When you stop taking an antidepressant, you may have withdrawal symptoms, a return of the condition it was treating, both, or neither. Some people feel no change. Others develop symptoms within days of reducing a dose or stopping, especially if they stop suddenly or miss doses.

The safest approach is to talk with your prescriber before making a change and agree on a gradual plan. There isn’t one taper schedule that suits everyone: the right pace depends on the medication, how long you’ve taken it, your response to dose reductions, and your circumstances. NICE guidance on stopping antidepressants recommends reducing the dose in stages and monitoring for both withdrawal symptoms and a return of depression.

Possible symptoms after stopping an antidepressant

Withdrawal symptoms—also called discontinuation symptoms—can affect your body, mood, sleep, or concentration. They may include:

Dizziness or feeling unsteady
Nausea, headaches, muscle aches, or sweating
Fatigue or difficulty concentrating
Sleep disruption or vivid dreams
Anxiety, irritability, tearfulness, or low mood
Unusual electric-shock sensations, often called “brain zaps”

Not everyone experiences these symptoms, and the type and intensity vary. Low mood or anxiety can occur during withdrawal, so feeling this way after a dose reduction doesn’t automatically mean the original condition has returned. The NHS overview of antidepressants and NICE guidance describe these and other possible symptoms.

Symptoms can follow an abrupt stop, but they can also happen after missed doses or a reduction that was larger or faster than your body tolerates. This is one reason not to skip doses to “test” how you feel.

When symptoms may start—and how long they may last

Withdrawal symptoms often begin within a few days of reducing or stopping an antidepressant. NICE says they commonly settle within one to two weeks, but they can sometimes last several weeks or, occasionally, months. These are general patterns, not a guaranteed timeline: some people have milder symptoms, while others need a longer, more gradual taper. (NICE recommendations; NICE patient guidance)

The timing can offer a clue, but it can’t tell you the cause by itself. If symptoms are severe, aren’t improving, or are getting worse, contact your prescriber or doctor rather than waiting for a set number of days to pass. The NHS advises seeking medical review when depression symptoms don’t improve or worsen.

Withdrawal or a return of depression?

It can be difficult to tell the difference because withdrawal and depression can share symptoms, including low mood, anxiety, and sleep problems. Both can also happen around the same time.

Timing and the kind of symptoms you have can help your prescriber assess what’s going on. Withdrawal often starts soon after a dose reduction or stop. NICE notes that a return of depression does not usually happen as soon as the dose is lowered. Physical or sensory symptoms—such as nausea, dizziness, or brain zaps—may also point toward withdrawal, particularly if they weren’t part of your original condition. But these patterns aren’t proof, and symptoms alone can’t confirm the cause. (NICE guidance; NHS antidepressant information)

A prescriber can consider when symptoms began, what changed in your dose, your past symptoms, and how you’ve responded to treatment. They can also help decide whether to pause a reduction, adjust the taper, or monitor for signs that the original condition is returning. Don’t assume that every difficult feeling is withdrawal—or that it must mean treatment is needed again—without considering the full picture.

How to stop more safely

If you’re considering stopping, start by speaking with the person who prescribes your medication. You can discuss why you want to stop, what symptoms to watch for, and how to contact them if a reduction feels difficult. NICE recommends agreeing the plan with the person taking the antidepressant and monitoring both withdrawal symptoms and the return of depression symptoms. (NICE recommendations; NICE quality statement)

In general, a safer plan involves:

Reducing the dose in stages. NICE recommends stepwise reductions rather than an abrupt stop. Reductions may need to become smaller as the dose gets lower.
Adjusting the pace to your response. Some people can reduce more quickly than others. Your prescriber can take into account the medication, how long you’ve taken it, and any symptoms that follow a reduction. For some people, tapering may take weeks or months.
Waiting before the next reduction if symptoms are difficult. NICE advises waiting until withdrawal symptoms have resolved or become tolerable before making another reduction. If symptoms are significant, contact your prescriber; they may consider a slower taper.
Asking about practical ways to make smaller reductions. If your tablets or capsules don’t allow the dose changes in your plan, ask whether a liquid form is available and appropriate. NICE notes that liquid preparations may help when very small reductions can’t be made with solid forms.

These are planning principles, not a personal dose schedule. Don’t copy a timetable or percentage reduction you’ve seen elsewhere: the guidance does not set one schedule for everyone. If withdrawal symptoms are more severe, NICE says a prescriber may consider returning to the previous dose and reducing more gradually. Don’t restart or change your dose on your own; discuss what to do with your prescriber. (NICE recommendations)

If you’re thinking about stopping because of serious or intolerable side effects, contact your prescriber promptly to discuss the safest next step. The usual pace may not fit every situation; NICE notes that the wider clinical circumstances can justify a more rapid withdrawal.

Common mistakes to avoid

Stopping suddenly. An abrupt stop can trigger withdrawal symptoms. If you’ve already stopped, tell your prescriber when you last took a dose and what you’re experiencing. They can help decide what to do next.

Skipping doses to make the taper easier. Missed doses can also lead to symptoms. Ask your prescriber or pharmacist about an appropriate way to reduce your specific medication rather than creating gaps between doses.

Pushing through significant symptoms to keep to a timetable. If symptoms become hard to manage, contact your prescriber before making another reduction. NICE’s guidance is to wait until symptoms have resolved or become tolerable before moving to the next step.

Expecting an exact timeline. Many people’s symptoms settle within one to two weeks, but some last longer. A timeline that was manageable for someone else may not be right for you.

Treating every mood change as either withdrawal or relapse. The two can overlap, and timing isn’t enough to settle the question. Share the sequence of dose changes and symptoms with your prescriber, including any physical or sensory effects.

When to seek help

Contact your prescriber or doctor if symptoms are severe, worsening, persistent, or difficult to manage. Seek urgent local help if you have suicidal thoughts or an immediate concern about your safety. Suicidal feelings and low mood can occur during discontinuation, but they shouldn’t be ignored. (NHS antidepressant information)

If you’re planning to stop, the useful next step is to make an appointment or contact your prescriber before changing your dose. Bring the name and dose of your medication, how long you’ve taken it, and any symptoms you’ve noticed after missed or reduced doses. That information can help you agree on a plan that responds to your needs rather than relying on a one-size-fits-all timetable.

FAQ

What happens if you stop an antidepressant suddenly?

An abrupt stop can trigger withdrawal symptoms. Symptoms can also happen after missed doses or a dose reduction that was larger or faster than your body tolerates. Contact your prescriber for help deciding what to do next.

How long do antidepressant withdrawal symptoms last?

Withdrawal symptoms often begin within a few days and commonly settle within one to two weeks. They can sometimes last several weeks or, occasionally, months. These are general patterns, not a guaranteed timeline.

How can you tell withdrawal from returning depression?

Timing and symptoms can offer clues, but they can’t confirm the cause on their own. Withdrawal often starts soon after a dose reduction or stop, and physical or sensory symptoms may point toward withdrawal. A prescriber can consider your dose changes, symptom history, and treatment response.
