In brief: Quite a while

Prozac (fluoxetine) taken over a period of three or more months, then stopped, can show the presence of fluoxetine for five or more weeks.
Prozac has both a right and left isomer (like looking at yourself in the mirror and raising your hand and watching your raised r hand appear to be your l hand). Breakdown of fluoxetine yields nor-fluoxetine which lasts 2 x as long in the body as fluoxetine.
