Antidepressive medicines usually do not help in the acute stages of
anorexia nervosa. But recent studies indicates that Prozac can prevent
anorexia from recurring again, after the patient has achieved normal
weight. Two-thirds of former anorectics who used Prozac after achieving
normal weight, did not get anorexia again, while only 16 % could avoid
recurrence of anorexia among those who were treated with placebo.
