What Is Zoloft?

Sertraline (commonly known as Zoloft) is an SSRI antidepressant widely used to treat:

• Depression
• Generalized anxiety disorder
• Panic disorder
• PTSD
• Social anxiety disorder

Zoloft works by increasing serotonin levels in the brain, which helps improve mood, emotional stability, and overall mental well-being.

Many patients searching for Zoloft vs Prozac are trying to understand which medication might be more suitable for long-term use.

What Is Prozac?

Fluoxetine (Prozac) is another widely used SSRI medication. It is often prescribed for:

• Major depressive disorder
• Obsessive-compulsive disorder (OCD)
• Bulimia nervosa
• Panic disorder
• Premenstrual dysphoric disorder (PMDD)

Prozac has a longer half-life compared to many SSRIs, meaning it stays in the body longer and may produce more stable effects over time.

When comparing Zoloft vs Prozac, this difference in metabolism becomes very important.
