Generic Prozac(Generic name: Fluoxetine)
Why is Prozac prescribed?Prozac is prescribed for the treatment of depression—that is, a continuing depression that interferes with daily functioning. The symptoms of major depression often include changes in appetite, sleep habits, and mind/body coordination; decreased sex drive; increased fatigue; feelings of guilt or worthlessness; difficulty concentrating; slowed thinking; and suicidal thoughts. Prozac is also prescribed to treat obsessive-compulsive disorder. An obsession is a thought that won't go away; a compulsion is an action done over and over to relieve anxiety. The drug is also used in the treatment of bulimia (binge-eating followed by deliberate vomiting). It has also been used to treat other eating disorders and obesity. In addition, Prozac is used to treat panic disorder, including panic associated with agoraphobia (a severe fear of being in crowds or public places). People with panic disorder usually suffer from panic attacks—feelings of intense fear that develop suddenly, often for no reason. Various symptoms occur during the attacks, including a rapid or pounding heartbeat, chest pain, sweating, trembling, and shortness of breath. In children and adolescents, Prozac is used to treat major depression and obsessive-compulsive disorder. Prozac Weekly is approved for treating major depression. Under the brand name Sarafem, the active ingredient in Prozac 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. Prozac belongs to the class of drugs called selective serotonin re-uptake inhibitors (SSRIs). 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 Prozac slow this process, thereby boosting the levels of serotonin available in the brain.

Continue to take fluoxetine even if you feel well. Do not stop taking fluoxetine without talking to your doctor. If you suddenly stop taking fluoxetine, you may experience withdrawal symptoms such as mood changes, irritability, agitation, dizziness, numbness or tingling in the hands or feet, anxiety, confusion, headache, tiredness, and difficulty falling asleep or staying asleep. Your doctor will probably decrease your dose gradually. How should you take Prozac?Prozac should be taken exactly as prescribed by your doctor. Prozac usually is taken once or twice a day. To be effective, it should be taken regularly. Make a habit of taking it at the same time you do some other daily activity. It may be 4 weeks before you feel any relief from your depression, but the drug's effects should last about 9 months after a 3-month treatment regimen. For obsessive-compulsive disorder, the full effect may take 5 weeks to appear.
