What is an antidepressant?
Antidepressants, sometimes in combination with psychotherapy, are often the first treatment people get for depression. If one antidepressant doesn't work well, you might try another drug of the same class or a different class of depression medicines altogether. Your doctor might also try changing the dose. In some cases, your doctor might recommend taking more than one medication for your depression.
What are the different types of antidepressants?
Here are the main types of antidepressants along with brand names:
Selective serotonin reuptake inhibitors (SSRIs) were launched in the mid to late 1980s. This generation of antidepressants is now the most common class used for depression. Examples include citalopram (Celexa), escitalopram (Lexapro), paroxetine (Paxil, Pexeva), fluoxetine (Prozac, Sarafem), vortioxetine (Brintellix), and sertraline (Zoloft). Another SSRI, Viibryd, was approved in early 2011. Side effects are generally mild, but can be bothersome in some people. They include stomach upset, sexual problems, fatigue, dizziness, insomnia, weight change, and headaches.
Serotonin and norepinephrine reuptake inhibitors (SNRIs) are a newer type of antidepressant. This class includes venlafaxine (Effexor), desvenlafaxine (Pristiq and Khedezla), duloxetine (Cymbalta), and, levomilnacipran (Fetzima). Side effects include upset stomach, insomnia, sexual problems, anxiety, dizziness, and fatigue.
Tricyclic antidepressants (TCAs) were some of the first medications used to treat depression. Examples are amitriptyline (Elavil),desipramine (Norpramin, Pertofrane), doxepin (Adapin, Sinequan),imipramine (Tofranil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil), and trimipramine (Surmontil). Side effects include stomach upset, dizziness, dry mouth, changes in blood pressure, changes in blood sugar levels, and nausea.
Monoamine oxidase inhibitors (MAOIs) were among the earliest treatments for depression. The MAOIs block an enzyme, monoamine oxidase. Examples are phenelzine (Nardil), tranylcypromine (Parnate) , isocarboxazid (Marplan), and transdermal selegiline (the EMSAMskin patch). Although MAOIs work well, they're not prescribed very often because of the risk of dangerous reactions. They can cause serious interactions with other medications and certain foods. Foods that can negatively react with the MAOIs include aged cheese and aged meats.
Bupropion (Wellbutrin, Aplenzin) is different than other antidepressants is thought to affect the brain chemicals norepinephrine and dopamine. Side effects are usually mild, including upset stomach, headache, insomnia, and anxiety. Bupropion may be less likely to cause sexual side effects than other antidepressants.
Mirtazapine (Remeron) is usually taken at bedtime. Side effects are usually mild and include sleepiness, weight gain, elevated triglycerides, and dizziness.Trazodone (Desyrel) is usually taken with food to reduce chance for stomach upset. Other side effects include drowsiness, dizziness, constipation, dry mouth,
