Ketamine vs. Traditional Antidepressants: What's the Difference?

If you or someone you love has been struggling with depression, chances are you’ve explored traditional antidepressants like SSRIs or SNRIs. But what happens when those medications don’t provide relief? At Sage Health & Wellness, we offer ketamine therapy as an innovative and promising alternative for individuals with treatment-resistant depression, anxiety, PTSD, and chronic pain.

So, how does ketamine differ from traditional antidepressants—and why are more patients considering this option? Let’s break it down.

How Traditional Antidepressants Work

Most antidepressants, such as SSRIs (Selective Serotonin Reuptake Inhibitors) and SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors), work by increasing the availability of certain neurotransmitters in the brain—mainly serotonin and norepinephrine. These chemicals play a role in mood regulation, and adjusting their levels can help improve symptoms of depression over time.

However, traditional antidepressants often:

  • Take 4–6 weeks to begin working

  • May require trying multiple medications to find the right fit

  • Can cause side effects like weight gain, sexual dysfunction, and emotional blunting

  • Don’t work effectively for up to one-third of patients

How Ketamine Works Differently

Ketamine takes a completely different approach. It targets the brain’s glutamate system, which plays a key role in mood regulation and neuroplasticity (the brain's ability to form new connections). Ketamine is thought to "reset" parts of the brain affected by depression, providing fast and sometimes dramatic relief.

What makes ketamine unique:

  • Works within hours or days, not weeks

  • Can be effective for treatment-resistant depression

  • Promotes the growth of new neural pathways

  • May also help with anxiety, PTSD, and chronic pain
