Spravato (Generic Esketamine): Complete Medication Guide
Key Takeaways
Esketamine is a nasal spray medication used to treat treatment-resistant depression in adults when combined with oral antidepressants.
It works by affecting brain chemicals related to mood and may provide relief faster than traditional antidepressants.
Common side effects include dizziness, nausea, and dissociation, which usually improve over time.
Esketamine requires supervised administration in a medical setting due to its potential for abuse and serious side effects.
This medication is typically reserved for people who haven't responded well to other depression treatments.
Spravato (Generic Esketamine) Overview
Esketamine is the active ingredient in Spravato, a nasal spray medication approved to treat treatment-resistant depression (TRD) in adults. It's a derivative of ketamine, an anesthetic that has shown promise in mental health care. Unlike traditional antidepressants that may take weeks to work, esketamine may help some people feel better more quickly.
This medication works by targeting glutamate receptors in the brain—a different approach than most other antidepressants. Glutamate is a neurotransmitter involved in mood regulation and brain function. By modulating glutamate activity, esketamine may help restore mood balance in people whose depression hasn't improved with standard treatments.
Esketamine is always given alongside an oral antidepressant. It's administered in a healthcare provider's office under direct supervision, where you'll remain for at least two hours after taking it. Understanding how this medication works and what to expect can help you make informed decisions about your treatment options. If you're exploring medication choices, learning about generic vs brand name drugs may help you understand your options better.

Side Effects
Esketamine is generally well-tolerated, but like all medications, it can cause side effects. Most side effects appear shortly after administration and improve within a few hours. Understanding what to expect helps you prepare and manage your treatment experience.
Common Side Effects
Dizziness and lightheadedness — Often occurs after administration and typically resolves within a few hours as the medication wears off.
Nausea and vomiting — May happen during or shortly after dosing; eating a light meal beforehand may help.
Dissociation — A feeling of detachment from your body or surroundings; this is expected and temporary, lasting 1–2 hours.
Drowsiness and sedation — You may feel sleepy or tired; plan to rest after your appointment and avoid driving.
Headache — Mild to moderate headaches may occur; over-the-counter pain relievers may help if approved by your doctor.
Difficulty concentrating — Temporary cognitive effects that resolve as the medication leaves your system.
Serious Side Effects
Increased blood pressure — Esketamine may raise blood pressure during and after administration; your doctor will monitor this closely.
Suicidal thoughts or behaviors — Some people experience worsening depression or new suicidal thoughts, especially early in treatment; report any changes immediately.
Severe dissociation or confusion — While mild dissociation is expected, severe or prolonged confusion requires medical attention.
Abuse potential — Esketamine has potential for misuse; it's only given in supervised medical settings to prevent this.
Addiction risk — Long-term use may carry psychological dependence risks in some individuals; discuss duration of treatment with your provider.
When to Seek Medical Attention
Contact your healthcare provider right away if you experience suicidal thoughts, severe confusion that doesn't resolve within hours, extreme blood pressure changes, or signs of an allergic reaction such as difficulty breathing or severe rash. If you feel unsafe after your appointment or have thoughts of harming yourself, call 911 or go to the nearest emergency room.
Most people can manage their appointments safely with proper medical supervision. Your treatment team monitors your vital signs and mental state throughout your visit to catch any concerns early. Don't hesitate to communicate any worries to your healthcare provider before, during, or after treatment.

Drug Interactions
Esketamine can interact with other medications and substances. These interactions may reduce effectiveness, increase side effects, or create safety risks. Always inform your healthcare provider about all medications, supplements, and substances you use.
Alcohol and Sedatives
Combining esketamine with alcohol, benzodiazepines, or other sedating medications increases drowsiness, dizziness, and dissociation. Avoid alcohol for at least 24 hours before and after your appointment, and discuss all sedative use with your doctor.
Blood Pressure Medications
Esketamine raises blood pressure during administration. If you take medications for hypertension, your doctor may need to adjust dosing or monitor your blood pressure more closely during treatment.
Stimulant Medications
Stimulants (including some ADHD medications and decongestants) combined with esketamine may further elevate blood pressure. Let your doctor know about all stimulant use before starting esketamine.
Opioid Medications
Using esketamine with opioids increases the risk of severe sedation, respiratory depression, and overdose. Your doctor will carefully assess whether this combination is safe for you.
Monoamine Oxidase Inhibitors (MAOIs)
Taking esketamine with MAOI antidepressants is generally not recommended due to increased risk of serotonin syndrome. Discuss all antidepressants with your doctor before starting esketamine.
Anesthetics and Dissociative Drugs
Combining esketamine with other anesthetics or dissociative substances (like PCP or dextromethorphan) increases the risk of serious side effects and overdose.
