Spravato for Treatment-Resistant Depression: How It Works

December 5th, 2027

Most people who start an antidepressant get some relief. A meaningful number do not, and the standard next move has historically been to try another one, then another. For those patients, the process can stretch over months with little to show for it. Spravato exists for that group.

Spravato, or esketamine, is an FDA-approved nasal spray for treatment-resistant depression and for major depressive disorder with acute suicidal thoughts or behavior. It is not a first-line treatment, and it is not a take-home medication. It is a supervised treatment that works differently from standard antidepressants.

What Treatment-Resistant Depression Means

Treatment-resistant depression usually refers to major depression that has not improved enough after at least two different antidepressant trials at adequate doses and durations. It is not a statement about the person's effort or character. It describes how the illness responded to medication so far.

People in this group often describe a long history of trials: a medication that helped a little, a dose increase, a switch, an add-on, and then another switch. By the time Spravato is considered, many have been depressed for years.

How Spravato Is Different

Most antidepressants work on serotonin, norepinephrine, or dopamine. Esketamine works on the NMDA receptor, part of the glutamate system, which is involved in mood regulation and the brain's ability to form new connections.

That different mechanism has two practical consequences. First, it can work for people who did not respond to standard antidepressants. Second, it can work faster. Some patients report improvement within hours to days rather than the weeks required by oral antidepressants.

Spravato is used alongside an oral antidepressant, not instead of one. The combination is what was studied and what is approved.

What an Appointment Looks Like

Because of the risks of sedation and dissociation, Spravato is only available through a restricted program called a REMS program. That means it is administered in a certified setting under medical supervision.

• You self-administer the nasal spray under a provider's observation.
• You remain at the office for monitoring for at least two hours after the dose.
• Your blood pressure is checked before and after.
• You cannot drive yourself home, so plan for a ride.

Treatment is usually given twice a week for the first month, then weekly, with the schedule tapering over time. Many patients continue maintenance doses every one to two weeks.

Who May Qualify

Spravato is approved for adults with treatment-resistant depression or major depressive disorder with acute suicidal ideation or behavior. Candidacy depends on a full evaluation: your depression history, the medications you have tried, your medical history, and your blood pressure.

It is not appropriate for everyone. People with certain cardiovascular conditions, aneurysms, or a history of substance use disorder need a careful risk discussion. Your provider will go through this with you.

What to Expect in the Weeks After

Response varies. Some people feel a shift after the first few doses. Others see improvement over several weeks. Because the effect can fade between doses, the schedule matters, and the oral antidepressant continues throughout.

Common side effects during and shortly after a dose include:

• Dissociation, or a feeling of being spaced out or disconnected
• Dizziness and sedation
• Nausea
• Temporary increases in blood pressure
• Headache

These usually resolve within a couple of hours, which is why the observation period exists. You should not drive, operate machinery, or make major decisions until you feel fully back to normal.

How It Fits With Other Treatments

Spravato is one option among several for depression that has not responded to standard treatment. Transcranial magnetic stimulation is another, and it works through a different mechanism without medication. Therapy, lifestyle changes, and treatment of co-occurring conditions remain part of the plan.

The right choice depends on your history, your health, your schedule, and what you have already tried. That is a conversation, not a menu.

Is It Covered?

Coverage varies by insurance plan. Spravato is typically covered for approved indications, though prior authorization is usually required. The practice can help you understand what your plan requires before treatment starts.

Next Steps

If you have tried two or more antidepressants without enough improvement, Spravato is worth asking about. You are not out of options, and you are not a difficult patient because standard treatment has not worked yet.
