Treatment-Resistant Depression: Where Ketamine Fits in the Conversation

Important: Compounded ketamine is not FDA-approved. FDA has not evaluated its safety, effectiveness, or quality before marketing. Ketamine injection is approved for anesthesia, not psychiatric conditions. Compounded ketamine nasal spray is different from FDA-approved Spravato (esketamine), and research on other formulations or treatment settings does not establish its benefits.

When several depression treatments have not helped enough, the next step can feel discouraging. A careful review of what happened can reveal useful options and help avoid another poorly matched treatment.

Start with the treatment history

The National Institute of Mental Health describes treatment-resistant depression in the context of symptoms that do not improve after trying at least two antidepressants. A clinician still needs to review the diagnosis and whether previous treatments had an adequate dose, duration, and opportunity to help.

Bring a medication list, the dates you took each treatment, missed doses if relevant, side effects, and any changes in functioning. Include psychotherapy, sleep concerns, alcohol or other substances, and medical conditions. This information matters more than a label alone.

Review the available options

Depending on the assessment, the conversation may include adjusting medication, psychotherapy, other medication strategies, or brain-stimulation treatment. NIMH describes several approaches used when initial care is insufficient. Ask which options have evidence relevant to your situation and what their practical demands would be.

Some ketamine research has involved carefully selected adults receiving intravenous treatment under observation. That work does not establish that compounded ketamine spray at home is an effective alternative for every person with persistent depression. An approved esketamine product is a separate option with its own eligibility and monitoring requirements.

Agree on a reassessment plan

Before starting any new approach, ask how you will track symptoms and daily functioning, when progress will be reviewed, and what would prompt a change. Discuss the plan for partial benefit, no benefit, or worsening symptoms. Do not stop an existing antidepressant or alter prescribed doses without your clinician’s guidance.

Severe symptoms may require a higher level of care. If you are in immediate danger or have a medical emergency, call 911. Do not wait for an online appointment or a medication shipment.

Safety and the treatment setting

Ketamine can cause sedation, dissociation, impaired thinking or coordination, nausea, increased blood pressure or heart rate, and slowed breathing. Abuse or misuse, worsening psychiatric symptoms, and urinary or bladder problems are also concerns. This is not a complete list of risks.

At home, a healthcare professional is not onsite to monitor you or respond immediately to an adverse reaction. Telehealth support does not provide the same monitoring as an onsite care team. Review these FDA ketamine risk alerts and discuss your health history, other medications, monitoring needs, and emergency plan with your clinician.

Discuss your options

Bliss Mist Rx LLC provides telehealth services; we do not manufacture or compound medication. If a clinician prescribes treatment, an independent, appropriately licensed compounding pharmacy dispenses it. A consultation does not guarantee a prescription or a particular outcome.
