Prozac (fluoxetine) is an antidepressant medicine specially intended for the treatment of conditions caused by the imbalance of chemicals. Suicidal thoughts are sometimes reported in younger people that start taking Prozac. If you are younger than 24 your health care provider will want to see you for regular health check ups to make sure you get all the benefits of your treatment. Make sure you show up for your doctor's regular appointments for your condition to be monitored. Your dose may need to be changed occasionally for you to benefit from the treatment as much as possible. However, do not change the dose yourself to avoid health consequences. You may need up to 4 weeks to get all the benefits of your treatment, so make sure you keep on taking Prozac regularly to maintain this medicine at the same level in your bloodstream. Some side effects are possible, such as stuffy nose, weight changes, dry mouth, upset stomach, increased appetite, sore throat, impotence, drowsiness, mild nausea, sleep problems, constipation, or dizziness. However, in most cases they will just go away on their own. Please check with your doctor before taking any other medications along with Prozac, especially any of the following ones: seizure medication, haloperidol, clopidogrel, alprazolam, clozapine, blood thinners, or other antidepressants.
