How long should fluoxetine side effects last?

Depends: The common initial side effects of fluoxetine (dry mouth, upset stomach, nausea, constipation or diarrhea) should go away after two weeks. If they persist, let your doctor know. Other side effects like blurred vision, sweating, sexual side effects can also fade over time, but again, if they last more than two weeks or affect you adversely, talk to you doctor.

Depends: Most people do not experience uncomfortable side effects. Of those that do many find that the side effects abate in a month or so. For some they never go away. Discuss this with your physician as he/she knows more about your health status and can provide more specific information.

Depends: Most minor side effects of fluoxetine resolve in two weeks or less. If they persist after this it may be time to consider changing medications. However, only your prescriber would have the information necessary to help you make this decision. If you have concerns, please contact him/her.
