What Is Ketamine?

Ketamine is an anesthetic first developed in the 1960s. At first, doctors used it during surgery to help with pain and sleep. Today, it has a new use. In small doses, ketamine can help ease depression, PTSD, anxiety, chronic pain, and more. It works fast by changing how the brain uses a chemical called glutamate. This chemical helps with mood, memory, and how we learn.For mental health, ketamine is given in low doses in a few ways. These include IV (into the vein), IM (into the muscle), or as a small tablet that melts in the mouth. IV ketamine and IM ketamine are the most commonly used in clinics. During each session, staff watch closely to make sure everything goes well.In many cases, ketamine is tried after standard antidepressants fail. Still, many people feel better after just a few visits. In fact, a study from the National Library of Medicine found that a single IV dose of ketamine led to fast relief in people with hard-to-treat depression. About 64% of patients felt better within 24 hours, compared to 28% who received a different treatment.

Ketamine Benefits

Ketamine therapy has helped many people when other treatments didn’t work, offering benefits such as:

  • Fast relief: Many people feel better within hours or a few days, while most antidepressants take weeks to start working.

  • Brain support: Ketamine helps the brain form new pathways, which may lead to clearer thinking and fewer low moods over time.

  • Flexible treatment options: Ketamine is administered through a vein (IV) or muscle (IM), with doses adjusted based on how the person feels.

  • Short visits: Most sessions last 40 to 60 minutes and take place in a clinic with trained staff nearby.

  • Fewer side effects: Some people experience mild side effects, like dizziness or nausea, but these usually go away quickly.

  • Works when others fail: For many, ketamine provides relief after other drugs have not worked.

What Is Esketamine (Spravato)?

Esketamine is a newer version of ketamine, sold under the name Spravato and approved by the FDA in 2019. Unlike regular ketamine, it uses only one part of the drug, the “S” form, which may work better for some people. Spravato is administered as a nasal spray, but it must be used in a clinic under medical supervision. After each dose, patients remain for at least two hours so staff can monitor for side effects. Often, doctors combine esketamine with an oral antidepressant for better results.

 

Spravato is made by a drug company, comes with strict rules, and is only given through approved clinics with a set dose plan. It is only administered through approved clinics with a set dosage plan. This makes it different from generic ketamine, which offers more flexibility. In many cases, doctors use esketamine when other treatments fail or when a person has strong thoughts of self-harm. While it works similarly to ketamine, the form and setting are different.

 

According to a study in the American Journal of Psychiatry, adults with hard-to-treat depression felt more relief when they took esketamine nasal spray along with a new antidepressant. They improved more than those who took a fake (placebo) spray. The study lasted four weeks and included 197 people. It showed that esketamine helped lower depression scores faster and more effectively for many patients.

Esketamine Benefits

Esketamine offers key benefits for people who qualify for this treatment:

  • FDA approved: Esketamine has passed strict testing, which gives people more trust in its safety and use.

  • Easy to use: It is a nasal spray, not a shot or IV, making it a good choice for people who do not like needles.

  • Clinic care: A clinic administers each dose, and staff monitor the person during and after the treatment to ensure safety.

  • May cost less: Since it is FDA-approved, many health plans help cover the cost, making it cheaper than regular ketamine.

  • Fewer side effects: Some people report feeling less dizzy or spaced out with esketamine compared to ketamine. However, this can vary from person to person.

Esketamine vs Ketamine: Key Differences

When comparing ketamine vs. esketamine, a few important differences stand out:

  • Chemical makeup: Ketamine has two parts, the “R” and “S” forms. Esketamine uses only the “S” form, which may act more strongly in the brain.

  • How it’s given: Ketamine is delivered by IV or a shot into the muscle, while esketamine is administered as a nasal spray.

  • FDA status: Only esketamine is FDA-approved for depression, making it more likely to be covered by insurance. Ketamine is used “off-label” and is often paid for out of pocket.

  • Clinic requirements: Esketamine must be given in a certified clinic with at least two hours of monitoring, while ketamine clinics may have more flexible rules.

  • Patient response: Some people respond better to one treatment than the other.

Choosing Between Ketamine and Esketamine

When choosing between ketamine vs esketamine, several personal and health factors come into play. One of the biggest is cost. If insurance coverage matters most, esketamine may be the better choice since it is FDA-approved and more likely to be covered. On the other hand, ketamine is often not covered, which can raise out-of-pocket costs.

 

Next, consider the type of care that feels best. Some people prefer the nasal spray because it avoids needles, while others may like the control and steady dose that IV ketamine provides. Additionally, session time and clinic rules can vary, which may affect comfort and routine.

 

Consider what treatments have been tried before, as both ketamine and esketamine may offer hope if oral antidepressants haven’t worked.  A provider can help weigh the pros and cons of ketamine vs. esketamine based on past treatments, health needs, and goals. With the right plan, people often feel more at ease and more in control of their mental health journey.
