What the evidence actually says about stopping antidepressants
The mainstream advice for years — taper over two to four weeks and you'll be fine — was based on thin evidence and contradicted by what patients were experiencing. We reviewed the most current clinical research, including a landmark 2019 paper in Therapeutic Advances in Psychopharmacology that challenged standard tapering guidance, as well as systematic reviews of discontinuation syndrome prevalence, expert psychiatric guidance, and the lived experience of patients who have successfully come off these medications. Our standard is the best available evidence, not the oldest official recommendation.
-
Discontinuation syndrome prevalence confirmed A 2019 systematic review in Addictive Behaviors found that 56% of people who stop antidepressants experience discontinuation symptoms, and 46% describe them as severe — far higher than older estimates of around 20%.
-
Hyperbolic tapering mechanism verified Research by Horowitz and Taylor (2019) demonstrated that serotonin transporter occupancy follows a hyperbolic relationship with dose — meaning small dose reductions at low doses have a proportionally larger neurological effect, which explains why standard equal-step tapers cause the most symptoms near the end.
-
Antidepressant-specific risk differences reviewed Shorter half-life antidepressants — particularly paroxetine (Paxil) and venlafaxine (Effexor) — are consistently documented as having the highest risk of discontinuation symptoms; longer half-life drugs like fluoxetine (Prozac) carry significantly lower risk due to self-tapering pharmacokinetics.
-
Standard guideline limitations acknowledged Both the Royal College of Psychiatrists (UK) and the Royal Australian and New Zealand College of Psychiatrists have updated their guidance to recommend longer, more individualised tapers, explicitly departing from the older two-to-four-week standard — a sign the evidence shifted and institutions followed.
The right taper depends on your medication, your dose, and how long you've been on it
There's no single taper schedule that works for every antidepressant and every person — but the principles are consistent, and the options below map to the most common situations.
What people commonly try that makes stopping harder
Most of the approaches that backfire aren't obviously wrong — they're things that sound reasonable but ignore how antidepressants actually interact with brain chemistry.
-
Stopping cold turkey — Abruptly stopping an SSRI or SNRI can trigger discontinuation syndrome within 24–72 hours: dizziness, "brain zaps," intense nausea, irritability, and in some cases a severe and frightening emotional crash that people often mistake for relapse. This is especially dangerous with paroxetine and venlafaxine, where symptoms can appear within hours of a missed dose.
-
Cutting tablets in half as the only taper step — Going from your full dose to half a tablet and then to nothing is an improvement over stopping cold turkey, but it still typically halves the dose in one step and then eliminates it entirely — which hits the brain's serotonin receptors hard at exactly the point where sensitivity is highest. This two-step approach is responsible for most people's "I tried to taper and it still felt awful" experiences.
-
Following a fixed schedule regardless of symptoms — Some people receive a taper schedule from their doctor and follow it rigidly even as discontinuation symptoms pile up, assuming they just have to push through. The evidence-based approach is the opposite: if symptoms appear after a dose reduction, hold at that dose until they resolve before reducing further. A taper is not a race — the schedule should serve you, not the other way around.
-
Assuming any distress after stopping means you need to restart — Discontinuation symptoms and a genuine return of depression can look similar on the surface, but they behave differently: discontinuation symptoms typically begin within 2–5 days of a dose reduction and improve if the dose is temporarily raised; a depressive relapse tends to emerge more gradually after 2–4 weeks and does not improve quickly with a temporary dose increase. Knowing the difference helps you and your doctor make the right call instead of restarting medication you no longer need.

I'd been on sertraline 100mg for four years and had tried to come off it twice before — both times the brain zaps and insomnia drove me straight back. This time my psychiatrist used a liquid formulation and we went really slowly: 100mg → 75 → 50 → 37.5 → 25 → 18 → 12 → 8 → 5 → 2.5 → 0 over about eight months. The final few steps were almost imperceptible. I've been off it for six weeks now and feel genuinely fine — better than either of my previous attempts at the two-week taper.

Was on escitalopram 20mg for about 18 months. My GP initially suggested dropping to 10mg for two weeks then stopping. I pushed back after reading about hyperbolic tapering and she agreed to extend the process. We went 20 → 15 → 10 → 7.5 → 5 → 2.5 → 0 over 14 weeks, spending three weeks at each step. I had some mild dizziness at the 5mg step that lasted about ten days, but I held there until it passed and the rest was smooth. Genuinely surprised how manageable it was with a proper schedule.

I'm still in the process — coming off venlafaxine 150mg which everyone warned me was the hardest. My psychiatrist switched me to fluoxetine first to make use of the longer half-life, and that transition was rougher than I expected for about three weeks. Now I'm tapering the fluoxetine down slowly and so far it's much gentler than my two previous attempts at tapering the venlafaxine directly. Not finished yet, but I feel like I'm finally doing it the right way. Wish someone had told me about the fluoxetine bridge years ago.
