You've been on medication for weeks. Nothing's changed—or maybe you feel worse. Here's what to consider and what to try next.
First: Has It Actually Failed?
Have You Given It Enough Time?
- Most antidepressants take 4-8 weeks for full effect
- Some improvement should appear by week 2-4
- If zero improvement by week 6-8, it's probably not working
Is the Dose Right?
Many people are on subtherapeutic doses. Starting doses are often not treatment doses. Ask your doctor if there's room to increase.
Are You Taking It Consistently?
Missing doses regularly significantly reduces effectiveness.
Why Medication Might Not Work
- Wrong medication for your depression subtype
- Metabolic differences (some people metabolize drugs faster)
- Misdiagnosis (e.g., bipolar depression responds differently)
- Substance use interfering
- Untreated medical conditions (thyroid, sleep apnea)
- Severe life stressors overwhelming medication effects
Next Steps
Optimize Current Medication
- Increase dose if possible
- Ensure consistent timing and adherence
- Address factors that interfere (alcohol, other drugs)
Switch Medications
- Try different SSRI (different people respond to different ones)
- Try different class (SNRI, bupropion, mirtazapine)
- Each medication has 50-60% response rate—failure of one doesn't predict failure of others
Augment
- Add second medication to boost first (aripiprazole, lithium, thyroid)
- Add therapy if not already doing it
- This approach often helps when switching alone doesn't
Treatment-Resistant Depression Options
If you've tried 2+ medications without adequate response:
- Spravato (esketamine) - FDA approved for treatment-resistant depression
- TMS (transcranial magnetic stimulation)
- ECT (electroconvulsive therapy) - most effective for severe cases
- Ketamine infusions
- Clinical trials for novel treatments
Treatment-resistant depression is treatable. Options exist beyond standard antidepressants. Don't give up.
Questions to Ask Your Doctor
- 'Am I on an adequate dose?'
- 'Should we try a different medication or class?'
- 'Should we add something to what I'm taking?'
- 'Could this be something other than depression?'
- 'Should I see a psychiatrist?' (if you're seeing a PCP)
- 'Are there other options like TMS or ketamine?'
The Bottom Line
One medication not working doesn't mean nothing will. Most people find something that helps—it just takes trial and error. Stay in communication with your prescriber, consider adding therapy, and know that advanced options exist for treatment-resistant cases.
