What to do when antidepressants don’t work

First, make sure the trial was actually a fair one

A surprising number of “failed” antidepressant trials were never complete trials. The medication was started at a low dose and never raised. Side effects ended it in week two. Refills lapsed. Life got busy. None of that tells you whether the medication would have worked.

A fair trial means a therapeutic dose, taken consistently, for six to eight weeks, with some people improving further out to twelve. If your trials were cut short or underdosed, the right next step may simply be doing one properly, with closer support. That is worth knowing before moving to bigger interventions.

Five reasons antidepressants fall short

• The diagnosis is incomplete. Bipolar depression, thyroid problems, sleep apnea, ADHD, and substance use can all look like “depression that won’t respond.” Antidepressants alone don’t fix any of them.
• The dose or duration was inadequate. See above; this is the most fixable reason on the list.
• Side effects keep ending treatment. If potentially helpful medicines remain intolerable, the overall treatment strategy needs review.
• The depression is treatment-resistant. Up to 31% of people with depression may not respond adequately to medications and meet criteria for treatment resistance, which calls for consideration of alternative or interventional treatments. In STAR*D, a large real-world study, the likelihood of remission generally declined across successive treatment steps.
• Something in life is doing the maintaining. Grief, an unsafe relationship, chronic pain, night-shift work. Medication can help you cope; it can’t resolve the circumstance. Therapy targets this directly.

What the next step actually looks like

The sequence starts with a fresh, thorough evaluation: full history, prior medications with doses and durations, medical workup, and screening for the look-alike conditions above. From there, the options run in rough order of intensity:

1. 1

   Optimize or switch

   Raise an underdosed medication, complete an interrupted trial, or switch to a different class. Augmentation, adding a second medication to a partial responder, is another evidence-based move.

2. 2

   Add psychotherapy

   Medication and therapy together outperform either alone for many people, and therapy is the primary treatment when life circumstances are doing the maintaining.

3. 3

   Interventional treatments

   After two or more adequate antidepressant trials, options with different mechanisms may include TMS (device- and protocol-specific FDA clearance), Spravato® (FDA-approved for adult treatment-resistant depression), and IV ketamine (FDA-approved as an anesthetic; psychiatric use is off-label). Coverage for TMS and Spravato depends on the specific plan and prior-authorization criteria.

When to see a psychiatrist about it

If two adequate trials haven’t brought real relief, a psychiatric evaluation can reassess the diagnosis and identify which of several different tools may fit. That question benefits from a physician who can prescribe, order a medical workup, and deliver interventional options under one roof.

At Fortifying Wellness in Littleton, that evaluation is a 90-minute appointment with Eric Wagner, MD, and it starts with a free consultation. If you’re anywhere in Colorado, evaluations and follow-ups are also available by telehealth.
