Atypical antidepressants

These medications are called "atypical" because they don't fit neatly into other categories. Generally, atypical antidepressants cause fewer sexual side effects than other antidepressants do. Atypical antidepressants include:

Bupropion

Brand-name and generic bupropion tablets are available in three forms: Wellbutrin, Wellbutrin SR and Wellbutrin XL or XR.

Bupropion has shown some success in treating social anxiety disorder and anxiety comorbid with depression, but not panic disorder with agoraphobia.

The bupropion treatment course lasts for seven to twelve weeks, with the patient halting the use of tobacco about ten days into the course. Bupropion approximately doubles the chance of quitting smoking successfully after three months.

Trazodone

This mild antidepressant is often prescribed as a sleep aid because it can be very sedating.

Warnings:

If the patient has a known hypersensitivity to trazodone.
If the patient is under eighteen years of age and combines with other antidepressant medications it may increase the possibility of suicidal thoughts or actions

Mirtazapine

The potential for dangerous drug interactions with mirtazapine is considered to be very low, if not completely negligible. As a serotonin receptor antagonist, mirtazapine will not cause serotonin syndrome at any dose

Nefazodone.

This antidepressant is effective, but isn't commonly prescribed because it has been linked to dangerous liver problems.

Nefazodone's claimed advantages over other antidepressants include reduced possibility of disturbed sleep or sexual dysfunction, and ability to treat some patients who did not respond to other antidepressant drugs.
