Some people try one antidepressant and feel better within weeks. Others try five, six, seven, and nothing really moves the needle.
If that second version sounds familiar, esketamine might be worth knowing about.

What Counts as Treatment-Resistant

Doctors don’t throw this term around casually. It usually means someone has tried at least two different antidepressants, at proper doses, for long enough to know if they were working, and neither one helped.
Months of waiting. Side effects that didn’t even come with a payoff. A lot of people who end up considering esketamine have already been through that more than once.

Not Your Typical Antidepressant

It is worth noting that most antidepressants work on serotonin or similar brain chemicals. Esketamine, on the other hand, targets glutamate.
As we know, depression over long periods of time wears down connections between brain cells. Part of the reason that esketamine seems to work for people who haven’t responded to anything else is because it seems to help rebuild these connections.
This is a nasal spray not pill. It’s typically combined with an oral antidepressant.

The Two Groups the FDA Approved It For

There are really two situations where esketamine gets approved.
One is treatment-resistant depression in adults, meaning the standard route of trying medication after medication hasn’t worked. The other is major depressive disorder with suicidal thoughts or behavior, where waiting weeks for a slow-acting medication to kick in just isn’t good enough.
In that second case, someone doesn’t necessarily need a long treatment history first. The urgency of what’s happening is enough on its own.

What a Provider Actually Checks

Getting approved for esketamine isn’t as simple as asking for it. A provider needs to see a real record of what’s been tried before, what doses, for how long, and why it didn’t pan out.
There’s also a full diagnosis process, done by someone qualified in psychiatry, not just a general checkup. Certain health conditions can rule esketamine out, so a medical history review happens before anything else.
Current medications matter too. Nobody has to stop taking their existing antidepressant to start esketamine, but a provider needs the full list before moving forward.

Why You Can’t Just Take It Home

The FDA put esketamine under something called a REMS program, which stands for Risk Evaluation and Mitigation Strategy. In plain terms, it means the drug can only be given in a certified clinical setting.
There’s a reason for that. Some people feel sedated or a little detached from reality in the hours right after treatment. So every session includes monitoring, usually about two hours, before anyone’s cleared to leave.
Driving yourself home isn’t an option either. You’ll need someone to take you.

The First Visit

The first appointment usually runs about an hour. Most of that time goes toward walking through your history, what medications you’ve tried, how long you stuck with each one, what side effects showed up, why things got stopped.
Sometimes a physical exam gets added to the mix, mainly to catch anything that would make esketamine unsafe. By the end, the provider will tell you whether it’s a fit, and if it is, they’ll put together a plan.

What Treatment Actually Looks Like

It starts intense and slows down over time.
Twice a week for the first month is typical, then once a week for a few more weeks, then eventually every couple of weeks as a maintenance schedule.
It’s not something you do once and walk away from.
Most people keep it going alongside therapy or their regular medication, as one piece of a bigger plan rather than a fix on its own.

How Shifa Health Approaches It

At Shifa Health, esketamine isn’t handed out as a quick solution. It comes after a real look at what’s already been tried, guided by board-certified psychiatric providers who take the time to understand the full picture first.
Treatment is available at the Everett and Mount Vernon locations, with the Marysville location joining next month, and proper monitoring built into every appointment.
Because it’s FDA-approved and delivered through the REMS system, insurance usually covers it, which matters a lot for people who’ve already spent years trying to find something that works.
If anything else hasn’t worked, or things have gotten to the point that you’re not feeling safe in waiting any longer, it’s worth contacting Shifa Health and seeing if esketamine is a part of the solution.
