Somone who has been taking fluoxetine for a long period of time is much more likely to experience withdrawal than someone who has been on it short term. Prozac (fluoxetine) has a: very long half-life and its active metabolite also has a long half-life which means it is active in the body for a long time. The second half-life adds another 100 mg equivalents to the 50 mg (the half that remains after the first half-life) for a total of 150, which halves to 75 mg circulating equivalent.
