Prozac (fluoxetine): Unless advised by your physician you should not stop Prozac (fluoxetine) if you have anxiety or depression it will help your brain and hormones.

Prozac (fluoxetine): You should not stop Prozac (fluoxetine) abruptly as you can negative reactions. If you are discontinuing consult with your doctor for a healthy plan to titrate over time. Depending how long you have been on this medication it can take several weeks to discontinue without symptoms. My best.
