“What is the best mood stabilizer for anxiety?”

“Mood stabilizer” is the term used for medications that control the mood swings in bipolar disorder, and they will control both mood swings from normal to mania or depression. If you are bipolar and having the most difficulty with depression, you need a mood stabilizer. Bipolar patients should not take antidepressants unless they are also on a mood stabilizer also. If not, the antidepressant may kick them into a manic episode. In my opinion the best all around mood stabilizer is lamotrigine (Lamictal,) but it has to started at a low dose and increased slowly to avoid a serious but uncommon allergic-like skin rash that turns into boils. Anxiety is best treated with one of the antidepressants that raise brain serotonin (SSRI’s & SNRI’s). and if adjusted properly mirtazapine (Remeron) is most often my first choice, but low doses (15-20mgs) are the most sedating. The best dose is usually 30mg, but going up to 37.5, or down to 22.5mg may be needed.

It depends how severe it is. Occasionally, I use an antidepressant like paxil for chronic anxiety to prevent addiction to Benzodiazepines.
