- Tricyclic antidepressants: Protriptyline (Vivactil), clomipramine (Anafranil), imipramine (Janimine, Tofranil), and desipramine (Norpramin, Pertofrane)
- Selective serotonin reuptake inhibitors (SSRIs): Fluoxetine (Prozac), paroxetine (Paxil), and sertraline (Zoloft)
- Newer antidepressants: Venlafaxine (Effexor)
Tricyclics were the first antidepressants used for cataplexy; they were also one of the first treatments for cataplexy. They can be helpful for some patients but have many unpleasant side effects, including dry mouth, constipation, and weight gain. Tricyclics can also lower blood pressure and cause disturbances in heart rhythm.
SSRIs have fewer side effects than tricyclics but may not work as well for cataplexy control. The most common side effects include nausea, drowsiness or insomnia, headache, weight gain, and sexual dysfunction.
Venlafaxine (Effexor) is a selective serotonin and norepinephrine reuptake inhibitor (SSNRI) that has shown promising results for treatment of cataplexy. Some patients with narcolepsy, and their doctors, report that venlafaxine seems to work best of all the antidepressants.
Monoamine Oxidase Inhibitors (MAOIs). Selegiline (Eldepryl, Movergan), also known as deprenyl, is an MAOI that blocks monoamine oxidase B, an enzyme that degrades dopamine. MAOIs may play a role in narcolepsy, but how much benefit this group of drugs provides is not well proven.
Selegiline has significant side effects:
- It interacts with nearly every antidepressant. Patients suffering from depression should discuss all treatment options with their doctor.
- People taking any monoamine oxidase inhibitor are at risk for high blood pressure if they consume tyramine-containing foods or beverages, including aged cheeses, most red wines, vermouth, dried meats and fish, canned figs, fava beans, and concentrated yeast products.
