Dantrolene Sodium Information
(dan' troe leen)
Dantrolene can cause severe liver damage. Do not use dantrolene for conditions other than those recommended by your doctor. Do not take more than the recommended amount prescribed by your doctor. Do not take dantrolene if you have liver disease. If you experience any of the following symptoms, call your doctor immediately: yellowing of the skin or eyes, dark urine, black tarry stools, nausea, vomiting, loss of appetite, pain in the upper right part of the stomach, or unusual bruising or bleeding.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests before and during your treatment to check your response to dantrolene.
Dantrolene is used to treat spasticity (muscle stiffness and tightness) or muscle spasms associated with spinal cord injuries, stroke, multiple sclerosis, or cerebral palsy. It is also used to prevent, treat, or reduce the risk of malignant hyperthermia (disorder that causes a fast rise in body temperature and muscle contractions), Dantrolene is in a class of medications called skeletal muscle relaxants. Dantrolene acts on the spinal cord nerves to treat spasticity and to prevent and treat malignant hyperthermia.
Dantrolene comes as a capsule to take by mouth. When used to treat spasticity, it is usually taken once a day for 7 days and then increased gradually every 7 days to three to four times a day. When used to prevent malignant hyperthermia, it is usually given three to four times a day, starting 1 or 2 days before surgery. When used after a malignant hyperthermia crisis, it is usually given in 4 divided doses for 1 to 3 days . Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dantrolene exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of dantrolene for spasticity and gradually increase your dose, not more than once every 7 days. If your symptoms do not improve or get worse within 45 days of taking dantrolene, call your doctor.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
