Antidepressant Withdrawal Timeline
What to expect, phase by phase — personalized to your medication, how long you've taken it, and how you're coming off.
Withdrawal Timeline Generator
A personalized phase-by-phase map of what antidepressant withdrawal typically looks like for your situation.
Widths are proportional to typical phase length for your inputs — not to intensity, which generally decreases left to right.
Onset
2–7 days after each cutAfter each reduction, Sertraline levels take 2–7 days to settle — which is why a cut can feel fine at first and catch up with you days later. Judge every cut at the END of its hold.
Acute phase
The first 1–2 weeks after larger cutsA gradual taper spreads the acute phase out into much smaller, repeated adjustments — this is the entire point of tapering. Most people describe post-cut symptoms as a muted version of acute withdrawal.
Subacute recovery
Months 1–2Symptoms become intermittent rather than constant — the windows-and-waves pattern emerges. Waves still feel convincing, but windows lengthen. Sleep usually begins consolidating during this phase.
Stabilization
Months 2–4Most people report substantial recovery in this window: waves become shorter, milder, and further apart. Continued gentle routines (sleep timing, daylight, low stimulants) support the tail end.
These ranges are drawn from the antidepressant discontinuation literature — they describe typical patterns, not guarantees. Dose, taper speed, other medications, and individual biology all shift the picture. A slower taper compresses intensity, not the calendar. If you stopped abruptly and feel severely unwell — or if you have any thoughts of harming yourself — contact your prescriber or seek urgent medical help immediately.

How this timeline is built
The phases and ranges follow the antidepressant discontinuation literature, including the hyperbolic tapering research of Horowitz & Taylor: onset timing scales with your medication's half-life, and the length of the later phases scales with duration of use. It's a map of the typical territory — individual experiences vary in both directions, and a significant minority sail through far faster than these ranges suggest.
The single most important thing the research agrees on: how you come off matters more than what you come off. Gradual, symptom-led tapering — the approach our taper schedule builder plans — consistently produces milder journeys than abrupt discontinuation. Pair this timeline with the symptom & sleep tracker to watch your own windows and waves against the map.
Frequently asked questions
How long does antidepressant withdrawal last?
It varies more than most sources admit. Symptoms commonly begin within days of a reduction, are most intense in the following one to two weeks, and ease from there — but after long-term use a minority experience milder, intermittent symptoms for considerably longer. The strongest factor you control is taper speed: gradual reductions with adequate holds reliably produce milder and shorter symptoms than rapid ones.
Does the timeline differ between Effexor and Prozac?
Mainly at the start, and dramatically so. Venlafaxine (Effexor) has a ~5-hour half-life, so levels fall within hours and symptoms can appear the same day. Fluoxetine (Prozac) has a half-life of days, with an active metabolite lasting longer still, so it declines gently on its own and symptoms may not appear for a week or more. The later phases look broadly similar; it's the onset that differs.
Does tapering slowly shorten withdrawal?
It changes the intensity more than the calendar. A gradual taper spreads the adjustment across many small steps instead of one large one, so what you experience is a series of manageable adjustments rather than a single severe episode. Total time on the taper is longer, but the difficulty at any given moment is far lower — and fewer people abandon the attempt and have to start over.
What are 'windows and waves'?
As withdrawal progresses, symptoms often become intermittent: windows of feeling near-normal alternate with waves of returning symptoms. Waves feel like setbacks but are a commonly reported feature of recovery rather than evidence that something has gone wrong. Over time, windows typically lengthen. Tracking day to day is the most reliable way to see a trend that's invisible from inside a wave.
How do I tell withdrawal from relapse?
It's the central difficulty in antidepressant tapering, and it warrants your prescriber's input. Broadly: discontinuation symptoms tend to appear within days of a dose change, often carry physical features (dizziness, 'brain zaps', nausea, flu-like feelings) that a depressive episode usually doesn't, and typically settle if you hold at a stable dose. Relapse tends to build over weeks and resembles your original episode. Holding rather than descending further is a reasonable way to gather information.
