Spravato: Side Effects and What to Do About Them

Spravato can be a big deal for people with treatment-resistant depression. It can also come with side effects that make a treatment day feel less like a spa visit and more like your brain accidentally sat on the TV remote. The good news is that many Spravato side effects are short-lived, expected, and manageable when you know what is normal, what is annoying, and what deserves a fast call to your care team.

If you are researching Spravato side effects, you are probably asking two questions at once: “What might happen?” and “What on earth am I supposed to do if it does?” This guide answers both. We will walk through common Spravato side effects, how they usually show up, how to prepare for treatment days, and when a symptom crosses the line from inconvenient to urgent.

What Is Spravato, Exactly?

Spravato is the brand name for esketamine nasal spray. It is used in adults with treatment-resistant depression, and it may be used alone or with an oral antidepressant for that purpose. It is also used with an oral antidepressant for depressive symptoms in adults with major depressive disorder who have acute suicidal thoughts or behavior. Unlike a pill you pick up and take at home, Spravato is given in a certified medical setting under supervision.

That supervised setting is not a dramatic marketing flourish. It exists because Spravato can cause temporary but important side effects such as sedation, dissociation, increases in blood pressure, and breathing-related problems. Patients are monitored after each session, which is why treatment day comes with a built-in waiting period and a firm “you are not driving yourself home” rule. Spravato is powerful, helpful for some people, and absolutely not a casual sniff-and-go situation.

Why Side Effects Get So Much Attention

Spravato has boxed warnings for sedation, dissociation, abuse and misuse, and suicidal thoughts and behaviors associated with antidepressants. It is also part of a REMS program, which is short for Risk Evaluation and Mitigation Strategy. In plain English, that means the medication has enough important safety concerns that the FDA requires extra rules around how it is prescribed and administered.

That sounds intense, but it is also reassuring. The monitoring process is there because clinicians know what they are looking for. Most side effects happen soon after a dose and often improve the same day. The goal is not to scare people away from treatment. The goal is to make treatment safer, more predictable, and a lot less mysterious.

Common Spravato Side Effects and What to Do About Them

1. Dissociation or Feeling “Detached”

Dissociation is one of the most talked-about Spravato side effects. Some people describe it as feeling floaty, unreal, emotionally distant, dreamlike, or disconnected from time and space. Others say it feels like being tipsy without asking for the cocktail menu. It can be unsettling if you are not expecting it, especially during early sessions.

What to do about it: Do not fight it like you are arm-wrestling the universe. Stay seated or reclined, keep stimulation low, and tell the staff exactly what you are feeling. A quiet room, dim lights, slow breathing, and reassurance from the care team often help. Many people find it useful to avoid deep phone scrolling, stressful texts, or trying to “power through” a productive work session in the clinic. This is not the hour to answer emails titled “Quick question.”

If dissociation is severe, frightening, or lasts longer than expected, your clinician may adjust the dose or monitor you longer. If you have a history of psychosis or severe perceptual symptoms, your provider should already be weighing those risks carefully.

2. Sedation and Sleepiness

Feeling sleepy, slowed down, or mentally foggy is another common Spravato side effect. Some people feel heavily relaxed. Others feel like their brain has switched to low-power mode. Because alertness and coordination can drop, patients are monitored after dosing and told not to drive or operate machinery until the next day after a restful sleep.

What to do about it: Plan your day around being done. Not “done but maybe I can still run errands.” Done. Arrange a ride home, clear your schedule, and wear comfortable clothes. If sedation feels stronger than usual, tell your clinician. Combining Spravato with alcohol, recreational drugs, or other sedating substances can make this worse, so follow your prescriber’s instructions closely about other medications and what to avoid.

3. Dizziness or Vertigo

Dizziness is common, and some people also report vertigo or a spinning sensation. This is one reason treatment centers are picky about keeping you seated during observation. Standing up too fast is a terrible time for a surprise carousel impression.

What to do about it: Change positions slowly, ask for help before standing, and keep your body as steady as possible until the sensation passes. If you are prone to motion sickness, mention that before treatment. If dizziness continues beyond the clinic, worsens, or comes with chest pain, fainting, or shortness of breath, contact your provider promptly.

4. Nausea and Vomiting

Nausea is another common complaint, and vomiting can happen too. This is why patients are usually told to avoid food for at least two hours before treatment and liquids for at least 30 minutes beforehand. A full stomach and a dizzy brain are not always a peaceful combination.

What to do about it: Follow the pre-treatment eating and drinking instructions carefully. After treatment, ask your clinician when it is okay to sip water or have a bland snack. Ginger chews, crackers, toast, or simple foods may be easier than anything greasy, spicy, or heroic. If nausea is a repeat performance at multiple sessions, ask whether an anti-nausea strategy makes sense for you.

5. Headache

Headache can happen during or after a session. Sometimes it is tied to temporary blood pressure changes, stress, dehydration, or just your nervous system generally filing a noisy complaint.

What to do about it: Let the clinic know when the headache starts and how strong it feels. Rest, hydration after your observation period, and your clinician’s advice about over-the-counter pain relief may help. A mild headache may be more annoying than dangerous, but a severe headache, especially with chest pain, vision changes, confusion, or very high blood pressure, should not be brushed off.

6. Increased Blood Pressure

Spravato can raise blood pressure for a while after dosing. That is why blood pressure checks are part of the routine before and after treatment. For many people, the increase is temporary. For some, especially those with cardiovascular or cerebrovascular risks, it deserves extra attention.

What to do about it: Be honest about your medical history, especially uncontrolled high blood pressure, aneurysm history, heart disease, stroke risk, or severe headaches. On treatment day, avoid unnecessary stress, and let staff know right away if you get pounding headaches, chest pain, shortness of breath, or unusual vision changes. If you already monitor your blood pressure at home, your clinician may want you to keep an eye on it between visits.

7. Anxiety, Restlessness, or Feeling Strange

Some people feel anxious, restless, or emotionally odd after a dose. Others report a “feeling drunk” sensation, unusual calm, or a brief euphoric mood. Spravato can affect perception, mood, and body awareness in ways that feel weird before they feel familiar.

What to do about it: Name the feeling instead of silently panicking through it. Tell the care team whether you feel agitated, scared, overstimulated, or unusually elevated. Headphones with calm music, an eye mask, grounding exercises, and simple breathing techniques can help take the edge off. If the mood change feels extreme, lasts beyond the treatment window, or affects your behavior, report it right away.

8. Numbness, Reduced Sensation, or “Weird Body” Feelings

Some people experience numbness, tingling, or altered body sensations. This can be part of the broader dissociative picture. It is not always dangerous, but it can feel deeply strange if nobody warned you ahead of time.

What to do about it: Stay calm, stay seated, and describe the symptom clearly. Is it tingling? Heaviness? Reduced sensation? One side or both? Temporary body weirdness may happen, but anything one-sided, sudden, or paired with weakness, slurred speech, or severe confusion needs immediate medical evaluation.

Less Common but More Serious Problems

Now for the part nobody loves but everybody needs. Certain Spravato side effects are less common yet more important. These include breathing problems, fainting, severe blood pressure spikes, allergic reactions, persistent confusion, and mood symptoms that worsen instead of improve.

Call your clinician or seek urgent medical attention right away if you notice trouble breathing, blue lips, severe chest pain, severe headache, passing out, intense confusion that does not improve, signs of an allergic reaction, or a dramatic worsening of depression, agitation, or suicidal thoughts. If something feels way outside your usual pattern, trust that instinct and say so. This is not the medicine to “tough out in silence.”

How to Make Spravato Treatment Days Easier

A smoother treatment day often means fewer side-effect surprises. Try these practical strategies:

• Follow food and liquid instructions exactly.
• Arrange a reliable ride home every single time.
• Wear comfortable clothes and skip anything complicated, restrictive, or office-boardroom ambitious.
• Bring a calming playlist, eye mask, or light blanket if your clinic allows it.
• Tell your provider about every medication, supplement, and substance you use.
• Do not plan major work, arguments, shopping sprees, or life decisions after treatment.
• Track side effects in a simple note on your phone so you can report patterns across sessions.

Also, remember that the first few sessions may feel different from later ones. Some people notice the side effects most strongly at the beginning and then find them more predictable over time. Others need dose adjustments or extra support to find the right balance between benefit and tolerability.

When to Talk to Your Prescriber About Changing the Plan

It is worth speaking up if your side effects are intense, your recovery after treatment takes too long, or you feel so wiped out that the treatment day knocks out the next day too. Your prescriber may consider dose changes, spacing adjustments, longer observation, or supportive strategies for nausea, anxiety, or headache.

Do not assume suffering is the admission fee for treatment. The goal is not to win a stoicism contest. The goal is to get meaningful relief from depression while keeping the side effects manageable and safe.

Experiences Related to Spravato: What Many Patients Notice in Real Life

Many people researching Spravato want more than a dry list of side effects. They want to know what the experience is actually like. While no two patients have the exact same story, some patterns come up again and again.

First, the anticipation can be almost as intense as the session itself. A lot of patients arrive wondering whether they will feel nothing, feel better, or feel like their brain has decided to visit another ZIP code for a while. That uncertainty is normal. For some, the first session feels strange mainly because it is unfamiliar. The room is quiet, the staff is observant, and there is suddenly a lot of attention on things most people never think about, like how “attached” they feel to reality on a scale from one to ten.

During treatment, many patients report a short window where things feel distinctly off. Time may seem slower. Sounds may feel farther away. The body may feel heavy, floaty, or mildly disconnected. Some people describe it as being awake inside a dream. Others say it feels like being extremely relaxed and mildly confused at the same time, which is admittedly not a sentence anyone aims to say about their Tuesday. For many, that odd feeling peaks fairly early and then gradually fades during the observation period.

Nausea and dizziness often shape the “texture” of the day more than people expect. Even when they are not severe, they can make patients feel fragile, tired, and less interested in doing much afterward. This is why experienced patients often become treatment-day minimalists. They stop trying to squeeze in errands, social plans, or ambitious goals after a session. The smart move is usually to head home, rest, hydrate when allowed, and let the day be simple.

Another common experience is that side effects do not always match the emotional result. A person may feel physically odd yet mentally hopeful. Someone else may feel mentally clearer while still dealing with fatigue or a headache. That mismatch can be confusing at first. Improvement in depression does not always arrive wrapped in a perfect, symptom-free bow. Sometimes the emotional relief and the treatment-day inconvenience show up together, and patients have to decide with their clinicians whether the tradeoff is worth it.

Over multiple sessions, many people say the process becomes more predictable. They learn what to wear, what to eat beforehand, what kind of ride home feels best, and how much rest they will need later. They also learn their own pattern. Maybe session one brings more dissociation, while later sessions bring more sleepiness. Maybe blood pressure is the main issue, or maybe nausea steals the show. Once that pattern is visible, patients and providers can respond more strategically instead of guessing.

What patients often appreciate most is honest preparation. Side effects are easier to tolerate when they are expected, monitored, and explained. In that sense, the Spravato experience is often less about being fearless and more about being informed. Knowing that strange does not always mean dangerous, and knowing exactly when strange does mean “tell the nurse right now,” can make the whole process feel much less intimidating.

Final Thoughts

Spravato side effects are real, but so is the value of knowing how to handle them. The most common issues, such as dissociation, dizziness, nausea, sleepiness, headache, and temporary blood pressure increases, are often manageable when treatment happens in the right setting and patients know what to expect. Preparation, communication, and careful monitoring do a lot of the heavy lifting.

If you are considering Spravato or already receiving it, the best move is to treat side effects as information, not personal failure. Tell your clinician what happened, when it happened, and how intense it felt. The more specific you are, the easier it is to adjust the plan. Depression treatment is hard enough without adding mystery. A clearer map makes the road less scary.
