If you’ve been battling depression for months or even years, trying medication after medication with little to no improvement, you’re not alone. The frustration and exhaustion of ongoing symptoms despite treatment can feel overwhelming.
Treatment-resistant depression (TRD) is simply defined as depression that does not improve after at least two adequate antidepressant trials. It’s a genuine medical condition that requires specialised care, and does not reflect personal failure or lack of trying.
What Is Treatment-Resistant Depression?
TRD is diagnosed when someone fails to respond to two or more first-line antidepressants taken for 6-8 weeks each at therapeutic doses. This means you’ve given the medications sufficient time and correct dosing, yet your symptoms persist.
Research shows that TRD affects approximately 30% of people diagnosed with major depressive disorder, making it far more common than many realise. Understanding this can help validate your experience and encourage you to seek the specialised support you deserve.

Signs That Your Depression May Be Treatment-Resistant
Recognising TRD early can help you access appropriate treatment sooner. Consider these important questions about your experience:
Have You Tried Multiple Medications Without Relief?
If you’ve been prescribed two or more antidepressants and followed your doctor’s instructions carefully but still experience significant depressive symptoms, this is a primary indicator of TRD.
Many people with treatment resistant depression in Australia have tried Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin and Norepinephrine Reuptake Inhibitor (SNRIs_, or other antidepressant classes without finding adequate relief. This pattern suggests your depression may require alternative treatment approaches beyond conventional medications.
Note: SSRIs (Selective Serotonin Reuptake Inhibitors) and SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) are common types of antidepressants that work by balancing brain chemicals (serotonin and norepinephrine) to help improve mood and reduce symptoms of depression.
Are Your Symptoms Persistent and Severe?
Do you continue experiencing intense feelings of hopelessness, worthlessness, or emptiness despite treatment?
When symptoms remain severe enough to interfere with work, relationships, or daily activities after multiple medication trials, it may indicate TRD. Persistent symptoms that don’t budge despite treatment are a hallmark sign that you may need to explore what to do when antidepressants are not working.
Do You Experience Fluctuating or Relapsing Symptoms?
Have you noticed a pattern where your depression seems to improve temporarily, only to return with full force? Some people with TRD experience partial responses to treatment followed by relapses.
This cycling pattern, where medications work briefly then lose effectiveness, can be particularly discouraging and is another important sign to discuss with your psychiatrist.
Are Lifestyle Changes and Therapy Not Helping?
Have you committed to therapy, exercise, improved sleep habits, and dietary changes but still struggle with depression? While these interventions are valuable, when combined with medication they should typically provide some relief.
If you’re doing everything right but still feel stuck, your depression may be treatment-resistant and require advanced interventions at a specialised clinic for depression treatment.
Do You Have Physical Symptoms That Don’t Respond to Treatment?
Are you experiencing persistent fatigue, pain, digestive issues, or sleep problems that haven’t improved with antidepressants? Depression often manifests physically, and when these symptoms remain unchanged despite treatment, it may signal TRD. Physical symptoms that resist standard treatment approaches often respond better to innovative therapies.
What Should You Do If You Suspect You Have TRD?
If you recognise these signs, don’t lose hope. Advances in psychiatric treatment have created new pathways to recovery. Speaking with a psychiatrist who specialises in TRD is crucial. They can reassess your diagnosis, review your treatment history, and explore advanced options.
Modern treatments like transcranial magnetic stimulation (TMS) treatment offer non-invasive approaches that work differently from traditional medications. TMS uses magnetic pulses to stimulate brain regions involved in mood regulation.
Additionally, esketamine for treatment-resistant depression has shown promising results for people who haven’t responded to other treatments. When considering esketamine vs TMS, your psychiatrist can help determine which option best suits your specific situation and medical history.
It’s also important to ensure any co-existing conditions are addressed. Sometimes anxiety, trauma, or other mental health conditions can complicate depression treatment. A comprehensive evaluation can identify these factors and guide more effective treatment planning.
Many patients wonder about life after TMS or other advanced treatments. The reality is that many people who struggled for years with TRD find significant improvement through these innovative approaches. Recovery is possible, and new treatments continue to emerge, offering hope where traditional approaches have fallen short.

Finding Hope and Moving Forward
Treatment-resistant depression is a complex medical condition requiring specialised expertise and innovative approaches. If you’ve tried multiple treatments without success, you’re not weak or broken – your brain simply needs a different approach. These signs aren’t meant to discourage you, but to validate your experience and point you toward appropriate help.
