Trintellix vs. Remeron Pros and Cons

Trintellix

Trintellix's distinct mechanism makes it a reasonable option for people who have struggled with sexual side effects or weight gain on SSRIs. It has no generic version, so it typically costs more out of pocket than many older antidepressants.

Pros

  • Lower rates of sexual dysfunction than many SSRIs

  • Less associated weight gain than many antidepressants

  • Can be taken any time of day, without sedation timing

  • Simple once-daily strength schedule

Cons

  • No generic available; brand-only pricing

  • Roughly $465 to $650 per month without insurance

  • Nausea is common and dose-related, up to 32%

  • Newer drug with less long-term real-world data

Remeron

Remeron's sedating effect and appetite stimulation make it useful for people with depression who also have insomnia or poor appetite, though that same profile can be unwanted for others. It has been available as a generic for years, making it one of the least expensive antidepressants on the market.

Pros

  • Available as a low-cost generic, roughly $10-$40/month

  • Sedating effect can help with co-occurring insomnia

  • Appetite stimulation can help underweight patients

  • Available as an orally disintegrating tablet (SolTab)

Cons

  • Significant sedation, up to 54% report drowsiness

  • Weight gain and increased appetite are common

  • Requires monitoring for rare severe neutropenia

  • Bedtime dosing limits flexibility for some patients
