Fluoxetine is also prescribed for the treatment of premenstrual dysphoric disorder
(PMDD), formerly known as premenstrual syndrome (PMS). Symptoms of PMDD include mood problems such as anxiety, depression, irritability or persistent anger, mood swings, and tension. Physical problems that accompany PMDD include bloating, breast tenderness, headache, and joint and muscle pain. Symptoms typically begin 1 to 2 weeks before a woman’s menstrual period and are severe enough to interfere with day-to-day activities and relationships. 

Fluoxetine is a member of the family of drugs called “selective serotonin re-uptake inhibitors.” Serotonin is one of the chemical messengers believed to govern moods. Ordinarily, it is quickly reabsorbed after its release at the junctures between nerves. Re-uptake inhibitors such as Fluoxetine slow this process, thereby boosting the levels of serotonin available in the brain.
