Stopping antidepressants: recognizing and tracking withdrawal symptoms

Brain zaps, dizziness, flu-like feelings — reducing or stopping an antidepressant can cause very real withdrawal symptoms. Here's how to recognize them, tell them apart from a relapse, and track them day by day to adjust the taper with your doctor.

Information, not medical advice. This page helps patients observe and communicate what they feel. It offers no tapering protocol and does not replace a consultation, medical advice, or your medication's patient leaflet. Never stop an antidepressant abruptly: any reduction is decided and planned with your doctor. If you have suicidal thoughts, contact a crisis line — 988 (US), 116 123 (Samaritans, UK & Ireland) — or your local emergency number (112 in Europe).

The withdrawal syndrome is real — and it isn't a relapse

When you reduce or stop an antidepressant, your body has adapted to the molecule. Lowering it too fast can trigger a discontinuation (withdrawal) syndrome. It is neither a sign of weakness nor proof that you "still need" the medication: it's a temporary physiological reaction.

Telling it apart from a relapse is essential, because the two call for different responses. Confusing one for the other can lead to restarting a treatment you could have come off — or, conversely, blaming withdrawal for symptoms that deserved attention.

More likely withdrawal

  • Appears fast: 1 to 3 days after the reduction
  • Unusual physical symptoms (zaps, dizziness)
  • Fades within a few days to weeks
  • Often relieved by slowing the taper

More likely relapse

  • Returns gradually, more often after 2 to 4 weeks
  • Reproduces your original symptoms (low mood, loss of drive)
  • Settles in and persists instead of easing
  • Few "electric-shock" physical symptoms
Withdrawal symptoms Relapse
Withdrawal or relapse? The two don't follow the same curve: withdrawal rises fast after the reduction then fades, while a relapse returns later and settles in. It's this curve, tracked day by day, that helps your doctor decide.

The most common withdrawal symptoms

They mostly affect short half-life antidepressants — paroxetine (Paxil, Seroxat) and venlafaxine (Effexor) above all. Fluoxetine (Prozac), with a long half-life, rarely causes them.

Electric shocks ("brain zaps") Brief sensations in the head, sometimes on eye movement
Dizziness, imbalance Head spinning, the ground seems to move
Flu-like feelings Fatigue, aches, chills, sweating
Nausea Upset stomach, especially the first few days
Sleep disturbances Insomnia, very vivid dreams, nightmares
Emotional lability Irritability, anxiety, tearfulness, mood swings

The mnemonic FINISH sums them up: Flu-like, Insomnia, Nausea, Imbalance, Sensory disturbances (zaps), Hyperarousal (anxiety, irritability).

When do they appear, and how long do they last?

Withdrawal symptoms usually begin 1 to 3 days after a dose reduction or stop. Their duration varies: a few days to a few weeks for most people, sometimes longer. The rule that changes everything: the more gradual the reduction, the gentler the withdrawal. That pace of reduction is exactly what you adjust with your doctor — and precise notes make it possible.

Why track it day by day

During a taper, memory is a poor guide: at the appointment, you no longer know whether the dizziness started on day 2 or day 6, or whether it's getting worse or easing. Yet that curve is exactly what tells your doctor whether to slow down, hold the level, or continue.

In PsychoDose, you log your energy, sleep, mood and symptoms each day in 90 sec — with the date of every dose change. After two weeks, you have a clear curve: "the zaps started 2 days after dropping to 10 mg, peaked on day 5, now fading." A doctor can decide with that.

The signals that mean call your doctor

Most withdrawal symptoms are unpleasant but not dangerous. Some require prompt contact:

If you have suicidal thoughts, contact a crisis line — 988 (US), 116 123 (Samaritans, UK & Ireland) — or your local emergency number.

Talking to your doctor about the reduction

Arriving with dated notes transforms the consultation. Instead of "I had ups and downs," you can say: "since dropping to 37.5 mg on the 12th, I've had brain zaps every morning, worse on days I sleep badly, and irritability 5 days out of 7." With that level of detail, your doctor can adjust the pace instead of saying "let's see next month."

Reducing or stopping a treatment? Track what you feel every day. 90 sec is enough.
