@mmsm Here's the most recent study:

For someone who has taken Lexapro (escitalopram) 10 mg for 5 years, a taper of 5 mg for 7 days, then stop is often too fast and not considered best practice for many people.

Why this matters:

Lexapro is an SSRI with effects on brain serotonin receptors that adapt over time. After long-term use, stopping too quickly can trigger SSRI discontinuation syndrome, which is common, not rare.

Symptoms may include:

Anxiety, agitation, or panic.

Dizziness or “brain zaps”.

Palpitations.

Insomnia.

Flu-like symptoms.

Mood swings or depression relapse.

These symptoms can appear within days of stopping and are often mistaken for “anxiety returning” or heart issues.

Is 5 mg for 7 days → stop “standard”?

It is sometimes suggested by PCPs.

It is not the approach most psychiatrists or guidelines recommend after years of use.

It carries a higher risk of withdrawal, especially in sensitive individuals or those already experiencing palpitations.

What is generally considered safer:

Many experts recommend:

Slow, gradual tapering, often over weeks to months.

Reductions of 10–25% of the dose every 2–4 weeks.

Slowing further once below 5 mg, where withdrawal risk increases.

A common example (one of many possible approaches):

10 mg → 7.5 mg for several weeks.

7.5 mg → 5 mg for several weeks.

5 mg → 2.5 mg for several weeks.

Then stop.

(Some people go even slower.)

Important nuance in your case:

Since:

You’ve been on Lexapro 5 years>

You’re already experiencing palpitations.

A cardiologist advised stopping.

A slower taper is usually more, not less, heart-friendly because it avoids sudden nervous-system stress.

Key takeaways:

Withdrawal symptoms are real and well-documented*

Fast tapers increase the risk.

If symptoms appear, it does not mean you “need the drug again” — it may mean the taper was too quick.

A psychiatrist (or PCP comfortable with slow tapers) is often better suited to guide this.

Harvard Medical School explains that slow tapering over weeks to months helps minimize withdrawal symptoms.
It also notes rapid discontinuation (1–7 days) increases risk of relapse vs. gradual taper.

A systematic review found most major guidelines recommend gradual tapering for antidepressants, and withdrawal symptoms can be common after stopping long-term use.

5. SSRI tapering evidence (PubMed). Research shows tapering over months and reducing dose slowly (especially at low doses) leads to fewer withdrawal symptoms than abrupt stopping.

The UK Royal College states if you get withdrawal symptoms, you should slow down the taper — not stop abruptly. https://www.rcpsych.ac.uk/mental-health/treatments-and-wellbeing/stopping-antidepressants

7. Wikipedia (Escitalopram) — Withdrawal section
Summarizes evidence that abrupt stopping (especially after long-term use) is linked with withdrawal symptoms, and very slow tapering is recommended. https://en.wikipedia.org/wiki/Escitalopram

What these sources collectively show:

✔️ SSRIs like Lexapro can cause withdrawal symptoms if stopped too fast.
✔️ Slow tapering (weeks to months) is widely recommended by guidelines and experts.
✔️ Abrupt cessation or very rapid taper increases risk of symptoms.

For context, I want to share where my comments are coming from. I’ve spent more than 20 years independently investigating epidemiological data, scientific literature, and peer-reviewed medical research across a wide range of topics. My focus has always been on primary sources—original studies, systematic reviews, and consensus statements—rather than summaries, headlines, or anecdotal reports.

I make a point of cross-checking claims, understanding study design and limitations, and distinguishing between correlation, causation, and hypothesis. When evidence is incomplete or evolving, I try to say so clearly. When strong data exist, I rely on that rather than speculation or opinion.

I’m not here to persuade or argue, but to contribute information that is evidence-based, transparent, and open to correction if better data emerge. Thoughtful discussion grounded in reliable science benefits everyone, and that’s the spirit in which I participate here.
