Fluoxetine

Fluoxetine (Prozac) is used to treat depression, obsessive-compulsive disorder (bothersome thoughts that won't go away and the need to perform certain actions over and over), some eating disorders, and panic attacks (sudden, unexpected attacks of extreme fear and worry about these attacks). Fluoxetine (Sarafem) is used to relieve the symptoms of premenstrual dysphoric disorder, including mood swings, irritability, bloating, and breast tenderness. Fluoxetine is in a class of medications called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance.

Fluoxetine (Prozac) comes as a capsule, a tablet, a delayed-release (long-acting) capsule, and a solution (liquid) to take by mouth. Fluoxetine may be taken with or without food. Fluoxetine (Sarafem) comes as a capsule to take by mouth. Fluoxetine (Prozac) capsules, tablets, and liquid are usually taken once a day in the morning or twice a day, in the morning and at noon. Fluoxetine delayed-released capsules are usually taken once a week. Fluoxetine (Sarafem) is usually taken once a day, either every day of the month or on certain days of the month. Take fluoxetine at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluoxetine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor may start you on a low dose of fluoxetine and gradually increase your dose.

It may take 4 to 5 weeks or longer before you feel the full benefit of fluoxetine. 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.

Your doctor will probably tell you that you should not take fluoxetine. If you stop taking fluoxetine, you should wait at least 5 weeks before you begin to take thioridazine or a monoamine oxidase inhibitor.
