Key takeaways 1 in 3 people describing antidepressant withdrawal (32%) had signs of severe withdrawal: they called it severe, went back on the drug because of it, or could not work. About 1 in 4 (27%) called it severe in their own words. Half of those who said how long it lasted (50%) had symptoms past two weeks, the time NICE gives for mild symptoms. Nearly 1 in 5 (18%) were still in withdrawal past three months, and 1 in 10 past six months. 4 in 5 who mentioned a warning (80%) say their doctor gave none, or said there would be no withdrawal. More than half who described their doctor's instructions (54%) say they were told to stop at once or within two weeks. On this page
1 in 3 People Describing Withdrawal Had Signs of Severe Withdrawal How Long Withdrawal Lasted: Half Were Still in It After Two Weeks What People Say Their Doctor Told Them About Withdrawal What Withdrawal Is, and How It Differs From Depression Coming Back What This Shows What to Do With This How We Did This UK guidance says mild withdrawal symptoms usually pass within one to two weeks, and that withdrawal can sometimes be severe or last several weeks, occasionally months. This report looks at how people describe it in their own words. We read public Reddit posts from 5,545 people on antidepressants, written from January 2024 to October 2026. Among 566 who described their own withdrawal, 1 in 3 (32%) had signs of severe withdrawal, and about 1 in 4 (27%) called it severe.
What we found. People who post about withdrawal often describe the longer, harder course that guidance calls less common. Most of those who mention their doctor say no one prepared them for it. The problem they describe starts before stopping, in the conversation with their doctor.
About this report. This is a social listening analysis of public Reddit posts. It is not a clinical study. The figures come from what people chose to share, and they are self-reports. Clinical trials assess symptoms with rating scales and follow people over time. We counted what people said about their own experience. People with mild or no withdrawal are less likely to post about it, so the shares here are higher than they would be among everyone who takes an antidepressant. The figures do not show how common withdrawal is in general, and they are not medical advice.

1 in 3 People Describing Withdrawal Had Signs of Severe Withdrawal
We counted 566 people who described their own withdrawal symptoms. 182 of them (32%) showed at least one of three signs of severe withdrawal. 150 (27%) called it severe in their own words, 58 went back on the drug because of withdrawal, and 20 could not work. Some people showed more than one sign.
Earlier online surveys found higher shares. In a 2019 review, 46% of people with withdrawal gave it the most extreme severity rating. In a 2020 survey of 867 people, 44% of those with withdrawal called it severe.
Clinical trials count differently. In a 2024 review, 31% of people who stopped an antidepressant had at least one withdrawal symptom, against 17% who stopped a placebo, and about 3% had severe symptoms. A 2025 review of trials found that a week after stopping, people had on average about one more symptom than those who stopped a placebo. Most people in these trials had taken the drug for weeks or months, not years, and were followed for a short time. A 2025 reanalysis that kept only the trials which asked everyone about withdrawal put the share with symptoms at about half. Our figure counts only people who already had symptoms, so it measures something different.
The table puts what the official drug labels say next to what people in our data reported. The US drug labels list withdrawal symptoms for each drug, and NICE, the UK health guidance body, names two of them as more likely to cause withdrawal.
Drug What official sources say Signs of severe withdrawal Cymbalta (duloxetine) FDA: dizziness, headache, nausea, irritability, insomnia 38% of 118 Effexor (venlafaxine) NICE: higher risk. FDA: more likely at higher doses and after longer use; some people need several months to stop 41% of 116 Lexapro (escitalopram) FDA: dizziness, shock-like sensations, irritability, insomnia 33% of 125 Paxil (paroxetine) NICE: higher risk. FDA: nausea, dizziness, shock-like sensations, insomnia 37% of 121 Zoloft (sertraline) FDA: nausea, sweating, dizziness, shock-like sensations 28% of 78
The ranges for all five drugs overlap, so our column is not a ranking. This fits NICE guidance and trial reviews, which find withdrawal more likely with venlafaxine and paroxetine.
How Long Withdrawal Lasted: Half Were Still in It After Two Weeks
Of 310 people who said how long their withdrawal lasted, 154 (50%) had symptoms past two weeks. One in three (33%) were past a month. Nearly one in five (18%) were past three months, and one in 10 (10%) past six months. Each share is out of the people whose answer settles that point, so the totals differ a little. Someone who said "a few weeks" counts toward the one-month share but not the two-week one.
Withdrawal still going Share Chart Past 2 weeks 50% (154 of 310) Past 1 month 33% (103 of 313) Past 3 months 18% (55 of 301) Past 6 months 10% (29 of 298)
Some people were still in withdrawal when they posted, so these shares are a floor. NICE also notes that withdrawal can sometimes last several weeks and occasionally several months. A few people described withdrawal that lasted more than a year or left them barely able to leave home. These cases were rare in our data.
What People Say Their Doctor Told Them About Withdrawal
We found 105 people who said whether their doctor had warned them about withdrawal. Of those, 84 (80%) said no warning came. That includes 28 (27%) who said their doctor told them there would be no withdrawal at all.
We found 352 people who described what their doctor told them about stopping. Of those, 189 (54%) said they were told to stop at once or within two weeks. NICE recommends reducing the dose in steps and watching for symptoms after each one.
In a separate search of all 5,545 people, we found 23 who compared their withdrawal with what their doctor had said to expect. 21 of them said it lasted longer, or came when they had been told it would not.
What people said about their doctor Share Out of No warning, or told there would be no withdrawal 80% 105 who mentioned a warning Told there would be no withdrawal 27% 105 who mentioned a warning Told to stop at once or within two weeks 54% 352 who described instructions Withdrawal lasted longer than the doctor said 21 of 23 23 who compared
These are people's memories of what they were told. Some may have missed or forgotten a warning, and we didn't hear from the doctors. A 2020 survey across 31 countries found a similar pattern: of 867 people, fewer than 1% recalled their first prescriber telling them anything about withdrawal. An analysis of 158 personal accounts sent to the Scottish and Welsh parliaments found that a lack of information about withdrawal risk was one of the main problems people described.
What Withdrawal Is, and How It Differs From Depression Coming Back
Withdrawal is what the body goes through as it adjusts to a lower dose or no dose. For many people it is mild and passes within a couple of weeks. In our data, one in three people who gave a length were still in withdrawal after a month. When symptoms go on that long, they can be hard to tell apart from depression or anxiety coming back, and a prescriber can help work out which it is. In a UK trial of people who had been on antidepressants for a long time, 56% of those who stopped had their depression come back within a year, against 39% of those who stayed on, and those who stopped also reported more withdrawal symptoms.
Reducing an antidepressant gradually, in steps agreed with your prescriber, can lower the risk of withdrawal symptoms. For some people this takes weeks or months.
When a dose is cut or stopped, the brain has to adjust. That adjustment can cause withdrawal, also called discontinuation symptoms, such as dizziness, brain zaps (brief electric shock feelings), nausea, sweating, poor sleep, anxiety and irritability.
Withdrawal and a return of depression can feel alike. Telling them apart matters: withdrawal usually means slowing the reduction, while depression coming back may mean staying on or restarting treatment. Your prescriber can help you work out which it is.
Withdrawal tends to start within days of a cut and includes physical symptoms, like brain zaps. If your prescriber puts you back on your previous dose, it often eases within a few days. A relapse usually builds more slowly, over weeks. Symptoms you did not have when you were depressed, such as dizziness or brain zaps, point to withdrawal. The return of your old symptoms points to depression coming back.
If symptoms during a reduction are hard to bear, talk to your prescriber before changing your dose. They may suggest going back to the last dose that felt stable, then reducing more slowly, in smaller steps.
Before you stop, ask your prescriber what to expect, which symptoms to watch for and how the dose will come down in stages. More on this: a guide to tapering off antidepressants safely and how to prepare for a medication appointment .
This report describes what people say online. In the UK, the guidance to follow is NICE's. Elsewhere, ask your prescriber which guidance applies.
The report has limits:
People reported their own symptoms. We saw no diagnoses or medical records. People with a hard time are more likely to post, so severe and long withdrawal is overrepresented. From a post alone, withdrawal can't be told apart from depression coming back. Some people were still in withdrawal when they posted, so their withdrawal is counted only up to that day. We don't know where people live or which guidance their doctor followed. What This Shows
In what people wrote, withdrawal often ran past the one to two weeks that UK guidance gives for mild symptoms: half of those who gave a length were still in it after two weeks. Many went into it unprepared: 4 in 5 who mentioned a warning said they got none, or were told there would be no withdrawal. And more than half who described their doctor's instructions were told to stop at once or within two weeks, while NICE recommends reducing the dose in steps.
These findings are in line with NICE guidance, which already says withdrawal can sometimes be severe and occasionally last several months. The posts show how that harder course looks to the people going through it, and where they feel the conversation with their doctor fell short.
What to Do With This
If you plan to stop, ask your prescriber before you start:
How long can withdrawal last on my drug? What will the steps be? What do I do if symptoms come? If symptoms come during a reduction, write down when each one started and how it changed, so your prescriber can see the timeline. The withClaro app lets you log mood, sleep and side effects each day and bring that record to your appointment.

How We Did This
The team behind the withClaro app, built for people on antidepressants, read public Reddit posts and comments from January 2024 to October 2026. They came from nine communities: r/antidepressants, r/SSRIs, r/Effexor, r/cymbalta, r/lexapro, r/zoloft, r/bupropion, r/depression_help and r/Anxiety. That came to 9,289 threads and 98,408 comments. We counted people, not posts: 5,545 people who wrote about their own antidepressant use, each counted once.
Withdrawal figures come from a random sample of people found through searches for withdrawal and tapering. Figures about doctors come from a random sample of people who wrote about their doctor and withdrawal. We coded each person against a fixed codebook, and every label is backed by a quote from the person's own words. The posts of 1,147 people, including everyone with withdrawal, were coded a second time independently. We settled the 148 disagreements on withdrawal by going back to the quotes, and checked part of the coding against a hand-coded sample.
The figure for signs of severe withdrawal, 32%, has a 95% Wilson interval of 28.4% to 36.1% (182 of 566 people). People with a hard time are more likely to post about it. These figures describe what people report online, not everyone who takes an antidepressant.
Frequently asked questions How common is severe antidepressant withdrawal? In our data, 1 in 3 people who described withdrawal had signs of severe withdrawal, and about 1 in 4 called it severe. Clinical trials report lower rates. They count everyone who stopped, mostly after short-term use, and people with a hard time are more likely to post online. Ask your prescriber about your own risk before you lower your dose.
How long does antidepressant withdrawal last? UK guidance says mild symptoms usually pass within one to two weeks, though some people have them for weeks or months. Half of the people in our data who gave a length had symptoms for longer, and 1 in 10 past six months. Plan the reduction with your prescriber so you can slow down if symptoms come.
Do doctors warn patients about antidepressant withdrawal? Of the people who mentioned it, 4 in 5 said their doctor did not warn them. Ask about withdrawal when you start a new antidepressant, and again before you stop.
Which antidepressant has the worst withdrawal? Our data does not rank drugs: the ranges overlap. NICE names paroxetine and venlafaxine as more likely to cause withdrawal, and reviews of trials agree. They find less withdrawal with fluoxetine and sertraline. If you take one of them, plan the reduction with your prescriber well in advance.
