What to expect when discontinuing citalopram

Stopping citalopram is not the same as stopping most other medications. Because citalopram is a selective serotonin reuptake inhibitor (SSRI), your brain has adapted to the drug's presence over weeks or months. Stopping abruptly can trigger withdrawal symptoms—sometimes called discontinuation syndrome—that feel like anxiety, dizziness, electric shock sensations, mood swings, or flu-like symptoms. These are not signs the medication was harming you; they are signs your nervous system is recalibrating.

The timeline and intensity depend on how long you took citalopram, what dose you were on, and how quickly you stopped. Most people who taper gradually over weeks experience mild or no withdrawal. People who stop suddenly, or who stop a high dose abruptly, are more likely to have noticeable symptoms that last days to weeks.

The actual benefits of stopping—reduced side effects, clearer thinking, weight loss, or restored sexual function—typically emerge after the withdrawal period ends, usually within two to four weeks. But the withdrawal phase comes first, and mistaking it for relapse of the original condition is common and often leads people to restart the medication unnecessarily.

Key Takeaways

  • Stopping citalopram suddenly can cause withdrawal symptoms like dizziness, mood changes, and electric shock sensations, even though the medication was working.
  • Tapering the dose gradually over weeks—usually under medical guidance—reduces or prevents withdrawal symptoms.
  • Benefits like reduced side effects or weight loss appear after the withdrawal phase ends, not when ready.
  • Withdrawal symptoms are not the same as relapse of depression or anxiety, though they can feel similar.
  • Your prescriber can provide a tapering schedule and help you distinguish withdrawal from a return of your original condition.

Why withdrawal happens when you stop citalopram

Citalopram works by blocking the reabsorption of serotonin in your brain, which increases the amount available in the spaces between nerve cells. After weeks on the drug, your brain adjusts: it may produce less serotonin naturally, reduce the number of serotonin receptors, or change how it regulates the system overall. When you remove the drug, serotonin levels drop suddenly, and your brain needs time to recalibrate.

This is not addiction in the traditional sense—citalopram does not create cravings or compulsive use—but it is a real physical dependence. Your nervous system has changed in response to the drug, and it cannot snap back to baseline overnight. The longer you took citalopram and the higher your dose, the more your brain has adapted, and the more time it typically needs to readjust.

Some people experience almost no withdrawal; others have weeks of noticeable symptoms. This variation is normal and does not reflect weakness or a problem with how you are stopping. Genetics, brain chemistry, the specific dose, and the speed of tapering all play a role.

Common withdrawal symptoms and how long they last

The most frequently reported symptoms are dizziness or vertigo, electric shock sensations (sometimes called "brain zaps"), anxiety, irritability, mood swings, insomnia, vivid dreams, and flu-like aches. Some people also report nausea, sweating, or a sensation of unreality. Symptoms usually begin within one to three days of a missed dose or a significant reduction and peak around day three to five.

For most people who taper gradually, symptoms are mild—a slight dizziness in the morning, occasional mood dips, or sleep disruption for a few nights. For people who stop suddenly or who were on high doses, symptoms can be more intense and last two to four weeks. A very small number of people report symptoms lasting longer, though this is uncommon.

The good news is that withdrawal symptoms are not dangerous, even though they feel uncomfortable. They do not cause permanent damage and they resolve on their own as your brain chemistry restabilizes. Knowing this in advance helps you avoid the trap of restarting the medication because you think something is wrong.

How to minimize withdrawal when stopping citalopram

The single most effective strategy is to taper the dose slowly rather than stop all at once. A typical taper reduces the dose by 10 percent every one to two weeks. For example, if you are on 20 mg daily, you might drop to 18 mg for one to two weeks, then 16 mg, then 14 mg, and so on. Some people taper even more slowly, especially if they were on high doses or experienced withdrawal symptoms during previous attempts.

Your prescriber can provide a specific tapering schedule based on your dose and history. If your current prescriber is unwilling or unavailable, a pharmacist can often help design a taper, and some psychiatrists specialize in medication discontinuation and can take over your care for this purpose.

During the taper, keep a straightforward log of any symptoms you notice—mood, sleep, physical sensations—so you can report them to your prescriber. If withdrawal symptoms become severe, your prescriber can slow the taper further. There is no prize for speed; a slower taper that keeps you comfortable is always the better choice.

Side effects that may improve after stopping

Many people take citalopram for years without bothersome side effects, but others experience weight gain, sexual dysfunction, emotional blunting, fatigue, or tremors. These side effects do not happen to everyone, and they do not mean the medication is wrong for you—but if they are affecting your quality of life, stopping may reverse them.

Weight gain often begins to reverse within weeks of stopping, though the timeline varies. Sexual dysfunction typically improves within days to weeks. Emotional blunting—the sense that you feel less joy or sadness, that life feels muted—often lifts within one to two weeks. Fatigue and tremors usually improve similarly.

The catch is that these improvements come after the withdrawal phase. During the first week or two, you may feel worse before you feel better. Knowing this helps you push through the temporary discomfort without assuming you made a mistake.

When stopping citalopram is not the right choice

If you are stopping because your depression or anxiety has improved and you want to see if you can manage without medication, that is a reasonable conversation to have with your prescriber. If you are stopping because of side effects, there are often alternatives—different SSRIs, different classes of antidepressants, or dose adjustments that might help.

If you are stopping because you believe the medication is harming you or because you have read that SSRIs are dangerous, talk to your prescriber before you stop. Some concerns about SSRIs are overstated, and some are real but manageable. Your prescriber can help you weigh the actual risks and benefits in your specific situation.

Stopping abruptly because you ran out of medication or because you are angry at your prescriber usually leads to unnecessary withdrawal symptoms and sometimes to a crisis that lands you back on the medication at a higher dose. If you are frustrated with your treatment, that is worth addressing directly with your prescriber or by finding a new one—but stopping without a plan rarely improves the situation.

What to do if withdrawal symptoms are severe

If you are experiencing intense withdrawal symptoms, contact your prescriber. Do not assume you need to restart the full dose; instead, your prescriber can have you take a small dose to ease the symptoms, then taper more slowly from there. This approach—sometimes called "micro-tapering"—can make the process much more tolerable.

Some prescribers are unfamiliar with discontinuation syndrome and may dismiss your symptoms or tell you to just push through. If that happens, you can ask for a referral to a psychiatrist who specializes in medication tapering, or you can consult a pharmacist at your local pharmacy who can advise on tapering strategies.

In the meantime, basic self-care helps: staying hydrated, eating regular meals, getting sleep when you can, and avoiding major life stressors during the taper. Some people find that gentle exercise, time in daylight, or talking to a therapist helps them tolerate the temporary discomfort.

Frequently Asked Questions

Can I stop citalopram cold turkey?

Technically yes, but most people experience withdrawal symptoms if they do. A gradual taper over weeks is far more comfortable and is the standard recommendation. If you have already stopped suddenly, the symptoms will pass on their own, usually within two to four weeks.

How long does it take to taper off citalopram?

A typical taper takes four to eight weeks, depending on your dose and how slowly you reduce it. Some people taper faster; others go slower to minimize symptoms. Your prescriber can give you a specific timeline based on your situation.

Will I relapse into depression or anxiety after stopping citalopram?

Some people do, and some do not. The risk is higher if you stop soon after starting the medication or if you had severe depression or anxiety before. Withdrawal symptoms can feel like relapse, which is why keeping a symptom log and staying in touch with your prescriber during the taper is important.

What if I want to switch to a different antidepressant instead of stopping completely?

Your prescriber can cross-taper you—gradually reducing citalopram while starting the new medication—so you avoid a gap where you are on nothing. This is often easier than stopping completely and then restarting something else later.

Is it safe to stop citalopram if I am pregnant or breastfeeding?

This requires a conversation with your prescriber and your obstetrician, because the risks of untreated depression during pregnancy and the risks of the medication itself both matter. Some people stay on citalopram through pregnancy; others taper or switch. The decision depends on your individual circumstances.
