescribed. The lowest effective dose should be used. The manufacturer recommends that if your condition does not improve after 45 days of treatment, your doctor must be notified and dantrolene should be stopped.
