Mood stabilizers are safe when used under the close supervision of a medical professional. There are a number of side effects associated with the use of mood stabilizers that may be life threatening if not taken as directed, according to WebMD.
The Food and Drug Association has issued a warning on a specific type of mood stabilizers called anticonvulsants; however, it does not recommend that people stop taking these medicines. These drugs have been known to increase the risk of a person having suicidal thoughts and committing suicide. The patient should be watched closely for signs of these symptoms. Once the treatment is complete, the patient should slowly reduce the amount of the medicine taken, under his caregiver's direction, to avoid serious side effects.
