Several weeks: The side effects of fluoxetine can last more than 2 weeks, because the drug is transformed into an active metabolite norfluoxetine which takes that long to clear half of it from the body. It takes 1-2 months to clear most of it from the body. It may take longer than 2 months to stop having withdrawal symptoms, especially in the elderly, and those with liver disease or drug-drug interactions.
