Prozac (fluoxetine) is used for the treatment of several conditions caused by the imbalance of serotonin in the brain. This drug can be recommended to treat depression, panic attacks, some eating disorders, obsessive-compulsive disorder, or premenstrual dysphoric disorder symptoms. It may take you quite some time to notice first results of taking Prozac, but you will need to use it regularly until you do and after that moment on. Make sure you tell your health care provider if you have liver disease, diabetes, seizures, heart disease., a recent history of heart attack, or if you are taking any drugs that have been reported to interact with Prozac, such as insulin or oral medications for diabetes, medications for seizures, anticoagulants, other antidepressants, sedatives, tranquilizers, lithium, nonsteroidal anti-inflammatory drugs, digoxin, medications for anxiety, sleeping pills, antidepressants, or medications for migraine headaches. You may need a dose adjustment, or your doctor will recommend stopping the treatment with some other medicine if it's not critical. Prozac may have side effects - like loss of appetite, nausea, weight loss, nervousness, weakness, changes in sex drive, dry mouth, drowsiness, or sore throat.
