In addition, Celexa may have a particular benefit for people who are binge eaters or overeaters or who have bulimia (a problem in which people binge and then purge or vomit). There is some evidence that SSRIs can help people feel full when they're eating, possibly preventing overeating. Decreased appetite is a common side effect of Celexa, making it potentially a good treatment for people who eat too much but perhaps not a good choice for someone who doesn't eat enough (people with anorexia nervosa, for example).
Celexa is approved by the Food and Drug Administration (FDA) for treating major depressive disorder. Treating eating disorders is considered an "off-label" use of the drug.
