Can you stop taking Zoloft cold turkey?
Direct Answer
Stopping Zoloft abruptly is not recommended. Like other SSRIs, sudden discontinuation can cause discontinuation syndrome, dizziness, brain zaps, nausea, irritability, and flu-like symptoms. Zoloft has a shorter half-life (26 hours) than some SSRIs, which means withdrawal symptoms may be more noticeable than with fluoxetine (Prozac), which has a very long half-life. A gradual taper over 2-4 weeks, reducing the dose by 25-50% at each step, significantly reduces these effects. Work with your prescriber to create a tapering schedule.
Based on published clinical trial data and FDA prescribing information. This is not medical advice - always consult your healthcare provider.
Supporting Evidence
Stopping Safely
SSRI discontinuation syndrome is severe and common with sertraline. Abrupt stopping causes electric shock sensations ("brain zaps"), severe dizziness, flu-like symptoms, rebound anxiety, and intense irritability.
Warning symptoms:
- "Brain zaps", electric shock sensations in the head
- Severe dizziness or vertigo
- Flu-like symptoms without fever
Side Effects
Serious (rare)
- Suicidal ideation (especially in under-25, first weeks), Black Box
- Serotonin syndrome (with other serotonergic drugs)
- Bleeding risk (especially GI with NSAIDs)
Funding transparency: Pfizer originally funded major trials. Publication bias: negative studies often unpublished. FDA analysis showed average effect size modest (NNT ~10, but much less in mild-moderate depression). See full funding details
