The Safest Way to Stop an Antidepressant

Stopping an antidepressant safely means stopping it gradually under prescriber guidance. The Royal College of Psychiatrists, NICE NG222, and Maudsley Prescribing Guidelines all recommend tapering rather than abrupt discontinuation, even when the patient feels well. Sudden stopping produces discontinuation symptoms that are often more difficult than tapering and can be confused with relapse.

Why tapering matters

When an antidepressant is stopped abruptly, neurotransmitter levels change rapidly, triggering discontinuation symptoms — brain zaps, dizziness, flu-like feelings, emotional volatility — the brain produces while adapting to the absence. Tapering — reducing the dose gradually over weeks or months — gives the brain time to adapt at each step, reducing or eliminating these symptoms for most patients.

What tapering typically involves

Tapering schedules vary by medication and individual. Maudsley Prescribing Guidelines recommend slower tapers than older guidelines suggested, particularly for short-half-life medications and for patients who have been on treatment for longer. A common pattern: reduce by 25 percent of the current dose, hold for two to four weeks while any symptoms settle, then reduce again. Tapering over months rather than weeks is often appropriate.

What to do during a taper

Keep a daily record. Track sleep, body, mood, and any unusual sensations across each dose reduction so you and your prescriber have a clear picture.

Report before each step. Tell your prescriber how each dose reduction goes before moving to the next. Do not assume the next reduction is safe without checking in.

Slow down, don't push through. If symptoms appear, pause the taper or return to the previous dose. The right response is slower, not toughing it out.

Do not skip steps or stop abruptly. Even if you feel well, sudden discontinuation can produce severe symptoms. Complete each step as planned.

What to flag to your prescriber

Contact your prescriber if you notice

Severe discontinuation symptoms not settling within two to four weeks.
Return of original depression or anxiety symptoms — this may indicate relapse rather than discontinuation.
New suicidal thoughts during the taper.
Any symptom severe enough to affect safety or function.

Frequently asked questions

Why can't I just stop my antidepressant?

Sudden stopping produces discontinuation symptoms for most patients — brain zaps, dizziness, flu-like feelings, emotional volatility. Tapering gives the brain time to adapt at each step, reducing or eliminating these symptoms.

How long should tapering take?

Varies by medication and how long you have been on it. Short courses may taper over weeks; long-term treatment may require months. Your prescriber will recommend a schedule based on your specific situation.

What if I get symptoms during the taper?

Pause the taper or return to the previous dose and contact your prescriber. The right approach is slower, not pushing through. Symptoms that appear during tapering are a signal that the current pace is too fast.
