A New Path to Mental Clarity
A Different Mechanism of Action
Roughly one in three adults with major depressive disorder does not respond to two or more traditional oral antidepressants. If that describes you, you may feel exhausted, hopeless, or stuck in a cycle of trial-and-error prescriptions that never fully lift the heaviness. Many patients we see have tried SSRIs, SNRIs, atypicals, and augmentation strategies for months or years. The depression persists, functioning at work and home becomes harder, and in some cases acute suicidal thoughts emerge despite consistent medication adherence.
Spravato works through a fundamentally different mechanism than oral antidepressants. As an NMDA receptor antagonist, esketamine rapidly modulates glutamate signaling, the brain's primary excitatory neurotransmitter system. This can produce noticeable mood improvement within hours to days rather than the 4-8 weeks typical of SSRIs. Combined with an oral antidepressant and delivered in our certified clinic, Spravato offers a new option when other treatments have not worked, with patients monitored closely for safety throughout every session.
The Science of NMDA Modulation
Spravato is the brand name for esketamine, an FDA-approved nasal spray used to treat adults with treatment-resistant depression (approved 2019) and major depressive disorder with acute suicidal ideation or behavior (approved 2020). It is the S-enantiomer of ketamine and is administered only alongside a newly prescribed oral antidepressant. According to the FDA approval for esketamine, Spravato is dispensed exclusively through certified healthcare settings under a Risk Evaluation and Mitigation Strategy (REMS) program.
Spravato targets the N-methyl-D-aspartate (NMDA) receptor, a glutamate receptor involved in synaptic plasticity and mood regulation. By briefly blocking NMDA activity, esketamine triggers a cascade that increases brain-derived neurotrophic factor (BDNF) and promotes rapid synaptic repair in regions affected by chronic depression. Phase 3 trials (Popova 2019) reported a significantly greater reduction in depressive symptoms compared with placebo plus oral antidepressant as early as 24 hours after the first dose.
You self-administer the nasal spray under clinical supervision in our Pembroke Pines office. After dosing, you relax in a private, calming treatment suite while our team monitors blood pressure, sedation, and any dissociative effects for a full two hours before discharge.
Most patients begin noticing mood improvement within the first 1-2 weeks of the induction phase. Remission rates at four weeks range from 27 to 53 percent in clinical trials. Ongoing maintenance dosing, guided by your psychiatric evaluation and medication management plan, helps sustain response long-term.

Finding Your Best Treatment Fit
Spravato is specifically indicated for adults whose depression has not responded adequately to conventional oral antidepressants. According to guidance from the National Institute of Mental Health, roughly a third of patients with major depressive disorder experience treatment-resistant symptoms and may benefit from novel mechanisms.
If you are unsure whether Spravato is right for you, consider discussing alternatives like TMS therapy, another FDA-approved option for treatment-resistant depression. Our team will review your full history and recommend the safest, most effective path.

What to Know
The most frequently reported effects during or after treatment include dissociation (feeling detached from surroundings), mild sedation or drowsiness, dizziness, nausea, transient blood pressure elevation, vertigo, and headache. These typically peak within 40 minutes of dosing and resolve during the 2-hour monitoring period.
Less common but serious risks include significant hypertensive episodes, respiratory depression, and rare reports of bladder irritation with repeated high-dose ketamine-class exposure. Abuse and dependence are also cited as boxed warnings, which is why Spravato is distributed exclusively under the REMS program.
Spravato received FDA approval in 2019 for treatment-resistant depression and in 2020 for MDD with acute suicidal ideation. The Spravato prescribing information requires every dose to be administered in a certified healthcare setting with post-dose monitoring. All six of Dr. Carmona's clinicians complete ongoing REMS training to minimize risk and intervene immediately if adverse events occur.
Spravato session costs in the Broward County market typically range from $600 to $900 per treatment before insurance, depending on dose (56 mg or 84 mg) and whether you are in the induction or maintenance phase. Most major commercial insurance plans and Medicare cover Spravato when medical necessity criteria are met, since it is FDA-approved. Exact out-of-pocket pricing will be discussed during your consultation based on your plan, dose, and frequency.

Your Questions Answered
Spravato (esketamine) is an FDA-approved nasal spray for adults with treatment-resistant depression and major depressive disorder with acute suicidal ideation. It is always prescribed alongside a new oral antidepressant and delivered in a REMS-certified clinic.
Spravato blocks NMDA receptors, modulating the glutamate system rather than serotonin. This stimulates rapid synaptic repair and BDNF release, producing mood improvement far faster than SSRIs, which act on serotonin and take 4 to 8 weeks.
Most commercial insurance plans and Medicare cover Spravato when medical necessity is documented, since it is FDA-approved. R&C Psychiatry's billing team handles prior authorization and REMS paperwork. Janssen CarePath also offers copay assistance for eligible commercial plans.
Spravato is the purified S-enantiomer of ketamine, delivered as a nasal spray with FDA approval and REMS oversight. IV ketamine is the racemic form used off-label. R&C offers Spravato only, and we can also discuss TMS therapy if you prefer a non-medication option.
Most patients describe mild dissociation, a floating or detached sensation, within 20 to 40 minutes of dosing. Drowsiness, dizziness, and slight blood pressure elevation are common. These effects resolve during the 2-hour monitored observation before you go home.
Phase 3 trials (Popova 2019, Fedgchin 2019) showed Spravato combined with a new oral antidepressant significantly reduced depression scores within 24 hours to 4 weeks compared with placebo plus antidepressant. Remission rates at 4 weeks ranged from 27 to 53 percent.
Many patients notice improvement within the first 24 hours to 1 week of induction dosing, with peak response typically reached by week 4. Maintenance sessions every 1 to 2 weeks help sustain response long-term under Dr. Carmona's supervision.
