Zoloft vs. Trintellix Pros and Cons

Zoloft

Zoloft has decades of real-world use and a well-documented safety record across many conditions. It is available as an inexpensive generic, though sexual side effects and GI upset are common early on.

Pros

  • Approved for six different conditions, useful if diagnoses overlap

  • Available as generic sertraline for as little as $10 to $75 a month

  • Long track record since 1991 with extensive safety data

Cons

  • Higher rates of sexual dysfunction, including ejaculation problems in men

  • GI side effects like nausea and diarrhea are common early on

  • Often needs weekly dose changes to reach an effective dose

  • Same mechanism as other SSRIs a patient may have already tried

Trintellix

Trintellix works through a different mechanism than SSRIs, which can help patients who did not respond well to drugs like Zoloft. It has no generic version, so it costs well above generic sertraline.

Pros

  • Distinct mechanism, an option after SSRIs have not worked

  • Lower rates of sexual dysfunction and weight gain than many SSRIs

  • Simple once-daily dosing with usually only one adjustment step

Cons

  • No generic; costs roughly $465 to $650 a month without insurance

  • Nausea can affect up to 32% of patients depending on dose

  • Newer drug (2013) with less long-term real-world data than Zoloft
