About Prozac
Uses of Prozac
Fluoxetine is used to treat depression, bulimia (an eating disorder), obsessive compulsive disorders (OCD), and severe symptoms of premenstrual syndrome (premenstrual dysphoric disorder-PMDD). Prozac works by helping to restore the balance of certain natural chemicals in the brain.

Some medical conditions may require a different dosing schedule (e.g., twice daily in the morning and at noon) as determined by your doctor. Take this medication exactly as prescribed. It is important to continue taking Prozac even if you feel well. Also, do not stop taking Prozac without consulting your doctor. It may take up to 4 weeks before the full benefit of Prozac takes effect.
