How to taper antidepressants — guides by medication

Browse hyperbolic taper guides for Zoloft, Effexor, Paxil, Cymbalta, Lexapro, and other SSRIs and SNRIs. Each guide opens the calculator pre-filled for your medication, with drug-specific clinical notes, withdrawal timeline, and dosing tips for the final milligrams — built on Horowitz & Taylor's hyperbolic framework and the Maudsley Deprescribing Guidelines.

⚠️ It's not a substitute for medical advice. This calculator can help you visualise a tapering schedule but before making any changes to your medication plan it's necessary to consult a medical professional. Ask a psychiatrist — available after you request your protocol.

Why tapering differs by medication

Antidepressants are not interchangeable when stopping. Half-life, transporter occupancy curve shape, and available formulations all change how large each milligram reduction feels. The Henssler 2024 meta-analysis found discontinuation symptoms in a large fraction of patients — but incidence varies several-fold between drugs. Paroxetine and venlafaxine consistently rank highest; fluoxetine lowest.

Hyperbolic tapering (Horowitz & Taylor, 2019) spaces reductions by equal occupancy steps, not equal milligrams — which matters most in the final milligrams when linear cuts cause the largest jumps. Each guide below applies that method to one drug's pharmacology and your region's tablet, liquid, and compounding options.

Withdrawal risk tiers — where to start

A rough guide to expected difficulty. Your prescriber and the pre-taper risk quiz refine the starting speed preset.

  1. 1

    Higher withdrawal risk — start slower (preset C typical)

    Short half-life, steep occupancy curves, and highest discontinuation incidence in meta-analyses. Plan for liquid, compounded, or taper-strip formulations for the final milligrams.

    Evidence: Henssler 2024; Horowitz 2024

  2. 2

    Moderate withdrawal risk — preset B typical

    Common first-line SSRIs with moderate discontinuation reports. Liquid drops or compounding may still be needed below the lowest tablet strength.

    Evidence: Henssler 2024; Horowitz 2019

  3. 3

    Lower withdrawal risk — often more forgiving steps

    Long half-life or lower discontinuation incidence in surveys. Still taper hyperbolically — linear cuts in the last milligrams can still cause symptoms.

    Evidence: Henssler 2024; Davies 2019

What each medication guide includes

  • Drug-specific clinical notes — bead counting (duloxetine), liquid dosing (paroxetine, escitalopram), taper strips (Netherlands)
  • Withdrawal timeline and FAQs — cited to peer-reviewed sources
  • Links to tools — symptom checker, brain zaps explainer, and full methodology

Frequently asked questions about tapering by medication

Plain-English answers with citations — which drugs are hardest, why guides differ, and when to start slower.

  • Which antidepressant is hardest to taper?

    Population data consistently rank short-half-life agents at the top of the withdrawal-symptom table: paroxetine (Paxil/Seroxat), venlafaxine (Effexor), duloxetine (Cymbalta), and desvenlafaxine (Pristiq). Fluoxetine (Prozac) sits at the bottom because its long half-life effectively self-tapers. The Henssler 2024 Lancet Psychiatry meta-analysis is the most recent large synthesis; the Maudsley Deprescribing Guidelines (Horowitz & Taylor, 2024) translate this into per-drug taper defaults.

  • Why does each drug need its own tapering guide?

    Antidepressants differ in half-life, dose–occupancy curve steepness, available formulations (tablets, liquids, beads, taper strips), and default withdrawal risk. A 10% linear reduction that works for sertraline may produce disproportionate occupancy jumps for paroxetine in the final milligrams. Each Claro guide pre-fills the hyperbolic calculator with drug-specific pharmacology (K_app, E_max), formulation data for your region, and clinical notes for the last steps.

  • How do I taper off Zoloft (sertraline)?

    Sertraline has a moderate withdrawal profile compared with paroxetine or venlafaxine. Most people use a hyperbolic schedule at preset B (~2.5% occupancy drop per step, 2-week holds). Liquid formulations (e.g. Rosemont sertraline oral suspension in the UK) help with the final milligrams. Open the sertraline guide to pre-fill the calculator and read drug-specific notes.

  • How do I taper off Effexor (venlafaxine)?

    Venlafaxine is among the hardest SNRIs to stop because of its short half-life and steep dose–occupancy curve. Most guides recommend preset C (~1.5% occupancy drop, 4-week holds) and liquid or compounded formulations early. Never stop venlafaxine abruptly — brain zaps and dizziness are common with large steps. Use the venlafaxine guide for a pre-filled schedule.

  • Can I use the same taper speed for every SSRI?

    No. The calculator defaults paroxetine, venlafaxine, and duloxetine to slower preset C because of their pharmacology and withdrawal incidence. Fluoxetine often tolerates faster steps. Your individual situation (duration on drug, prior failed tapers, missed-dose sensitivity) also matters — use the pre-taper risk quiz to pick a starting preset, then adjust with your prescriber based on symptoms.

  • What if my medication is not listed?

    The hub lists the SSRIs and SNRIs with the strongest evidence base in the calculator today. If your drug is not listed, please do not try to substitute a different medication yourself — the safest approach is to discuss a bespoke taper with your prescriber. You can also let us know which medication you need at [email protected] and we will prioritise it. We add drugs once we have verified formulation data and PET occupancy anchors for each supported region.

  • Are these guides a substitute for medical advice?

    No. Each guide is an educational visualization based on published pharmacology and regional formulary data. Every dose change should be supervised by a qualified prescriber. NICE NG222 (2022) and the Royal College of Psychiatrists (2020) recommend stopping antidepressants only with clinical support.

This schedule is a map, not a rule. Wait until symptoms from the previous step have settled before reducing again — and review every change with your prescriber.
