If you’ve tried two or more antidepressants and still feel trapped by depression, you’re not alone. Treatment-resistant depression affects millions of people who’ve exhausted conventional options. But there’s hope in the form of a breakthrough therapy that works differently from traditional medications. Spravato therapy (esketamine nasal spray) has changed the trajectory for countless patients who didn’t respond to standard antidepressants. At Catalyst Health & Wellness, we’ve seen firsthand how rapid-acting treatments like Spravato can restore hope and momentum in lives that seemed stuck. If you’re wondering whether Spravato might be your answer, this guide breaks down what it is, how it works, who it’s for, and what to expect.
What Is Spravato Nasal Spray?
Spravato is the brand name for esketamine, a form of the medication ketamine delivered directly into your nose as a nasal spray. Think of it as a different path around the traditional antidepressant route. While most antidepressants like SSRIs or SNRIs work by increasing serotonin or norepinephrine in your brain, Spravato takes a completely different approach. It targets your brain’s glutamate system, which plays a crucial role in how your brain cells communicate and adapt.
In 2019, the FDA approved Spravato specifically for treatment-resistant depression, marking the first time an NMDA receptor antagonist became available as a nasal spray for mental health. This approval represented a watershed moment for patients who’d run out of options with traditional medications. More recently, in January 2025, the FDA expanded its approval to make Spravato the first and only monotherapy for adults who haven’t responded adequately to at least two antidepressants. This new indication means Spravato can be used alone without necessarily combining it with another antidepressant, giving patients and doctors more flexibility in treatment planning.
How Spravato Works
Understanding Spravato’s mechanism helps explain why it’s so effective when other treatments fail. Most traditional antidepressants work by increasing the availability of neurotransmitters like serotonin. They work on the same basic brain chemistry pathway that’s been targeted for decades. Spravato takes an entirely different route. It blocks NMDA receptors in your brain, receptors that are normally active in ways that can perpetuate depression. When you take Spravato, it essentially taps the brakes on these overactive receptors, which triggers a cascade of profound changes.
This action leads to increased levels of glutamate, the brain’s most abundant neurotransmitter, and activates downstream pathways that promote brain cell growth and reconnection between cells. This process is called neuroplasticity. Because of this unique mechanism, your brain can begin healing in hours or days rather than the weeks or months typical with standard antidepressants. The nasal spray formulation allows Spravato to reach your bloodstream and brain rapidly, with peak effects within 20 to 40 minutes of administration. This fast delivery is why many patients experience relief so quickly.
Is Spravato Effective?
The clinical evidence is compelling and backed by rigorous FDA trials. In landmark studies, patients receiving Spravato showed measurable improvement in depression symptoms within 24 hours. This speed is remarkable. Compare that to SSRIs, which can take four to six weeks to show any benefit. By week 4 of Spravato treatment, 22.5% of patients receiving the medication achieved remission—defined as essentially no depression symptoms—compared with just 7.6% of those taking placebo. That’s roughly a threefold difference, and these patients had all failed at least two other antidepressants.
When combined with an oral antidepressant, Spravato produced remission rates of 16.7%, versus only 2.9% with an antidepressant alone. For people who’ve been depressed for years despite trying multiple medications, these numbers represent real hope. These aren’t marginal improvements; they’re transformative gains. One patient described Spravato treatment as ‘waking up from a five-year nightmare.’ Another said the relief was so profound they finally understood what it meant to feel normal again. Research also indicates that Spravato maintains its effectiveness over time with maintenance dosing, helping patients sustain their gains and avoid relapse. Many patients who achieve improvement continue on maintenance sessions ranging from weekly to monthly, depending on their response.
Who Is Spravato Right For?
Spravato isn’t for everyone, but it’s specifically designed for your situation if you’ve struggled with treatment-resistant depression. You’re a candidate if you’ve had inadequate response to at least two antidepressant treatments taken for sufficient time at adequate doses. This might mean SSRIs, SNRIs, tricyclic antidepressants, or other oral medications simply didn’t work. You’re also a candidate if you’re experiencing depression with acute suicidal thoughts or behaviors. Spravato is FDA-approved for this indication because it works so rapidly. When someone is in acute crisis, waiting weeks for an antidepressant to work isn’t feasible.
Spravato works well for adults across different age groups, though pregnant women and those with certain cardiovascular conditions need special consideration. Your healthcare provider can assess whether you fall into any contraindicated categories. The best candidates are those who are motivated, willing to visit a certified treatment facility twice weekly initially, and open to combining Spravato with an oral antidepressant for optimal results. If you’ve experienced side effects from traditional medications that have prevented you from staying on treatment, Spravato’s different mechanism makes it worth discussing with your doctor.
The Spravato Treatment Process
Receiving Spravato isn’t like popping a pill at home. It requires a specific protocol to ensure your safety and effectiveness of treatment. Your first step is a comprehensive consultation where your healthcare provider assesses your medical history, current medications, and depression severity. During this visit, you’ll discuss your previous treatment attempts, your goals, and any concerns. Once you’re approved, treatment happens in a certified healthcare facility under professional supervision. This isn’t a limitation; it’s a feature. In-clinic administration allows medical staff to monitor you closely and manage any side effects immediately.
For the first four weeks, you typically receive Spravato twice weekly. After that, the frequency usually decreases to once weekly for weeks five through eight, and then continues on a maintenance schedule tailored to your response. Each appointment takes about three to four hours, including the 10 to 15 minutes for the actual nasal spray administration, plus time for monitoring and recovery. You’ll need someone to drive you home because Spravato can cause temporary dizziness, dissociation, or sedation. Many patients feel dramatic relief after their first or second dose, while others experience gradual improvement over several sessions. The key is consistency and patience with the protocol. Some patients describe their first dose as feeling like the fog suddenly lifted, while others describe a slow but steady climb out of the depressive episode.
What About Side Effects?
Like any medication, Spravato carries potential side effects, though many are temporary and manageable. The most common side effects occur during or shortly after administration and include dissociation (feeling disconnected from your body or surroundings), dizziness, sedation, and anxiety. These typically resolve within a few hours. Because Spravato requires in-clinic administration with monitoring, your healthcare team can manage these effects immediately. You’re never navigating these effects alone.
More importantly, Spravato has a distinct advantage over many traditional antidepressants: it causes almost no sexual dysfunction. Less than 1% of Spravato users report treatment-emergent sexual side effects, compared with 20 to 40% of people taking SSRIs. For many patients, sexual dysfunction from antidepressants has been so bothersome that they’ve stopped taking medications altogether, even when those medications were helping their mood. Some have endured years of depression because they couldn’t tolerate the sexual side effects. If sexual dysfunction has been a barrier keeping you from consistent antidepressant use, Spravato sidesteps that problem entirely. Serious side effects are rare when administered properly in a medical setting. Your medical team will monitor blood pressure, heart rate, and consciousness throughout your treatment.
Combining Spravato With Therapy
Medication alone rarely solves depression permanently. Medication works best alongside therapy. Many patients find that Spravato gives them the mental clarity and emotional bandwidth needed to engage meaningfully in psychotherapy. With depression’s weight lifted, you can actually absorb and apply what you learn in therapy sessions. You have the energy to do the work. This combination approach addresses both the neurochemistry of depression and the psychological patterns that maintain it.
At Catalyst Health & Wellness, our integrated model pairs Spravato with experienced therapists who specialize in trauma, anxiety, eating disorders, and psychedelic-assisted approaches. This ensures you’re not just getting symptom relief but building genuine, lasting healing. Our team works collaboratively so your therapy reinforces the neurobiological benefits of Spravato.
Next Steps—Is Spravato Right for You?
The only way to know if Spravato is right for you is to speak with a qualified healthcare provider who understands your full medical picture. If you’ve tried multiple antidepressants without adequate relief, or if you’re struggling with acute suicidal thoughts, Spravato deserves serious consideration. There’s no shame in exploring every option. Depression is a serious condition, and when standard treatments don’t work, having access to science-backed alternatives like Spravato can be life-changing.
Many patients tell us they wish they’d discovered Spravato years earlier. They’ve tried everything else. But Spravato wasn’t available before. Now it is. The key is moving forward with information and professional guidance, and having a treatment team that understands your unique situation. You deserve relief, and relief is possible.
