Mood stabilizers are medications primarily used to treat mood disorders, such as bipolar disorder. They help regulate extreme mood swings, reducing episodes of mania and depression. Common mood stabilizers include lithium, valproate, and lamotrigine. These medications work by balancing chemicals in the brain, promoting emotional stability. While they can be effective, mood stabilizers may have side effects, such as weight gain or gastrointestinal issues. Regular monitoring by a healthcare professional is essential to ensure safety and effectiveness during treatment.
