Usage: Prozac is in a class of drugs called selective serotonin reuptake inhibitors. Prozac affects chemicals in the brain that may become unbalanced and cause depression or mood disturbances, eating disorders, or obsessive or compulsive symptoms. Prozac is used to treat depression, obsessive-compulsive disorders, and bulimia (binge eating and purging). Prozac is also used to treat premenstrual dysphoric disorder (PMDD), symptoms of which occur in the week or two before a woman's menstrual period and commonly include irritability, mood swings, and tension as well as the physical symptoms of bloating and breast tenderness.
Directions: Take Prozac exactly as directed by your doctor. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you. Take each dose with water. To ensure that you get the correct dose, measure the oral solution with a dose-measuring cup or spoon, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one. Prozac may be taken with or without food. Try to take Prozac at the same time each day. Take Prozac Weekly on the same day each week as directed by your doctor. Do not stop taking Prozac without first talking to your doctor. It may take several weeks before you to start feeling better.
Side Effects: If you experience any of the following serious side effects, stop taking Prozac and contact your doctor immediately or seek emergency medical treatment: an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives); an irregular heartbeat or pulse; low blood pressure (dizziness, weakness); high blood pressure (severe headache, blurred vision); chills or fever; unusual bleeding or bruising; a rash or hives. If you experience any of the following less serious side effects, continue taking Prozac and talk to your doctor: headache, tremor, nervousness, or anxiety; difficulty concentrating; nausea, diarrhea, dry mouth, or changes in appetite or weight; weakness; increased sweating; sleepiness or insomnia; or decreased sex drive, impotence, or difficulty having an orgasm. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
Precautions: Use caution when driving, operating machinery, or performing other hazardous activities. Prozac may cause dizziness or drowsiness.

Serious, and sometimes fatal, reactions have occurred when these medicines have been used together. Also, do not take Prozac if you are taking thioridazine (Mellaril). Dangerous, even fatal irregular heartbeats may occur if these medicines are taken together. You must wait 5 weeks after stopping Prozac before taking thioridazine (Mellaril).
