Spravato® vs. IV Ketamine: Finding the Right Path for Recovery
A complete guide to ketamine infusion therapy. Learn how to prepare, what to expect during treatment, possible side effects, and how to support recovery.
Patients navigating treatment-resistant depression (TRD) often find themselves comparing Spravato® (esketamine) and Intravenous (IV) Ketamine infusions. While both therapies target the same brain receptors to foster neuroplasticity and provide rapid symptom relief, they differ in key ways specifically in how they are administered, their subjective effects, and their overall cost.
At the Ketamine Center of CT (KCC), we believe that understanding these nuances is the first step toward healing. This article examines the latest research and clinical benefits of both Spravato® and IV ketamine to help you make an informed decision alongside your healthcare provider.
This naturally raises important questions:
What Makes Spravato® and Ketamine Similar?
Both Ketamine and Spravato® (esketamine) sessions must occur in monitored clinical settings to ensure patient safety. The primary difference lies in the delivery method: Spravato® is administered as a nasal spray, while ketamine is typically given intravenously (IV).
It is also important to note the regulatory status of these treatments. Spravato® is an FDA-approved medication for Major Depressive Disorder (MDD). In contrast, IV ketamine is FDA-approved as an anesthetic. Using it to treat mental health conditions is considered an “off-label” use a common medical practice where a safe, approved drug is used for a secondary purpose based on clinical evidence.
Intranasal Spravato®
Spravato® delivers a low dose of esketamine through a quick nasal spray. During a typical session, most patients use two to three devices spaced about five minutes apart.
The treatment plan usually starts with sessions twice a week for the first four weeks. After that, you move into a maintenance phase, where sessions happen once every week or two. Because your safety is our priority, each session includes a two-hour monitoring period in our clinic, as some side effects can last for a few hours.
IV Ketamine Infusion
IV Ketamine infusions are delivered directly into the bloodstream through a small IV line. This allow us to provide precise, controlled doses tailored to your needs.
The standard initial protocol involves six treatments over two to three weeks. After this initial phase, many patients transition to maintenance or booster sessions as needed to sustain their progress. Each infusion session lasts between 45 minutes and one hour. Since some side effects may linger for a few hours after the infusion, we ensure you are comfortable and monitored before you head home.
Which Route is Better?
Understanding the technical differences between Spravato® (a nasal spray) and IV Ketamine infusions is essential. While Spravato® is FDA-approved for Major Depressive Disorder (MDD) and often covered by insurance, KCC specializes in IV infusions because they offer the highest level of precision and “bioavailability.”
In a clinical setting, IV delivery ensures that 100% of the medication reaches the bloodstream instantly. Nasal sprays can be less consistent due to factors like nasal congestion or individual anatomy. By using the IV route, Dr. Gino can tailor and adjust the dosage in real-time to meet your specific needs. The best path for your recovery is always determined during a clinical consultation where we review your history and goals.

How do I prepare for a Ketamine infusion session?
It’s recommended to arrive with someone who can accompany you, as you may feel slightly tired after the session. Wearing comfortable clothing can also help make the process easier.
- Arrival
You may receive medication beforehand to help prevent nausea, as some individuals can experience mild discomfort. - Setup
You will be placed in a comfortable and private setting where your vital signs are monitored throughout the session to ensure safety. - Infusion
A small intravenous (IV) line is inserted, typically in the arm or hand. The process is generally well-tolerated and allows the medication to be delivered steadily. - Duration
Sessions typically last around 45 minutes for mood-related treatments, while other conditions may require longer infusion times. - After the Session
Most of the immediate effects wear off shortly after the infusion. However, it’s normal to feel slightly tired or relaxed for a few hours afterward.
In the Days After Your Session
- Take time to reflect
Processing your experience can be valuable. Writing your thoughts down or speaking with a therapist can help you better understand any insights or emotional shifts. - Stay consistent with your care
Ketamine therapy is often most effective when combined with ongoing support, such as therapy, healthy routines, and structured mental health care. - Prioritize rest
Quality sleep allows the brain to process and integrate the effects of the treatment, supporting recovery and overall well-being. - Follow your treatment plan
Multiple sessions are typically recommended to achieve the best results. Staying consistent with your schedule helps build and maintain the therapeutic effects over time.
No solid food for 4 hours before a ketamine infusion. Clear liquids only 2 hours before the infusion.

We specialize in IV Ketamine infusions because they offer 100% bioavailability. Unlike nasal sprays, which can be affected by congestion or individual anatomy, IV delivery ensures the exact dose reaches your bloodstream instantly, allowing for precise medical control.
While the FDA approved Ketamine as an anesthetic, its use for mental health is considered “off-label.” This is a common and legal medical practice where a safe, approved medication is used for a new purpose based on strong clinical evidence.
Conclusion
Both Spravato® and IV Ketamine infusions offer a bridge to hope for those living with treatment-resistant depression. While Spravato® offers the convenience of insurance coverage for many, it is a standardized treatment.
At the Ketamine Center of CT, we specialize in IV Ketamine infusions because we believe in the power of precision. By using the “racemic” form of ketamine and delivering it intravenously, Dr. Gino can ensure 100% bioavailability and adjust your treatment in real-time based on your unique response.
The best route isn’t just about convenience it’s about what works best for your brain. We invite you to schedule a consultation to discuss how our personalized IV protocols can help you reclaim your life.
