Commonly prescribed antidepressants include selective serotonin reuptake inhibitors, claims About.com. SSRIs work by preventing the reuptake of a neurotransmitter known as serotonin. Types of selective serotonin reuptake inhibitors include Prozac, Celexa, Zoloft and Lexapro. SSRIs have fewer side effects than older versions of antidepressants.
Other types of antidepressants include serotonin and norepinephrine reuptake inhibitors, such as Pristiq, Cymbalta and Effexor XR, and tricyclic antidepressants, such as Pamelor and Vivactil, according to Healthline. Tricyclic antidepressants are usually prescribed when other antidepressants do not work. Additional types of antidepressants include dopamine reuptake blockers, such as Wellbutrin, and monoamine oxidase inhibitors such as Nardil and Emsam.
