Antidepressants are not considered addictive. They do not create cravings nor are they associated with drug-seeking behavior. Although people sometimes refer to the symptoms they experience when stopping an antidepressant too rapidly -- such as fatigue, nausea and dizziness -- as withdrawal, it is not considered a true withdrawal syndrome. These flu-like symptoms are more accurately referred to as discontinuation syndrome.
