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
