    Monoamine Oxidase Inhibitors (MAOIs) for Bipolar Disorder

    Monoamine oxidase inhibitors are an extremely potent class of antidepressants that treat depression by preventing the breakdown of serotonin, dopamine, and norepinephrine in the brain, increasing their availability. These medications are not used often because of their potential for drug interactions that can lead to problems with blood pressure as well as the need to avoid foods that contain the amino acid tyramine. Generally, like most antidepressants, MAOIs should be used for bipolar depression only in combination with a mood stabilizer such as lithium or valproate, to minimize the risk of inducing mania.

    Antidepressants in this class of drugs that can be used for bipolar depression include:

    Among these, Parnate has been the most extensively studied specifically in bipolar depression, leading in one randomized trial to improvement in over 80% of subjects. Like other classes of antidepressants, the MAOIs take several weeks to begin working. Your doctor may also prescribe a sedative to help relieve anxiety, agitation, or sleep problems while the antidepressant begins to work. You will also need to monitor what foods you eat to avoid side effects.

    MAOI Side Effects

    Eating certain smoked, fermented, or pickled foods, drinking certain beverages, or taking certain medications can cause severe, sudden high blood pressure in combination with MAOIs. People taking these antidepressants must follow a special diet.

    Common side effects of MAOIs may include:
