How does this medication work? What will it do for me?

Esketamine belongs to the class of medications called antidepressants. It is used by adults, in addition to either a selective serotonin reuptake inhibitor (SSRI) or a serotonin-norepinephrine reuptake inhibitor (SNRI), to treat moderate-to-severe depression. It intended for people with major depressive disorder who have tried at least two different antidepressants which did not treat their depression adequately.

The exact way esketamine works to treat mood disorders has not been fully determined, although it is believed to work by changing the activity of certain natural chemicals in the brain.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

What form(s) does this medication come in?

Each single-use device contains 0.2 mL of an aqueous solution that delivers 28 mg of esketamine in 2 sprays (one for each nostril). Nonmedicinal ingredients: citric acid monohydrate, sodium edetate, sodium hydroxide, and water for injection.

How should I use this medication?

The recommended adult starting dose of esketamine is 56 mg given intranasally (into the nose) twice a week for 4 weeks. Depending on how you are feeling and how well the medication works, your doctor may adjust the dose. People with Japanese heritage or people over the age of 65 may require lower doses of this medication. Talk to your doctor if this applies to you.

Each spray device delivers 2 sprays (one in each nostril) for a dose of 28 mg of medication. If your dose is more than 28 mg, wait 5 minutes to allow the medication to be absorbed and then repeat this process with a second device.

This medication is usually taken until 6 months after the symptoms of depression have resolved.

Before using the device, gently blow your nose. Do not prime the device before using it. This will cause medication to be discharged from the device and you will not get the full amount of medication for each dose. Tilt your head back approximately 45 degrees and place the tip of the device into one nostril. Hold the other nostril closed and gently inhale through your nose as you activate the spray. Gently sniff, to keep the medication in your nose. Breathe through your mouth. For the second spray, repeat this process with the other nostril.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take this medication exactly as prescribed by your doctor. Esketamine must be given at the doctor’s office or clinic where blood pressure and mental changes can be monitored for at least 2 hours after using the medication. If you miss an appointment to receive esketamine, contact your doctor as soon as possible to reschedule your appointment.

This medication will be stored by your doctor and given to you to use when you arrive for your appointment for treatment.

Your doctor will have you rest at the office or clinic to monitor your feelings of drowsiness or perception until your thinking has returned to normal.
