Why does Prozac withdrawal show up weeks later?

Fluoxetine is the slow one. The parent drug takes about four to six days to fall by half, it turns into an active leftover that lingers even longer, and it takes roughly 25 days after the last dose to be almost fully gone. Paroxetine and sertraline clear in about a day. This episode works through what that difference does to the experience of coming off it.

We cover why withdrawal from fluoxetine often shows up late, sometimes a week or two after a dose change; what those symptoms can look like, from dizziness and flu-like feelings to sleep trouble, irritability and electric shock sensations; and how to tell a withdrawal wave from a return of depression, which tends to build more gradually and keep going. We also walk through the taper itself: coming down in stages, leaving a few weeks between reductions, making the cuts smaller as the dose gets low, and using the capsule, tablet or liquid strengths that let you measure a small dose near the end. There is a section on the fluoxetine bridge, where a shorter-acting antidepressant is switched to fluoxetine first so its slower clearance blunts the withdrawal.
