Types

Lithium is the most often prescribed mood stabilizer. Atypical antipsychotics such as olanzapine and risperidone and anticonvulsants such as valproate, carbamazepine and lamotrigine are used to control mood polarities, as well.
Mechanisms
-
It is believed that lithium elevates levels of brain serotonin and thereby stabilizes mood. There is less research to explain the properties of anticonvulsants and atypical antipsychotics.
Considerations
-
These medications can cause extreme side effects. Most cause nausea and weight gain. Lithium can be toxic. Patients who take mood stabilizers should undergo therapy to discuss the importance of medication compliance.
