Pristiq vs. Sertraline
See how Pristiq and Sertraline compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Sertraline has FDA approval for six conditions, including OCD, panic disorder, PTSD, social anxiety disorder, and PMDD, while Pristiq is approved only for major depressive disorder in adults.
Pristiq's 50 mg starting dose is also its full therapeutic dose, while sertraline typically needs titration from 50 mg up to a maximum of 200 mg over several weeks.
Generic sertraline usually costs $20 to $75 a month without insurance, far less than Pristiq's typical $400 to $543 monthly list price.

Pristiq vs. Sertraline Indications
Pristiq
Pristiq is FDA-approved only for major depressive disorder in adults. It doesn't carry approval for anxiety, OCD, or other conditions, though clinicians sometimes prescribe it off-label for these uses.
Major depressive disorder (MDD) in adults
Not approved for pediatric patients
Off-label: generalized anxiety disorder (not FDA-approved)
Off-label: hot flashes from menopause (not FDA-approved)
Sertraline
Sertraline is FDA-approved for six conditions: MDD, OCD, panic disorder, PTSD, social anxiety disorder, and PMDD. This broad label makes it a common first choice when depression overlaps with anxiety-related conditions.
Major depressive disorder (MDD) in adults
Obsessive-compulsive disorder (OCD), ages 6+
Panic disorder, PTSD, and social anxiety disorder
Premenstrual dysphoric disorder (PMDD)
Pristiq vs. Sertraline Pros and Cons
Pristiq
Pristiq offers simple, no-titration dosing since 50 mg is both the starting and full therapeutic dose. As an SNRI, it also affects norepinephrine, which some patients tolerate differently than SSRI-only options like sertraline.
Pros
50 mg dose usually works without titration
Minimal liver metabolism means fewer drug interactions
Dual-action SNRI may help if SSRIs alone haven't worked
Simple once-daily extended-release tablet
Cons
Approved only for depression, not anxiety-related conditions
Can raise blood pressure, requiring monitoring
Costs roughly $400 to $543 a month without insurance
Discontinuation symptoms can be more pronounced (SNRI)
Sertraline
Sertraline's broad approval and decades of use make it a common first-line choice for depression and several anxiety-related disorders. As an SSRI, it avoids the blood-pressure effects sometimes seen with SNRIs like Pristiq.
Pros
FDA-approved for six conditions beyond depression
Decades of real-world use and safety data since 1991
No blood-pressure effects typical of SNRIs
Generic version costs $20 to $75 a month
Cons
Often needs several weeks of titration to reach full dose
Higher rates of sexual side effects like ejaculation failure
GI side effects such as diarrhea are more common
More potential for CYP-mediated drug interactions
