You started the medication hopeful. You waited the four to eight weeks your doctor said it would take. Maybe something shifted — or maybe nothing did. Either way, you’re still here, still struggling, and starting to wonder if this is just how things are going to be.
We hear this at AlphaOmega Wellness more than almost anything else. Patients come to us not because they gave up on getting better, but because they kept trying — and the antidepressants they were given didn’t get them there. If your antidepressant isn’t working, that is not a failure on your part. It may simply mean your brain needs a different kind of help.
Here’s how to recognize the signs, what to do next, and what options exist for patients in Indiana who are ready to try something that actually works on the brain — not just around it.
Signs Your Antidepressant Isn’t Working
It’s not always obvious. Some people feel a partial improvement and assume that’s as good as it gets. Others feel nothing at all and wonder if they should push through longer. Here are the signs worth paying attention to:
1. You’ve been on it for 8+ weeks and still feel the same
Most antidepressants take 4 to 8 weeks to reach their full effect. If you’re past that window and your core symptoms — low mood, loss of interest, fatigue, hopelessness — haven’t meaningfully improved, that’s a signal the medication may not be the right fit. Waiting longer rarely changes the outcome at this point.
2. You feel better in some ways but still can’t function
Partial response is one of the most frustrating experiences in depression treatment. You might sleep a little better, or feel slightly less dark — but you still can’t motivate yourself to do basic things, still can’t feel joy, still can’t show up the way you want to for your family or your work. Partial response is not the goal. Meaningful recovery is.
3. The side effects are making your life harder
Sexual dysfunction. Emotional blunting — that flat, numbed-out feeling where nothing seems to matter much. Weight gain. Insomnia. Brain fog. These are real, common side effects of many antidepressants, and for some patients they’re severe enough to make the treatment feel worse than the disease. If side effects are significantly impacting your quality of life, that conversation needs to happen with your doctor.
4. It worked for a while and then stopped
This is called antidepressant tachyphylaxis, or more informally, “poop-out.” The medication worked — maybe really well — and then gradually or suddenly it stopped being effective. This is more common than most patients realize and often leads to a frustrating cycle of dose increases and medication switches that can go on for years.
5. You’ve already tried two or more antidepressants
By clinical definition, failing to respond to two or more antidepressants at adequate doses is called treatment-resistant depression. It affects roughly one in three people who are treated for depression. If this is you, you are not broken and you are not uniquely difficult to treat — you may simply need a treatment that works through a different mechanism entirely.
6. Your depression is getting worse, not better
If you’re on an antidepressant and your symptoms are worsening — particularly if you’re experiencing thoughts of self-harm or suicide — this requires immediate attention. Do not wait for a scheduled follow-up. Call your prescriber, go to an urgent care, or reach out to a crisis line. If you’re in Indiana and want to talk to our team about rapid-acting options, we’re here.
Why Antidepressants Don’t Always Work
The standard explanation for depression — that it’s caused by low serotonin and antidepressants fix it by raising serotonin — is increasingly being questioned by neuroscientists. A landmark 2022 review in Molecular Psychiatry found no consistent evidence that low serotonin causes depression.
What we do know is that depression involves real structural changes in the brain. The prefrontal cortex and hippocampus — areas responsible for mood regulation, memory, and decision-making — can physically shrink under the weight of chronic depression. Antidepressants that work on serotonin levels don’t directly address these structural changes. That’s why they work well for some people and not at all for others.
This is also why newer approaches that target neuroplasticity — the brain’s ability to form new connections and rebuild itself — are showing results that traditional antidepressants can’t match for treatment-resistant patients.
What to Do When Your Antidepressant Isn’t Working
Talk to your prescriber honestly
The first step is always an honest conversation with whoever prescribes your medication. Be specific: what symptoms are still present, how long you’ve been on the current dose, what side effects you’re experiencing. Ask directly: “Is this the best we can do, or are there other options?” You deserve a complete answer.
Don’t stop your medication abruptly
Even if it isn’t working, stopping an antidepressant suddenly can cause significant withdrawal symptoms — dizziness, nausea, intense mood swings, and what many patients describe as “brain zaps.” Any changes to your medication should happen gradually and in coordination with your doctor.
Ask about augmentation strategies
Sometimes adding a second medication to your existing antidepressant can improve response. Options like lithium, atypical antipsychotics, or thyroid hormone have evidence behind them as augmentation strategies. These aren’t right for everyone but are worth discussing.
Consider therapy alongside medication
The research consistently shows that combining medication with therapy — particularly cognitive behavioral therapy (CBT) — produces better outcomes than either alone. If you’re only on medication and haven’t engaged with therapy, that’s worth exploring.
Ask about ketamine therapy
IV ketamine therapy works through a completely different mechanism than antidepressants. Rather than adjusting serotonin levels, research suggests it works on the glutamate system to stimulate neuroplasticity — the regrowth of synaptic connections that chronic depression has damaged. Many patients who have failed two, three, or four antidepressants respond well to ketamine. Changes often appear within hours to days, not weeks.
At AlphaOmega Wellness in Greenwood, Indiana, we have completed more than 5,000 infusions. Every infusion is conducted under the medical direction of Dr. Dee Bonney, MD — a board-certified emergency physician with 25+ years of experience — with ACLS-certified clinical staff present at all times. If your antidepressant isn’t working and you’re ready to explore what else is possible, a free consultation is a good place to start.
What That Looked Like for One Patient
Treatment-Resistant Depression Is More Common Than You Think
If you’ve tried multiple antidepressants without adequate relief, you’re not an outlier. Roughly one in three people treated for depression will meet the criteria for treatment-resistant depression. The problem isn’t your willpower, your attitude, or how hard you’re trying. It’s that the tools you’ve been given weren’t designed for the way your brain responds.
The good news is that treatment-resistant depression is exactly where IV ketamine therapy has the strongest evidence. Research suggests it helps a meaningful share of people who have not responded to traditional antidepressants. For a population that has often been told there’s nothing left to try, that matters.
We serve patients from Greenwood, Indianapolis, Carmel, Fishers, and across Central Indiana. If you’re in this category and you haven’t explored ketamine therapy yet, we’d encourage you to learn more. Your brain can still heal — it may just need a different kind of help than what you’ve been given so far.

Frequently Asked Questions
How long should I give my antidepressant before deciding it isn’t working?
Most antidepressants take 4 to 8 weeks to reach full therapeutic effect. If you’re past 8 weeks at an adequate dose and your core symptoms haven’t meaningfully improved, that’s a reasonable point to have a conversation with your prescriber about next steps. Waiting longer than 8 to 12 weeks without improvement rarely changes the outcome.
Is it normal to try multiple antidepressants before finding one that works?
Yes — and unfortunately, more common than most patients are told upfront. Roughly one in three people with depression don’t respond adequately to their first antidepressant. By clinical definition, failing two or more antidepressants at adequate doses is called treatment-resistant depression. It doesn’t mean you can’t get better — it may mean you need a different type of treatment.
Can I just stop taking my antidepressant if it isn’t working?
No — stopping antidepressants abruptly can cause significant discontinuation symptoms including dizziness, nausea, mood instability, and brain zaps. Any changes to your medication should be made gradually and in coordination with your prescribing doctor. Even if the medication isn’t helping, the tapering process matters.
What is treatment-resistant depression?
Treatment-resistant depression is generally defined as depression that hasn’t responded adequately to two or more antidepressants at appropriate doses and durations. It affects an estimated one in three people treated for depression. It’s not a life sentence — it’s a clinical category that points toward different treatment approaches, including IV ketamine therapy, which has strong evidence specifically in this population.
Does ketamine therapy work if antidepressants haven’t?
Often, yes — and this is where ketamine has the strongest evidence. Because it works through a completely different mechanism (the glutamate system and neuroplasticity) rather than serotonin, research suggests it can help where antidepressants have not. At AlphaOmega Wellness, many of our patients come to us after failing two, three, or more antidepressants and go on to experience meaningful relief. It does not work for everyone, which is why a medical evaluation comes first.
Can I do ketamine therapy while still taking my antidepressant?
In most cases, yes. The majority of our patients continue their current medications through the ketamine series. There are a few exceptions — particularly MAOIs and high-dose benzodiazepines — which is why we review your complete medication list during your free consultation before recommending treatment. Any medication changes happen in coordination with your prescribing physician over time.
How quickly does ketamine therapy work compared to antidepressants?
This is one of the most striking differences. Many patients notice a meaningful shift within 24 to 48 hours of their first infusion — sometimes sooner. Antidepressants typically require 4 to 8 weeks before you know whether they’re working. For patients who have been struggling for months or years without relief, that speed of response can matter a great deal.
Is ketamine therapy available in Indiana?
Yes. IV ketamine therapy is federally legal and available right now at AlphaOmega Wellness in Greenwood, Indiana — serving patients from Indianapolis, Carmel, Fishers, and across Central Indiana. You don’t need to wait for any new legislation or travel out of state. Book a free consultation to learn whether it’s the right fit for you.
What does a ketamine therapy consultation involve?
Your free consultation at AlphaOmega Wellness is a real conversation — not a checklist. We review your mental health history, current medications, previous treatments, and what you’re hoping to achieve. Our Brain Health Specialist will give you an honest assessment of whether IV ketamine therapy is likely to be a fit, and answer every question you have. There’s no pressure and no obligation.
