Stopping antidepressants: discontinuation symptoms and why it needs medical supervision

Can you stop taking antidepressants?

Yes, stopping antidepressants is possible when the time is right. But the UK's National Health Service (NHS) clearly advises not to stop suddenly or without talking to your doctor first, because quitting abruptly can cause what are known as discontinuation or withdrawal symptoms. The safe way is to agree a plan with your doctor to reduce the medicine gradually over weeks or months, keeping an eye on how you feel at each step.

The NHS adds that it is common to keep taking the medicine for at least six months after your symptoms improve, to lower the chance of depression coming back. So the important question is not only "Can I stop?" but also "Is this the right time?" and "How do we stop safely?"

Why do you want to stop? When the reason calls for a review, not quitting

Wanting to come off medication is understandable, and there are many reasons for it. Some mean it really is time to plan stopping. Others mean the treatment plan needs adjusting, not that you should drop it on your own:

• You feel better and think you no longer need it: a good reason to talk to your doctor, but the improvement itself may be thanks to the medicine, and stopping too early raises the risk of symptoms returning.
• Troublesome side effects: such as weight gain, sleep problems or low sex drive. The NHS advises telling your doctor, as there may be other options, such as adjusting the plan or switching medicine. Read about antidepressant side effects and what can be done about them.
• You feel the medicine isn't helping: this calls for a review of the diagnosis and treatment, not stopping suddenly.
• Fear of "getting hooked" or what people say: many people worry the medicine is addictive. This is a common misunderstanding, which we explain in Are antidepressants addictive?.
• Planning a pregnancy, a physical illness or new medicines: these are situations where your doctor decides what is best for you and your health. If you find out you are pregnant, don't stop the medicine suddenly yourself; contact your doctor soon so they can weigh the benefits and risks with you, and read about antidepressants during pregnancy and breastfeeding.

What are the symptoms of stopping antidepressants suddenly?

When you take an antidepressant for a long time, your body and brain adapt to it. If its level drops suddenly, physical and emotional symptoms can appear. The NHS, Cleveland Clinic and the UK's Royal College of Psychiatrists describe the most common ones:

• Dizziness and unsteadiness: the most common symptom according to a recent scientific review, sometimes with a light-headed feeling
• Flu-like symptoms: tiredness, headache, aching muscles and joints, and sweating
• Nausea, sometimes with vomiting or an upset stomach
• Sensations like electric shocks or zaps in the head, often called "brain zaps", sometimes with numbness or tingling
• Sleep problems: insomnia, very vivid dreams or nightmares
• Mood changes: anxiety, irritability, agitation, rapid mood swings or low mood
• A racing heart, confusion and trouble concentrating, or a feeling that things aren't real

Not everyone who stops has these symptoms, and how strong they are varies a lot from person to person. The Royal College of Psychiatrists notes that the risk is higher with high doses, long-term use, fast reduction, and with some medicines more than others, especially those that leave the body quickly.

How long does antidepressant discontinuation syndrome last, and why isn't it addiction?

Symptoms usually start within a few days of stopping or lowering the dose; Cleveland Clinic says they often appear within two to four days. According to the NHS, for most people they last a few weeks, but some people have more severe or longer-lasting symptoms that can go on for months or more, which is more likely after long-term use or high doses. It is not yet possible to predict exactly who will have long-lasting symptoms.

Estimates of how common these symptoms are differ between studies. In 2024 the Royal College of Psychiatrists estimated that between a third and a half of people taking antidepressants experience them to some degree. A systematic review published in JAMA Psychiatry in 2025 covered 50 studies with about 18,000 participants. In the studies that measured symptoms with a dedicated scale, people who stopped had, on average, about one more discontinuation symptom in the first week than those who continued their medicine or stopped a placebo. This average difference was below the threshold used for a clinically important syndrome, and dizziness was the most common symptom. These differing estimates mean your experience may be very mild or quite unpleasant, and follow-up with your doctor is what decides the next step.

Most importantly, these symptoms are not addiction. As the Royal College of Psychiatrists explains, the difficulty in stopping comes from physical dependence, meaning the body has adapted to the medicine. Addiction means craving, loss of control and seeking a high, which antidepressants do not cause.

Does depression come back after stopping? How to tell the difference

Depression can return after stopping, especially if you stop early. A scientific review published in Molecular Psychiatry in 2024 summarizes that continuing antidepressants after improvement roughly halves the risk of relapse compared with placebo, from about 40% to about 20%. The researchers caution that most of these studies were fairly short and often stopped the medicine quickly. That is why the decision to stop needs careful timing; read more in How long does depression recovery take?.

But not everything you feel after stopping is the illness coming back. These differences, explained by the Royal College of Psychiatrists, help you and your doctor tell them apart:

• Timing: discontinuation symptoms begin within days of lowering or stopping, sometimes even after a single missed dose. Depression or anxiety returning usually comes on slowly, weeks or months later.
• Type of symptoms: discontinuation symptoms often include new sensations you never had with the depression itself, such as dizziness, electric-shock sensations and flu-like symptoms.
• Response to the medicine: discontinuation symptoms usually improve within hours or days if the doctor restarts the medicine, while relapse does not improve that quickly.

The 2025 JAMA Psychiatry review found that low mood was not linked to stopping itself in the studies it included, so sadness and loss of enjoyment that appear weeks later deserve an assessment for possible relapse. Don't try to judge this alone; describe to your doctor what you feel and when it started.

How to stop antidepressants safely: why the doctor plans and monitors the reduction

The NHS and the Royal College of Psychiatrists agree that stopping is best done gradually over weeks or months. But there is no single plan that suits everyone, which is why we give no schedules or amounts here. Your doctor builds the plan around:

• The type of medicine, since some leave the body faster than others
• How long you have taken it and your current dose
• Your past experiences with stopping, and whether you had symptoms before
• How you are now, your life circumstances, and the risk of the illness returning

During the reduction your doctor watches two things together: discontinuation symptoms and any signs of depression returning. If troublesome symptoms appear, the NHS says they may decide to slow the reduction or go back to a previous dose before you try again. The Royal College of Psychiatrists warns that skipping doses on some days instead of an organized reduction makes the medicine level go up and down and makes symptoms more likely, so don't adjust doses or split tablets yourself.

What to do if symptoms appear after a missed dose

You may feel dizzy, irritable or have mild zaps a day or two after missing your medicine. This is well known, and it is usually a sign that your body has noticed the drop in the medicine's level, not that your condition has worsened.

1. Don't make up for it yourself: don't double the next dose or change how you take the medicine without asking.
2. Check the instructions: read the leaflet that comes with the medicine, or ask your pharmacist or doctor what to do about the missed dose.
3. Go back to your usual routine as your doctor prescribed: Cleveland Clinic notes that returning to the prescribed dose usually eases the symptoms within about a day.
4. Tell your doctor if you keep forgetting or the symptoms are severe; they may suggest ways to remember or review the plan.

How to raise stopping with your doctor at your next appointment

Some people feel embarrassed to tell their doctor "I want to stop", so they stop in secret. In fact it is a normal question and you have every right to ask it. As the US National Institute of Mental Health (NIMH) explains, your doctor can adjust the treatment plan to reduce the medicine slowly and safely. These steps can help:

• Say it clearly at the start: "I'm thinking about stopping my medicine, and I'd like us to plan it together."
• Give your real reason: side effects, feeling better, worry about staying on it, or new circumstances.
• Share your past experiences: have you missed doses before and felt symptoms? Have you tried stopping before?
• Ask specific questions: Is this a good time? What symptoms should I expect? How do I tell them from relapse? When should I call you?
• Agree on follow-up: review appointments during the reduction, and a way to get in touch if troublesome symptoms appear.

Your doctor may suggest pairing the reduction with therapy sessions that help you build skills for coping with stress and spotting early signs of relapse.

When to get help straight away, and how we can help

Contact your doctor as soon as you can if:

• Discontinuation symptoms are severe and disrupt your work, studies or sleep
• Symptoms last more than a few weeks or are getting worse
• Sadness, loss of enjoyment and tiredness come back weeks after stopping
• You stopped suddenly and don't know what is happening to you; ask your doctor whether to go back on the medicine and at what dose, rather than restarting or changing it yourself

At Oxygen Center you can book an outpatient doctor appointment to review your medicine and a plan for stopping with the doctor. The service is open to men and women aged 15 and over (under 18 with a guardian's consent). The doctor starts by listening to your reasons and your history with the medicine, then builds a reduction plan that suits you with follow-up appointments, which can be combined with therapy sessions. Stopping medication safely is a normal step on the road to recovery, and you don't have to take it alone.
