SSRI (Selective Serotonin Reuptake Inhibitor)

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.

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 Publication bias: negative studies often unpublished.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
