Which SSRI has a long half-life and may require gradual tapering when stopping?

Explanation:
Understanding how long an SSRI stays in the body helps explain withdrawal risk. Fluoxetine has the longest half-life among the SSRIs, and its active metabolite can linger for weeks after the last dose. Because elimination is so slow, stopping it can leave drug levels in flux for a long time, so a gradual taper is often considered to minimize any withdrawal effects as the medication is washed out. The other SSRIs clear more quickly, so stopping them can produce more immediate discontinuation symptoms, with paroxetine being particularly notorious for withdrawal due to its shorter half-life. So, the one with the long half-life and the potential need for tapering is fluoxetine.
