SSRIs vs. SNRIs: Which Antidepressant Is Right for You?
Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) are the most commonly prescribed antidepressants. Understanding how they differ can help you have more informed conversations with your provider.
How SSRIs Work
SSRIs increase serotonin levels in the brain by blocking its reabsorption. They're first-line treatments for:
- Depression
- Anxiety disorders
- OCD
- Panic disorder
- PTSD
Common SSRIs: Sertraline (Zoloft), Fluoxetine (Prozac), Escitalopram (Lexapro), Paroxetine (Paxil), Citalopram (Celexa)
How SNRIs Work
SNRIs increase both serotonin and norepinephrine. They may be preferred when:
- Chronic pain co-occurs with depression
- Fatigue and low energy are prominent symptoms
- SSRIs haven't provided adequate relief
Common SNRIs: Venlafaxine (Effexor), Duloxetine (Cymbalta), Desvenlafaxine (Pristiq)
Side Effect Considerations
Both classes can cause nausea, headache, sleep changes, and sexual side effects. SNRIs may raise blood pressure and cause more activation early on. Individual response varies significantly.
