2 wks: I am not sure if you mean the 3 doses of Prozac were taking at the same time or different days. It usually takes 2 wks to wash Prozac out of the system b/c of the long half life of the active metabolite of prozac, norfluoxetine.

4 to 5 weeks: Prozac (fluoxetine) has a half life of 7 days and it takes at least 4 half lifes or more to clear your body.

More than 2 weeks: The half life of this medication is as long as three days. It will be out of your system in 15 days depending on individual factors related to the patient. Ask your prescriber.
