Zoloft vs. Xanax: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 28, 2023
Zoloft is an SSRI antidepressant, while Xanax is a benzodiazepine for anxiety.

Key Differences

Zoloft and Xanax are both prescription medications but serve different purposes. Zoloft, a brand name for sertraline, is an SSRI used to treat depression, while Xanax, a brand name for alprazolam, is a benzodiazepine used to treat anxiety and panic disorders.
Zoloft works by increasing serotonin levels in the brain, which can help improve mood and alleviate symptoms of depression. On the other hand, Xanax works by enhancing the effects of GABA, a neurotransmitter, leading to sedation and decreased anxiety.
Side effects of Zoloft can include nausea, sleepiness, and weight changes. For Xanax, side effects can include drowsiness, addiction potential, and dizziness.
While Zoloft is often prescribed for long-term use to treat depression and certain anxiety disorders, Xanax is generally prescribed for short-term use due to its potential for dependence and tolerance.
It's crucial for patients to consult with their healthcare providers before stopping or switching between Zoloft and Xanax, as both medications can have withdrawal effects if not tapered properly.
