Depression is one of the most common and most treatable conditions in all of medicine. And yet, according to national data, only about half of people with depression receive any treatment. That gap is one of the things that motivates my work as a psychiatric provider.
If you are living with depression — or supporting someone who is — this guide is intended to give you a comprehensive, honest overview of what treatment actually looks like.
First: Is It Depression?
Depression is not just sadness. It is a clinical syndrome that involves persistent low mood or loss of interest in activities, along with a cluster of associated symptoms — changes in sleep, appetite, energy, concentration, and self-worth — that last at least two weeks and impair functioning.
Grief, adjustment to major life changes, and stress can all produce depressive-like symptoms. A psychiatric evaluation helps clarify the picture and ensures you get the right treatment.
Antidepressant Medications
Medication is the most commonly used treatment for moderate to severe depression, and it is highly effective for many people. The main classes include:
- SSRIs (selective serotonin reuptake inhibitors): First-line treatment. Examples include sertraline, escitalopram, fluoxetine, paroxetine. Well-tolerated with good evidence.
- SNRIs (serotonin-norepinephrine reuptake inhibitors): Also first-line. Venlafaxine and duloxetine are examples. May also help with anxiety and pain.
- Bupropion: An NDRI — often used when SSRIs cause sexual side effects or fatigue. Also helpful for focus and energy.
- Mirtazapine: Sedating — useful when insomnia and poor appetite are significant.
- Tricyclics and MAOIs: Older medications, highly effective, used when other options have not worked.
Psychotherapy
Therapy is a powerful treatment for depression — particularly Cognitive Behavioral Therapy (CBT), which directly targets the negative thought patterns and behavioral withdrawal that maintain depression.
Interpersonal therapy (IPT) focuses on relationship dynamics and life transitions. Behavioral activation — simply increasing engagement in meaningful activities — is one of the most evidence-based and underutilized interventions for depression.
For mild to moderate depression, therapy alone is often sufficient. For moderate to severe depression, medication plus therapy outperforms either alone.
Lifestyle Factors That Matter
This is not about telling you to "just exercise." But the evidence for exercise as a treatment for depression is genuinely strong — comparable to antidepressant medication for mild to moderate cases. Thirty minutes of moderate-intensity aerobic exercise most days of the week has a clinically meaningful effect on mood.
Sleep quality, social connection, nutrition, and limiting alcohol also matter. Alcohol is a depressant — it disrupts sleep and directly worsens mood over time, even though it can feel like relief in the moment.
When First-Line Treatment Does Not Work
About a third of people with depression do not achieve remission with the first antidepressant tried. This is called treatment-resistant depression (TRD). Options for TRD include:
- Augmentation: Adding a second medication (lithium, atypical antipsychotics, thyroid hormone) to boost the primary antidepressant
- Switching to a different antidepressant class
- Transcranial magnetic stimulation (TMS): A non-invasive brain stimulation therapy with FDA approval for TRD
- Ketamine infusion or intranasal esketamine (Spravato): Rapid-acting for severe TRD
- Electroconvulsive therapy (ECT): Highly effective for severe, treatment-resistant depression — much safer and more humane than popular culture suggests
How Long Should You Stay on an Antidepressant?
This is a common and important question. For a first episode of depression, most guidelines recommend continuing medication for at least 6 to 12 months after achieving remission, to reduce the risk of relapse.
For people with recurrent depression (two or more episodes), longer-term or indefinite treatment is often recommended. This is a conversation to have with your provider based on your history.
