Spravato treatment takes place under clinical supervision because the experience can affect alertness, perception, balance, and blood pressure. Knowing what may happen can help you communicate clearly with your care team and recognize when a symptom needs attention.
Spravato side effects can include temporary dissociation, dizziness, nausea, sleepiness, vertigo, anxiety, vomiting, and increased blood pressure. Many effects are assessed during the session and observation period, but severe or persistent symptoms after leaving the facility require immediate contact with your provider. If you or someone with you is in immediate danger or experiencing a mental health crisis, call or text 988, or text HOME to 741741.
Relief Mental Health clinicians monitor patients during and after administration and explain what to expect. This guide separates common effects from urgent warning signs, beginning with the symptoms patients most often notice. For broader background, read our Spravato overview.

Most Common Spravato Side Effects
Spravato affects people differently. Some patients notice only mild changes, while others experience several sensations during or shortly after a session.
Understanding the possible effects can make it easier to describe what you are feeling and ask for support from your clinical team. The official Spravato prescribing information lists the following among the most common side effects:
- Dissociation, or feeling detached from your surroundings or usual sense of self.
- Dizziness, vertigo, or a feeling that the room is spinning.
- Nausea and, sometimes, vomiting.
- Sedation, sleepiness, lethargy, or sluggishness.
- Anxiety or feeling intoxicated, sometimes described as feeling drunk.
- Decreased sensation, also called hypoesthesia.
| Effect. | What it may feel like. | What to do. |
|---|---|---|
| Dissociation. | Feeling detached from your body. | Tell the clinical team. |
| Dizziness or vertigo. | Feeling unsteady or as if the room is spinning. | Remain seated. |
| Nausea or vomiting. | Stomach discomfort or feeling sick. | Report it during observation. |
| Sedation. | Sleepiness or sluggishness. | Allow the team to monitor alertness. |
Dissociation and changes in perception
Dissociation can feel unfamiliar or unsettling. You may feel separated from your body, surroundings, thoughts, or sense of time. Feeling intoxicated can occur alongside these changes. These sensations are important to report, even if they seem manageable, because your provider can help you stay oriented and comfortable while you are being observed.
Dizziness, vertigo, and decreased sensation
Dizziness and vertigo may make it difficult to stand or walk safely. Decreased sensation can mean that parts of your body feel less sensitive than usual. For these reasons, your care team observes you during the session rather than asking you to leave immediately after administration. Move slowly, follow staff instructions, and tell them if the sensation becomes stronger, continues, or makes you feel unsafe.
Nausea, sedation, and emotional effects
Nausea and vomiting are frequently observed with Spravato. Sedation means sleepiness or drowsiness, and lethargy may leave you feeling sluggish after the initial administration. Anxiety can also occur, even when you expected to feel calm. Side effects can overlap, and the same symptom may feel different from one session to the next. Your clinical team can assess the pattern, discuss what you are experiencing, and determine whether additional evaluation is needed.
Do not minimize a severe or persistent symptom after leaving the facility. Contact your healthcare provider immediately if concerning effects continue or worsen. Ongoing communication helps your provider evaluate your response and keep treatment focused on your safety.
How Long Do Spravato Side Effects Last?
Spravato side effects may begin during administration or shortly afterward. Some people notice changes in alertness, balance, perception, or stomach comfort soon after using the nasal spray. Others may experience symptoms differently. There is no single recovery timeline that applies to every patient, so your clinical team evaluates how you are responding rather than relying on the clock alone.
Because effects can develop around the time of administration, the observation period is an important part of a Spravato session. The FDA prescribing information states that patients must be monitored by a healthcare provider for at least two hours after administration. This does not mean every person will feel exactly the same at the two-hour mark. It means the provider has time to assess your symptoms, alertness, blood pressure, and overall stability before deciding whether you are ready to leave.
Common effects may include dissociation, dizziness, nausea, sedation, vertigo, anxiety, lethargy, or a feeling of reduced sensation. Nausea and vomiting can occur, while sedation may feel like sleepiness or drowsiness. These symptoms are assessed during the visit so you can describe what you are experiencing and staff can respond appropriately. Tell the team promptly if a sensation feels intense, changes suddenly, or makes you feel unsafe.
Some people may continue to feel tired, unsteady, or less alert after leaving the clinic. Follow your provider’s instructions about the remainder of the day, and do not assume that a typical experience guarantees the same response at a later session. Your provider determines when you are ready to leave based on your individual recovery, not just the minimum observation period.
If a side effect is severe or persists after you leave the treatment facility, contact your healthcare provider immediately. Sharing what you felt, when it began, and how long it continued helps your clinical team make safer decisions about future sessions.
Serious Side Effects of Spravato to Know
Many Spravato effects are temporary and monitored in the clinic. Still, it is important to know which symptoms require prompt attention. Your care team should explain what to expect, observe you during and after treatment, and help you decide what to do if symptoms continue after you leave.
When symptoms need urgent attention
Contact your provider immediately if a side effect feels severe, lasts longer than expected, or becomes worse after you return home. The prescribing information specifically advises patients to seek immediate medical guidance for persistent or severe effects after leaving the treatment facility. Do not wait for a routine follow-up if you are worried about a new or unusual symptom. The FDA-approved prescribing information provides additional safety details.
Seek emergency help for an emergency, such as difficulty breathing, being unusually difficult to wake, or becoming unresponsive. Severe sedation can go beyond ordinary sleepiness. If someone cannot stay awake, respond normally, or breathe comfortably, call emergency services rather than attempting to manage the situation alone.
Blood pressure and dissociation concerns
Spravato can cause a temporary increase in blood pressure, which is one reason vital signs are checked during the visit. A severe headache, chest discomfort, shortness of breath, confusion, weakness, vision changes, or other alarming symptoms should be reported to clinical staff right away. If these symptoms appear after leaving, contact your provider and seek emergency care when appropriate.
Dissociation can involve feeling detached from your body or surroundings. A mild, short-lived change in perception may occur during treatment, but severe disorientation, panic that does not settle. Inability to communicate safely, or a persistent sense of unreality deserves immediate clinical attention. Tell staff exactly what you are experiencing. Clear communication helps them distinguish an expected temporary effect from a problem requiring further evaluation.
Misuse risk deserves honest discussion
Spravato has the potential for misuse and abuse. This does not mean that misuse will occur, but it is an important safety consideration. Use the medication only as directed by your clinical team, and discuss any history of substance misuse. Changes in cravings, or concerns about taking it outside the prescribed setting. Ongoing assessment helps your provider determine whether treatment remains appropriate and safe.
Do not minimize symptoms because you are unsure whether they are serious. Your provider would rather hear about a concern early and help you assess it than have you wait while symptoms worsen.
How Clinical Monitoring Reduces Spravato Side Effect Risk
Spravato is not taken independently at home. The patient self-administers the nasal spray under the direct supervision of a healthcare provider in a certified clinic. This supervised setting gives the clinical team an opportunity to notice changes, answer questions, and respond promptly if a symptom becomes uncomfortable or concerning. The FDA prescribing information describes the most common side effects and the need for monitoring during and after administration.
Supervised administration and symptom checks
Before treatment, tell your provider about your current medications, health history, and any symptoms you are experiencing. That information helps the team understand your individual risk and decide what should be watched most closely. During the session, staff can ask how you feel and look for changes such as dissociation, dizziness, nausea, sedation, anxiety, vertigo, decreased sensation, or a feeling of intoxication. These effects can feel unfamiliar, but communicating them gives your care team useful information rather than leaving you to manage them alone.
Monitoring also includes observing how you respond emotionally and physically. If you feel detached from your surroundings, unusually sleepy, nauseated, unsteady, or distressed, let the staff know. Your clinical team can assess the symptom in context and provide appropriate support. Do not minimize a symptom because you assume it is expected, and do not hesitate to report a change that feels different from what was explained to you.
Blood-pressure checks and post-dose observation
Spravato can cause a temporary increase in blood pressure. For that reason, clinical staff check blood pressure as part of the safety process and continue watching for symptoms that may require attention. The FDA label states that patients must be monitored by a healthcare provider for at least two hours after administration. Observation is not simply waiting for a clock to run out. It allows the team to reassess alertness, comfort, blood pressure, and overall stability before you leave.
At Relief Mental Health, monitoring during and after administration is a key clinical safety requirement. The team explains common Spravato treatment monitoring, oversees the observation period, and uses ongoing assessment to help determine whether care remains appropriate and safe. No monitoring process can guarantee that side effects will not occur, but supervised care creates a structured place to identify concerns and respond to them. If severe or persistent symptoms develop after you leave, contact your healthcare provider immediately.
When to Contact Your Provider About Spravato Side Effects
Your clinical team should know how you feel during and after a Spravato session. Many effects are assessed while you remain at the clinic, but symptoms that persist, worsen, or feel unusual after you leave deserve a call. Do not wait for a scheduled appointment if you are concerned about a reaction.
Contact your provider promptly if you:
- Continue to feel severely sedated, confused, detached, dizzy, or unsteady after returning home.
- Have nausea or vomiting that does not improve, or symptoms that are becoming more intense rather than less noticeable.
- Notice unusual symptoms that were not discussed with your care team before treatment.
- Feel unwell after leaving the clinic and are unsure whether what you are experiencing is expected.
- Have concerns about a blood-pressure change or another symptom your provider told you to watch for.
The FDA-approved prescribing information advises patients to contact a healthcare provider immediately for persistent or severe side effects after leaving the treatment facility. Your provider can help determine whether you need additional evaluation, a change in your care plan, or emergency assistance. Do not drive yourself while you are experiencing significant sedation, dissociation, dizziness, or impaired attention.
Know when to seek emergency help
Call 911 or your local emergency number for an immediate, severe medical emergency. Examples include trouble breathing, loss of consciousness, a seizure, severe chest pain, or an inability to stay awake. Emergency services are the right choice when you may be in immediate danger. You can also contact your provider as soon as it is safe, but do not delay emergency care while waiting for a callback.
Share health information before treatment
Before beginning treatment, tell your clinical team about every current diagnosis, medication, supplement, and relevant part of your health history. Include changes since your last visit, even if they seem unrelated. Accurate information helps your provider assess potential risks, prepare for possible side effects, and decide what monitoring you may need.
During each session, report symptoms as soon as they occur rather than trying to manage them silently. Relief Mental Health’s clinical staff can explain what they are observing and help you understand the next step. Ongoing communication gives your care team the information needed to keep evaluating whether treatment remains appropriate and safe for you.
Preparing for a Spravato Session With Your Care Team
Preparing for treatment is an opportunity to make your care more individualized and help your clinical team plan for your safety. Before a session, share an updated list of every prescription medication, over-the-counter product, and supplement you take. Include recent changes, allergies, and any prior reactions to medications or nasal treatments. Tell your provider about your current diagnoses and relevant health history, even if a detail seems unrelated to depression.
Questions to discuss before treatment
Ask what you may notice during and after administration, including changes in alertness, dizziness, nausea, dissociation, anxiety, or sensation. You can also ask how the clinic monitors blood pressure and symptoms, how long observation generally lasts, and whom to contact if you feel unwell after leaving. Your provider can explain which instructions apply to your individual treatment plan rather than relying on general information about Spravato side effects.
- What symptoms should I report immediately during the session?
- How will we decide whether a side effect needs additional evaluation?
- What should I arrange for the rest of the day after treatment?
- What changes in my medications, sleep, mood, or health should I report before my next visit?
Plan for observation and recovery
Spravato is self-administered under direct healthcare supervision, and the clinical team observes patients during and after treatment. Follow the clinic’s instructions about transportation, driving, work, childcare, and other activities after a session. These are practical safety arrangements, not a sign that every patient will experience the same effects. Plan a quiet period afterward and make sure you know how to reach your care team if symptoms are severe or persistent.
Track symptoms and participate in decisions
Keep brief notes about your mood, sleep, medications, and any symptoms you notice between visits. Record when a symptom began, how long it lasted, and whether anything helped. Bring these notes to your appointments. They give your provider a clearer picture than trying to remember every detail later and support ongoing evaluation of whether treatment remains appropriate and safe. Shared decision-making means telling your team what you are experiencing, asking for explanations, and discussing concerns before agreeing to continue or adjust your care.
- Note the symptom and when it began.
- Tell your care team what changed and how long it lasted.
- Follow the individualized instructions your provider gives you.
