Welcome!We have helped more than 46,000 people safely stop taking duloxetine (Cymbalta) since 2013. This site was built by people who have been exactly where you are right now. How Antidepressants Work in the BrainThe most important thing to understand is this: duloxetine and other antidepressants do not work like many medicines where half the dose means half the effect. Stopping abruptly, skipping doses, or following a fast doctor-directed taper is likely to cause withdrawal, which for many can be severe and long-lasting. There is a better way called a Hyperbolic Taper. A hyperbolic taper reduces an antidepressant by smaller and smaller amounts over time. A dose reduction may feel easier at higher doses. But at lower doses, the brain and body can react more strongly, even to a small decrease. This can lead to life-changing withdrawal symptoms. This is represented by a hyperbolic curve on the graph below. Use the menu above to find exactly where you are:

Who We Are
We are volunteers. Many of us, or our loved ones, have taken duloxetine and had a hard time stopping it, or are still tapering. We went through withdrawal and learned things most doctors are not taught. We also learned things that are not clearly explained in the pharmacy inserts. We have moderated the largest peer support group in the world for coming off duloxetine. We are respected by leading deprescribing specialists and consult directly with them.
Since 2013, we have guided tens of thousands of people through a safe and slow taper off duloxetine. The hyperbolic method is backed by the published research of leading deprescribing experts, including Mark Horowitz MD, PhD, Anders Sørensen PhD, and others listed on our Experts, Research, and Resources page.
We have no financial interest in any drug company, supplement brand, or pharmacy. This website runs on donations and volunteer time. Please consider donating to support our website, IT, and annual maintenance.
What You Should Know About Stopping Duloxetine
As stated above: due to the hyperbolic effect of the drug, the lower doses can cause the worst withdrawal symptoms. At low doses, even a tiny reduction causes a large change in how your brain reacts.
This is why:
- 20mg of duloxetine produces about 70% of the drug’s effect.
- 60mg produces about 80-85% of the drug’s effect.
- From 60mg and up, there is minimal increase in the drug’s effect.
- Going from 20mg to 120mg is a 6-times higher dose, but it only adds about 15% more serotonin occupancy.
- Reductions at lower doses can be harder. A decrease from 10mg to 5mg can cause a much bigger change in the brain than people expect.

What Works: The Hyperbolic Taper
A hyperbolic taper means making dose reductions that gradually decrease with each step.
In the Cymbalta Hurts Worse peer support group, we recommend a 5% or less reduction from the previous dose–not the original dose. Years of lived experience has shown that higher percentage reductions are often too large and can trigger withdrawal symptoms for many people.
The hyperbolic taper that we suggest is a slow, steady reduction based on a simple rule: reduce by no more than 5% of your current dose every two weeks or longer. Not 5% of your starting dose–your current dose.
Each step gets smaller as you reduce, and that is on purpose. It allows your brain to adjust slowly to each lower dose.
A complete taper from 60mg typically takes 2 to 4+ years. That is not a mistake. This is what works for MOST people. There are a rare few people who MAY be able to taper faster.
You need a taper plan, but you also need to stay flexible. Your body may not follow the schedule exactly, and you may need to slow down, hold at one dose for a while, or adjust your dose as you go.
Listen to your body!
We have free calculators that build your entire schedule for you. Use the Weighing or Counting method to measure your doses at home with a US$30 jewelry scale. Full instructions are on these pages.

Already Stopped and Struggling?
If you stopped too fast, went cold turkey, or made reductions that were too large, you are not broken. What you are feeling is real. It is not a weakness, and it may not be relapse. It can happen when an antidepressant drug is removed too quickly from a brain and body that have adapted to it.
There are options, including reinstatement at a lower dose if you stopped recently. Go to: stopped-and-struggling
⚠ If You Are in Crisis Right Now If you are having thoughts of harming yourself, call or text 988 (US Suicide & Crisis Lifeline) or go to your nearest emergency room. Severe withdrawal from duloxetine can cause temporary suicidal thoughts. This is a known, documented side effect. It does not mean you will always feel this way. |

FACEBOOK Group Update
Our original Facebook Group “Cymbalta Hurts Worse/duloxetine” was suspended in February 2026 by Facebook. You can now find us at Cymbalta Hurts Worse (duloxetine) 2.0 on Facebook.

We built a new home on Reddit.com for tapering advice. It’s called r/CymbaltaHurtsWorse.
Same people. Same rules. Same peer support that has helped 45,000 of us taper off duloxetine. Different platform.
This is a peer support community. We share what worked for us and what deprescribing specialists have learned. We do not give medical advice.
