Coming Off Antidepressants.
How to Taper Safely and What to Expect.

At some point, many people on antidepressants start thinking about stopping. Maybe you have felt well for a long time. Maybe the side effects are bothering you. Maybe you just want to know if you still need the medication. These are reasonable questions -- but how you stop matters as much as whether you stop.

What Is Discontinuation Syndrome?

When you stop an antidepressant -- especially abruptly -- your brain has to re-adjust to functioning without the medication. This adjustment can produce a cluster of symptoms that are often described using the acronym FINISH:

• F -- Flu-like symptoms (achiness, sweating, chills)
• I -- Insomnia (often with vivid dreams)
• N -- Nausea
• I -- Imbalance (dizziness, lightheadedness)
• S -- Sensory disturbances (the most distinctive: "brain zaps" -- brief electrical shock sensations, usually in the head; also visual flashes, tingling)
• H -- Hyperarousal (anxiety, irritability, agitation)

Discontinuation syndrome is not dangerous in the way that alcohol or benzodiazepine withdrawal can be -- it will not cause seizures or be life-threatening. But it can be extremely unpleasant and disruptive, and it is almost entirely preventable with a proper taper.

Discontinuation symptoms typically begin within 2 to 4 days of stopping and resolve within 1 to 2 weeks. With a gradual taper, symptoms are usually minimal or absent.

Which Antidepressants Are Most Likely to Cause Discontinuation Symptoms?

The risk is related to the medication's half-life -- how long it stays in the body after you stop taking it.

• Higher risk: Paroxetine (Paxil) and venlafaxine (Effexor) have short half-lives and are associated with the most significant discontinuation symptoms. Brain zaps and intense rebound anxiety are common.
• Moderate risk: Sertraline (Zoloft), escitalopram (Lexapro), citalopram (Celexa), duloxetine (Cymbalta).
• Lower risk: Fluoxetine (Prozac) has a very long half-life and essentially self-tapers -- discontinuation symptoms are rare and mild. This long half-life is sometimes used clinically: switching a patient to a brief course of fluoxetine before discontinuing can ease the transition off a shorter-acting medication.

How Does Tapering Work?

A taper is a gradual, stepwise reduction in dose over time, allowing your brain to adjust incrementally rather than abruptly. The general principles:

• Slow is better. A commonly cited guideline is reducing by no more than 10 to 25 percent of the current dose every 2 to 4 weeks. For some people -- particularly those on higher doses or longer courses -- an even slower taper is appropriate.
• The last steps are often the hardest. Going from 20 mg to 10 mg tends to be easier than going from 5 mg to zero. This is because of how serotonin receptor occupancy works -- small reductions at the lower end represent larger proportional changes at the receptor level. Many providers use very small final doses (sometimes liquid formulations or pill splitting) to manage this.
• Monitor for both discontinuation symptoms and relapse. The tricky part is distinguishing between "my brain is adjusting to less medication" (temporary, expected) and "my depression or anxiety is returning" (a signal to slow or stop the taper). Your provider will help you watch for these different patterns.
• Duration varies. For most people, a taper over 4 to 8 weeks is sufficient. For people who have been on higher doses for longer periods, or who are more sensitive, several months may be appropriate.

When Does It Make Sense to Stop?

Stopping antidepressants is not always the right goal. The right answer depends on your history:

• First episode of depression or anxiety, fully resolved: Current guidelines generally recommend continuing medication for 6 to 12 months after full symptom remission before considering a taper. Stopping before that significantly increases relapse risk.
• Two or more episodes: The risk of another episode is higher, and many providers recommend longer-term maintenance therapy -- often 2 or more years, or indefinitely, depending on severity.
• Ongoing symptoms: If your symptoms are still present, stopping medication will almost certainly make things worse. The goal is full remission before tapering begins.
• Situational factors: Timing matters. Tapering during a period of major stress (a job change, a relationship ending, a health scare) is not ideal. When your life is stable, your brain has more capacity to handle the adjustment.

What If Symptoms Come Back During the Taper?

If symptoms return -- either discontinuation symptoms that are significantly impairing, or signs that your underlying condition is re-emerging -- the taper can be slowed, paused, or reversed. Going back up to a previously effective dose is not a failure. It is data. It tells you something important about whether this is the right time to taper, or whether the medication is still doing meaningful work.

The decision to stop, continue, or adjust is an ongoing clinical conversation -- not a one-time choice. The right plan is whatever supports your long-term wellbeing, not what meets an arbitrary timeline.
