What is Spravato’s form?

Spravato comes as a liquid solution in a nasal spray device. You take it by spraying it into your nose.

What strength does Spravato come in?

Spravato comes in one strength of 28 milligrams (mg).

Spravato is available in a 56-mg dose pack that includes two 28-mg nasal sprays. It’s also available in an 84-mg dose pack that includes three 28-mg nasal sprays.

What are the usual dosages of Spravato?

The information below describes the strength and dosing frequency most commonly prescribed or recommended. Your doctor will determine the best dosage to fit your needs.

Each nasal spray device has 28 mg of Spravato and contains two sprays. You will use more than one device to get your full dose. For example, you’d use two devices (four sprays) to get a 56-mg dose of the drug.

Dosing schedule for treatment-resistant depression

Treatment-resistant depression (TRD) is depression that doesn’t improve even after you’ve tried at least two different antidepressants. If you take Spravato for this condition, your dosing schedule will have an induction phase and a maintenance phase.

When you start Spravato, you’ll follow a schedule called the induction phase. This dosing schedule lasts 4 weeks. It helps your doctor safely figure out what the best dose is for you.

After the induction phase, you and your doctor will decide whether to continue Spravato treatment. It depends on how well Spravato has helped your TRD and how well you tolerate the medication.

If you continue treatment, you’ll follow a schedule called the maintenance phase. In this phase, you’ll take doses less often than in the induction phase. Your doctor will prescribe the maintenance dosage of Spravato that’s best for you.

Typical dosages for induction (starting) phases and maintenance (ongoing) phases are shown below.

Weeks 1*–456 mg or 84 mgtwice per week
Weeks 5–856 mg or 84 mgonce per week
Weeks 9 and on56 mg or 84 mgonce every 1 or 2 weeks

* The first dose of Week 1 is 56 mg.

You’ll usually take Spravato along with another antidepressant, which typically comes in the form of a pill that you swallow.

Dosing schedule for major depressive disorder with suicidal thoughts and behavior

Major depressive disorder is sometimes referred to as depression. One kind of depression includes a sudden onset of suicidal thoughts or behaviors.

The usual dosage of Spravato for this condition is 84 mg twice per week for 4 weeks.

If you have any bothersome side effects, your doctor may lower your dosage to 56 mg twice per week.

Spravato is not usually prescribed as a long-term treatment for this condition. Your doctor will determine whether you will keep taking Spravato after 4 weeks.

You’ll usually take Spravato along with another antidepressant, which typically comes in the form of a pill you swallow.

Is Spravato prescribed long term?

You may or may not take Spravato long term. This will depend on the condition you are taking Spravato to treat and how your body responds to the drug. Talk with your doctor about whether Spravato is a good long-term treatment option for you.

Dosage adjustments

Spravato dosing is not adjusted based on liver or kidney problems. But if you have liver problems, your doctor might monitor you for a longer period of time after each dose of Spravato.

Doctors usually adjust Spravato based on how well it works and whether it causes side effects.

Below are answers to a few commonly asked questions about Spravato.

Is the dosing schedule for esketamine the same as for Spravato?

Yes, there is only one dosing schedule right now. Esketamine is the name of the active ingredient in Spravato. There isn’t a generic version of esketamine, so the only dosing schedule is for the brand-name drug, Spravato.

What is the Spravato REMS program?

The risk evaluation and mitigation strategy (REMS) program is a safety program run by the Food and Drug Administration (FDA). You and your doctor will have to agree to follow certain rules in order for you to safely take Spravato.

The following are examples of rules in the REMS program:

  • You’ll stay at the healthcare facility for at least 2 hours after your dose.
  • You’ll have someone give you a ride home.
  • You won’t drive or do other tasks that require an alert mind on the day of your dose.

Learn more about the Spravato REMS program on the program’s website or call 855-382-6022. And talk with your doctor if you have questions about the REMS requirements.

Is Spravato the same thing as ketamine?

No, Spravato is not the same drug as ketamine. The active ingredient in Spravato is esketamine. There is some esketamine found in ketamine, but they are two separate drugs prescribed for different purposes. For example, ketamine is prescribed as an anesthetic for surgery, and esketamine is not.

You’ll take Spravato by spraying it into your nose. This drug is always taken in a medical facility under the direct guidance of a doctor. They’ll provide step-by-step instructions and make sure you give yourself the dose correctly. And they’ll continue to watch you for any side effects for at least 2 hours afterward.

People who take Spravato sometimes get nauseous, so you may be advised to avoid eating for 2 hours before your dose. You may also be advised to avoid drinking any fluids for 30 minutes beforehand.

Your doctor will give you the correct number of nasal (nose) spray devices to get your full dose. For example, you’ll use three devices to get a dose of 84 milligrams (mg).

Before taking your dose, you’ll blow your nose. Then, you’ll lean your head back slightly, put the tip of the nasal spray device into one nostril, and press your other nostril closed. You’ll breathe in through your nose as you press the plunger completely up. Then you’ll breathe in again through your nose gently. The second spray will use the same device in your other nostril. You’ll then wait 5 minutes before using the next device if your dose requires it.

The dosage of Spravato you’re prescribed may depend on several factors. These include:

  • the kind and severity of the condition you’re taking Spravato to treat
  • your age
  • other medications you take
  • your body’s response to the drug, such as side effects including:

Spravato is a Schedule III controlled substance with a boxed warning regarding the risk of misuse (also known as abuse). A boxed warning is the most serious warning from the Food and Drug Administration (FDA). With misuse, a drug is taken in a way other than how it’s prescribed. This can lead to dependence. (For more on dependence, see the section directly below.)

The risk of misuse with Spravato is lowered because it is given in a healthcare facility. You’ll only take Spravato under the supervision of a healthcare professional.

For more information about the potential for misuse with Spravato, see the “Boxed warning” section in the introduction of this article.

Spravato is a controlled substance. That means it’s a drug the government regulates due to the risk of misuse and dependence. With dependence, your body needs the drug to feel like it usually does. (For more information on misuse, see the section directly above.)

No withdrawal symptoms were seen up to 4 weeks after Spravato treatment was stopped in studies. Withdrawal symptoms are side effects that can occur when you stop taking a drug that your body has become dependent on.

It isn’t known whether withdrawal symptoms might occur if Spravato is stopped after being taken for a longer time or in higher dosages than what was studied.

A similar drug, ketamine, is known to cause symptoms of withdrawal, such as:

But these symptoms have not been seen in people taking esketamine (the active drug in Spravato).

Talk with your doctor about the possible risk of dependence and withdrawal with Spravato.

The sections above describe the usual dosages provided by the drug’s manufacturer. If your doctor recommends Spravato for you, they’ll prescribe the dosage that’s right for you.

  • Will my dose of Spravato be different if I also take other antidepressants?
  • Will I need to reschedule my Spravato dose if I have a stuffy or runny nose that day?
