What Does Ketamine Therapy Feel Like?

Maybe it’s your first time trying ketamine therapy for depression. Or maybe, you’re seriously considering it and are curious about the process. Either way, you may be wondering, “What does ketamine feel like?” While treatment can affect everyone differently, there’s a general idea of what you can expect during and after your ketamine therapy. When it comes to ketamine for depression, there are two main treatment methods: intravenous (IV) ketamine therapy and esketamine nasal spray. Each of these treatments can have a slightly different effect on the body.


What Does Ketamine Feel Like?


During a ketamine injection, you may feel dizzy or disconnected from your surroundings, almost as though you are floating. Your mind may wander to strange, dreamlike places, and you may feel deeply relaxed but awake. You may also feel warm, groggy, and nauseated. Some patients vomit during or after IV ketamine therapy. If you routinely get sick during car rides or while taking new medications, then mention that to your ketamine provider. 


The first dose may affect you the most and produce “trippy” effects, but as your body gets used to the ketamine during subsequent injections, you may feel less drastically different during treatment. Some people may not feel much different from usual, even during their first treatment.


Ketamine can affect memory, and you may not remember much about your ketamine treatments after you finish them. Think of how it feels to wake up after a vivid dream. Even if you experienced a good or interesting dream, the details seem to slip away before you’re fully awake, leaving you with a blurry memory of your time during treatment.


A standard dose of ketamine for depression is 0.5 mg/kg over 40 minutes. Ketamine IV therapy providers may begin at a lower or higher dose and run the IV for longer or shorter, depending on your symptoms and what they feel is best. Ketamine IV therapy isn’t FDA-approved for depression, which is why there’s no official protocol for dosage. 


You’ll have a needle inserted in your arm for the duration of your ketamine IV injection anywhere from approximately 40 minutes or an hour. Since most ketamine IV patients return for multiple treatments per week during the beginning of a treatment plan, your injection site may become sore. 


After the IV is removed, you’ll remain at the center for observation until your provider determines that it’s safe for you to be released. 

What Does Esketamine Nasal Spray Feel Like?

Esketamine nasal spray can also make you feel dizzy, profoundly relaxed, and dissociated from the space around you. Instead of an IV injection, your provider will show you how to spray the esketamine in your nose. The spray may drip down the back of your throat, and it might leave you with a metallic taste for a while..


Some people have shared feeling only minor symptoms in the hours after an esketamine nasal spray treatment, while others report feeling symptoms more strongly. Regardless of how you feel, your SPRAVATO® treatment center must be certified by the SPRAVATO® Risk Evaluation and Management Strategy (REMS) program, and each center must follow the appropriate protocol set out by the FDA and REMS. 


This means that even if they don’t feel too drowsy or altered, patients must remain at the treatment center for at least two hours after taking SPRAVATO®. During the 2-hour period, the clinic staff observes each patient’s reaction to the medication and helps ensure a safe treatment experience. 


After each patient is cleared to leave, they must be picked up and driven home by someone else. This safety precaution is in place because esketamine can make you feel sleepy and drowsy for the remainder of the day. Patients should not drive or operate any machinery until the next day.


How Do You Feel After Ketamine?

Regardless of which type of ketamine therapy you take, the aftereffects can be similar: you might feel drowsy, slightly drunk, and a little bit “out of it.” Therefore, it’s a good idea to block time to rest and relax after leaving the REMS site. 


After a full night’s rest, however, these side effects should be gone. The benefits to your mind, however, are just beginning. Some patients report feeling improvement in depression symptoms just hours after esketamine treatment. Ketamine IV therapy can also lead to rapid improvement of symptoms. Other patients find that it takes a few treatments to feel better. 


Because the induction period for both ketamine IV and SPRAVATO® means you’re getting two treatments per week, there’s a good chance you’ll feel better just one to two weeks after starting ketamine treatment. To help assess how well the medication is working, SPRAVATO® patients are given depression scales to fill out before each session. 


Esketamine Treatment at Greenbrook TMS


Unlike IV ketamine for depression, esketamine nasal spray is FDA approved for treatment resistant depression (TRD) and major depressive disorder with suicidal ideation (MDSI). This means that no matter how you feel after ketamine-based treatment at a SPRAVATO® REMS-certified location, you can rest assured that proper protocol will be followed. It also means that treatment is covered by insurance. Ketamine IV therapy, on the other hand, is not.

esketamine nasal spray consultations to help you learn whether you’re a fit for SPRAVATO®. If you’d rather not deal with how you feel after ketamine treatment, we also offer transcranial magnetic stimulation (TMS), a medication-free, FDA-cleared depression treatment. Learn how TMS works

We’ve all heard the common health-related misconceptions or myths-- chocolate causes acne, carrots will improve your night vision, and cracking your knuckles gives you arthritis. Subscribing to these particular myths is relatively harmless, but other health-related misconceptions can have far more serious consequences. This is the case for depression—the myths surrounding it can prevent people from getting the help they need.

Starting any medical treatment for the first time can leave you with questions, especially if you’re looking forward to the benefits it may bring. It’s no different when you’re preparing for your nasal esketamine treatment. Your previous mental health treatments may have consisted solely of taking antidepressants at home or visiting a therapist’s office for cognitive behavioral therapy (CBT), so nasal esketamine is probably a new treatment experience for you. If you're wondering what it's like to start nasal esketamine and get ready for your first session, keep reading. Getting Started with the Nasal Esketamine Treatment As with any new treatment, you’ll first talk to your primary care provider or psychiatrist about whether nasal esketamine is a good fit for you. Alternatively, you can schedule your esketamine nasal spray consultation with a treatment center (such as Greenbrook) that has certification by the FDA’s Risk Evaluation and Mitigation Strategy (REMS). At Greenbrook's REMS-certified nasal esketamine treatment centers, our Greenbrook-affiliated psychiatrists and psychiatric nurse practitioners will review your medical history and also conduct our own assessment to help determine whether nasal esketamine treatment is right for you. Certain conditions, including blood vessel disease and a history of psychosis, may make treatment a risk for you. Make sure you discuss all previous and present conditions with your doctor or nasal esketamine provider before beginning treatment. If the medication is deemed a good fit, you’ll receive your prescription from the Greenbrook-affiliated provider. Your Greenbrook Care Team will put together a personalized care plan for the weeks and months to follow. Keep in mind that you will need to take a standard (oral) antidepressant along with your nasal esketamine treatment. There are two important regulations to note when it comes to preparing for treatment: Each treatment is followed by a mandatory two-hour observation period. This means you will need to plan to stay at the center for at least two hours following your self-administration of the esketamine nasal spray. You cannot drive during the rest of the day after treatment and must arrange for transportation. These regulations are mandatory. It may be helpful to sit down and plan out several weeks’ worth of transportation once you know your treatment schedule. In addition, if you’re wondering what to bring for the treatment, we recommend entertainment such as an audiobook or playlist of favorite songs and a pair of headphones. You may want them during the two-hour observation period. What to Expect During Nasal Esketamine Treatment On the day of treatment, you’ll need to stop eating any food two hours before your appointment and stop drinking all fluids 30 minutes before you come in. Your Greenbrook Care Team will confirm that you are prepared for the two-hour observation period and that you have a ride home. You’ll get the opportunity to practice using a “trainer sprayer” that mimics the real nasal esketamine sprayer but does not release any medication. The Care Team will encourage you to use the restroom and set up your preferred environment in your private treatment bay or room. Some patients like reduced lighting, for example, while others don’t request light adjustments. You’ll complete a depression scale before each treatment session. Your Greenbrook provider will confirm that the dose kit is yours, show you how to administer it, and then hand it to you. Each sprayer contained 28mg of Spravato esketamine nasal spray. Patients usually start with two sprayers (56mg) and soon increase to 84mg (three sprayers) per treatment. But, your dosage maybe vary. Should you be left with a metallic taste by the spray, the Care Team will offer suckers to help make the flavor dissipate. After your dose, you’ll be encouraged to lie back in your comfortable recliner. While most patients enjoy a quiet setting, Greenbrook is prepared to accommodate patients with a more animated reaction to the medication. You may feel sleepy, dizzy, mildly dissociated, and/or nauseated during treatment. Greenbrook's Care Team is readily available if you need assistance. How to Prepare for after your Nasal Esketamine Treatment  Most side effects begin to wane in the second hour of observation, but if you’re wondering, “Is it safe to drive immediately after nasal esketamine treatment?” the answer is a resounding no. In addition to the mandatory ride home, you will need to block off time to rest and let side effects fully dissipate. This extended rest period is especially important in the first weeks of treatment when you’ll have treatment twice a week. Do not drive or operate machinery of any kind until the day after treatment. Just take it easy, relax, and take care of yourself. If you’re unsure what activities you can do or should avoid during this time, talk to your Care Team for more information. While side effects tend to dissipate completely after a good night’s sleep, many nasal esketamine patients begin feeling relief from depression symptoms within hours of their treatment. Other Tips in Preparing for Your Nasal Esketamine Treatment At Greenbrook, we make every effort to schedule your treatment in the afternoons or whenever it is most convenient for you. We encourage you to see each treatment session as an opportunity to relax and take care of your mental health. If you have any questions or concerns, talk to your doctor or the Greenbrook Care Team.
