Side effect details

Here’s some detail on certain side effects this drug may cause.

Excessive sleepiness and decreased alertness

Belsomra treatment may cause people to feel more sleepy or less alert than usual the next day. Because of this, you should not drive for at least 8 hours after you take a dose of the drug. Belsomra may also affect your ability perform other activities that require full alertness.

In clinical studies of Belsomra, next-day sleepiness was the most common side effect.

Belsomra is a type of drug called a central nervous system (CNS) depressant. It slows down the activity of your brain and nervous system. So Belsomra may reduce your ability to think and react quickly. Even if you don’t feel sleepy the next day, driving or operating heavy machinery may still be dangerous. These effects can last up to several days after your last dose of Belsomra.

20-mg strength and next-day activities

Belsomra oral tablets come in four strengths: 5 milligrams (mg), 10 mg, 15 mg, and 20 mg. It’s possible to have excessive sleepiness and decreased alertness with any dose of Belsomra. But taking a high dose (20 mg) can increase your risk of developing these side effects.

If you’re prescribed a 20-mg dose of Belsomra, your doctor may warn you not to drive at all the next day until you know how the drug will affect you. They may also advise you not to perform next-day activities that require full alertness and clear thinking, until you know how Belsomra will affect you.

Other risk factors

Other factors that can increase the risk of excessive sleepiness and decreased alertness with Belsomra include:

  • taking Belsomra when you have less than 7 hours to devote to sleep before you need to wake up
  • taking Belsomra in combination with other CNS depressants*
  • being age 65 years or older, which could make falls and serious injuries more likely

Keep in mind that not getting enough sleep may make you feel excessively sleepy the next day. Insomnia itself, which Belsomra treats, can reduce your mental alertness.

If you’re concerned about excessive sleepiness or decreased alertness with Belsomra, talk with your doctor.

* For more information, see the “Belsomra interactions” section below.

Unusual sleep behaviors

Taking Belsomra may cause some people to perform unusual behaviors during sleep. These may include getting out of bed and performing activities that you may not remember the next day.

Some reported activities include:

  • sleepwalking
  • making phone calls
  • having sex
  • preparing and eating food
  • driving a vehicle

Some of these behaviors could become dangerous and lead to injuries or, in certain cases, fatal accidents. To other people, it may look like you’re awake while you perform these activities, but your brain isn’t fully alert.

Unusual sleep behaviors may occur after your first dose or at any time during treatment with Belsomra. It isn’t clear how common it is to develop these behaviors with Belsomra.

Using other CNS depressants (including alcohol) in combination with Belsomra can increase your risk for unusual sleep behaviors.

If you or other people in your household inform you that you have unusual sleep behaviors while taking Belsomra, talk with your doctor right away. Your doctor will likely have you stop taking Belsomra. They may also recommend other treatment options for your insomnia.

Other problems related to sleep

In addition to the sleep problems mentioned above, Belsomra may cause the development of other sleep problems. Some of these problems reported in clinical studies include sleep paralysis and hallucinations.

With sleep paralysis, you can’t move or talk for several minutes as you fall asleep or wake up. This occurs when part of your brain fully wakes up, but your muscles are still in sleep mode. This is called rapid eye movement (REM) sleep, during which your muscles are unable to move for a time. This is your body’s way of keeping you from physically moving or flailing around as you dream, which may help prevent injuries. Taking Belsomra may increase the risk of becoming conscious during REM sleep and causing temporary sleep paralysis.

Hallucinations may occur while taking Belsomra. They can include seeing, hearing, or sensing things that aren’t there. These hallucinations occur just as you fall asleep or wake up. They may occur at the same time as sleep paralysis. Some people describe these hallucinations as vivid or disturbing.

It isn’t clear how often these sleep problems happen while taking Belsomra. Experiencing sleep paralysis or hallucinations can be frightening. It’s possible for these side effects to cause intense fear or panic attack symptoms such as chest tightness or tachycardia (increased heart rate).

If you develop sleep paralysis or hallucinations while taking Belsomra, talk with your doctor. They may recommend changes to your treatment plan.

Allergic reaction

As with most drugs, some people can have an allergic reaction after taking Belsomra. Allergic reactions weren’t reported during clinical studies of the drug.

Symptoms of a mild allergic reaction can include:

A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include:

  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your tongue, mouth, or throat
  • trouble breathing

Call your doctor right away if you have an allergic reaction to Belsomra, as the reaction could become severe. Call 911 or your local emergency number if your symptoms feel life threatening or if you think you’re having a medical emergency.

The Belsomra dosage your doctor prescribes will depend on several factors. These include:

  • the severity of the condition you’re taking Belsomra to treat
  • your age
  • other medical conditions you may have
  • other medications you may take

Typically, your doctor will start you on a low dosage. Then they’ll adjust it over time to reach the amount that’s right for you. Your doctor will ultimately prescribe the lowest dosage that provides the desired effect.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Drug forms and strengths

Belsomra comes as oral tablets. They’re available in four strengths: 5 milligrams (mg), 10 mg, 15 mg, and 20 mg.

Dosage for insomnia

The recommended dose of Belsomra for insomnia is 10 mg once per night. You should take your dose within 30 minutes of going to bed and have at least 7 hours before you plan to wake up.

Your doctor will likely tell you that you don’t have to take Belsomra every night. It’s often recommended that you take the medication only as needed.

If your insomnia doesn’t improve, talk with your doctor. They may recommend increasing your dose.

It’s important to take the dose of Belsomra that your doctor prescribes. You shouldn’t take more than one dose of Belsomra per night. The maximum dose of Belsomra is 20 mg.

A lower dosage of Belsomra is recommended for people who may be more sensitive to the drug’s side effects. This includes people taking certain medications* and people ages 65 years and older. Belsomra’s usual maximum dosage in older people is 15 mg per night. This was the maximum dosage studied in older people in Belsomra’s clinical trials.

* For more information, see the “Belsomra interactions” section below.

What if I miss a dose?

If you miss a dose of Belsomra, you should take the missed dose only if you have at least 7 hours before you plan to wake up.

Taking your dose when you have less than 7 hours to devote to sleep increases your risk of side effects. These include next-day sleepiness and reduced alertness,* which can be dangerous if you’ll be driving.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone. You can set the reminder to go off when you usually get ready for bed.

* For more information about this side effect, see the “Belsomra side effects” section above.

Will I need to use this drug long term?

Possibly. Belsomra may be used as a short- or long-term treatment. If your insomnia doesn’t ease within 7 to 10 days of treatment with Belsomra, talk with your doctor. They may check you for other medical conditions that can cause or worsen insomnia.

If you and your doctor determine that Belsomra is safe and effective for you, they may recommend that you continue taking it long term.

Other drugs are available that can treat insomnia (trouble sleeping). Some may be a better fit for you than others. Consider asking your doctor how Belsomra compares with some of its alternatives, such as Belsomra vs. Ambien and Ambien CR, Belsomra vs. Dayvigo, or Belsomra vs. Lunesta.

If you’re interested in finding an alternative to Belsomra, talk with your doctor. They can tell you about other medications that may work well for you.

Keep in mind that some of the drugs listed here are used off-label to treat these specific conditions. Off-label drug use is when an FDA-approved drug is used for a purpose other than what it’s approved for.

Examples of other prescription drugs that may be used to treat insomnia include:

  • lemborexant (Dayvigo)
  • zolpidem (Ambien and Ambien CR)
  • eszopiclone (Lunesta)
  • zaleplon (Sonata)
  • hydroxyzine (Vistaril)
  • ramelteon (Rozerem)
  • tasimelteon (Hetlioz)
  • doxepin (Silenor)
  • trazodone
  • benzodiazepines, such as temazepam (Restoril) or lorazepam (Ativan)

Examples of over-the-counter medications and supplements that may be used to treat insomnia include:

Here are answers to some frequently asked questions about Belsomra.

Is Belsomra addictive? Will it make me feel ‘high’?

Belsomra does not cause physical addiction, but the drug may be psychologically addictive (emotional or mental addiction). And no side effects of euphoria (feeling “high”), physical dependence, or withdrawal were reported in clinical studies.

But Belsomra is classified as a Schedule IV controlled substance because of possible misuse. For more information, see the “Belsomra withdrawal and dependence” section below.

If you have concerns about taking Belsomra, talk with your doctor.

Does Belsomra cause weight loss or weight gain?

Belsomra shouldn’t cause weight loss or weight gain. Weight changes weren’t reported in people who took the drug in clinical studies.

A small, 14-week study looked at the use of suvorexant (the active drug in Belsomra) in people with type 2 diabetes and insomnia. This study showed that Belsomra helped improve sleep quality and reduce waist size. But the results didn’t show significant weight loss.

If you have questions about changes in your weight, talk with your doctor. They may recommend ways to reach or maintain a moderate weight.

Is Belsomra a narcotic?

No, Belsomra isn’t a narcotic.

Belsomra is used to treat insomnia. It belongs to a class of drugs called dual orexin receptor antagonists (DORAs). Narcotics aren’t used to treat insomnia.

Narcotics are opioids, which are used to treat severe pain. Examples of opioids include hydrocodone and morphine.

While Belsomra isn’t a narcotic, it is classified as a controlled substance due to certain risks. (To learn more, see the “Belsomra withdrawal and dependence” section below.)

If you have other questions about Belsomra, talk with your doctor or pharmacist.

Can I take more than 20 mg of Belsomra nightly, such as 30 mg or 40 mg each night?

No, you should not take more than one dose of Belsomra per night. Be sure to take the dosage your doctor prescribes for you.

The maximum recommended dosage of Belsomra is 20 milligrams (mg) per night.

Clinical studies were performed to test the safety of 30-mg and 40-mg doses of Belsomra. The results showed that the higher doses were similar in effectiveness to lower doses. However, the 30-mg and 40-mg doses led to significantly more side effects, such as excessive next-day sleepiness and impaired driving.

If you feel that Belsomra isn’t helping you, you should not take additional doses. Instead, talk with your doctor. They may recommend other treatment options.

Does Belsomra treat anxiety?

No, Belsomra isn’t approved by the Food and Drug Administration (FDA) to treat anxiety. It’s FDA-approved to treat only insomnia in adults.

Since Belsomra was approved, some people taking the drug have reported anxiety. But it isn’t known if the drug was the cause. It’s possible that the anxiety was linked to sleep-related side effects such as sleep paralysis or hallucinations.*

A clinical study looked at suvorexant (the active drug in Belsomra) in hospitalized people with insomnia and mental illness. After 8 weeks of treatment, reports showed that suvorexant helped improve sleep quality and reduce the severity of anxiety. But more research is needed to evaluate the use of suvorexant for anxiety.

If you have questions about anxiety treatments, talk with your doctor.

* For more information, see “Side effect details” in the “Belsomra side effects” section above.

Will Belsomra show up on drug tests?

It’s possible. It depends on which drug test is being performed. Belsomra may stay in your system for several days after your last dose.

If you have other questions or concerns about drug tests, it’s best to talk with your doctor.

The Food and Drug Administration (FDA) approves prescription drugs such as Belsomra to treat certain conditions. Belsomra may also be used off-label for other conditions. Off-label drug use means using a drug for a purpose other than what it’s been approved for by the FDA.

Belsomra is approved by the Food and Drug Administration to treat insomnia (trouble sleeping) in adults.

Belsomra belongs to a class of drugs called dual orexin receptor antagonists (DORAs). A class of drugs is a group of medications that have a similar mechanism of action. A drug’s mechanism of action is the way it works in your body.

Belsomra works by stopping the action of a brain chemical known as orexin. (It’s believed that this chemical has a role in telling your brain to wake up.) By stopping this action, your brain doesn’t get the message to wake up, so you stay asleep.

Belsomra’s half-life

In a healthy person, Belsomra has an average half-life of 12 hours. (A drug’s half-life is the amount of time it takes for the body to eliminate half a dose.) The half-life may be longer in people who are ages 65 years and older, have other medical conditions, or take certain medications.

It takes four to five half-lives for the body to eliminate a drug from your system. So, it may take an average of 2 to 3 days for your last dose of Belsomra to be fully removed from your body.

How long does it take to work?

Belsomra starts working as soon as you take your first dose. This is why you should take your dose within 30 minutes before you go to bed.

If you don’t notice your insomnia easing after taking Belsomra for 7 to 10 nights, talk with your doctor. They can adjust your treatment plan as needed.

You should not drink alcohol with Belsomra. Studies showed that consuming alcohol with Belsomra can impair your ability to think and talk clearly as well as walk and move normally.

Belsomra and alcohol are both central nervous system (CNS) depressants. This means they can slow down your brain’s activity.

Drinking alcohol while taking Belsomra can cause you to think and talk less clearly and move less well than usual. The combination of alcohol and Belsomra may also increase your risk of side effects, such as:

If you choose to drink alcohol while being treated with Belsomra, then you should not take your dose of Belsomra that evening before you go to bed. If you have questions about consuming alcohol while taking this drug, talk with your doctor.

Belsomra can interact with several other medications. Different interactions can cause different effects. For instance, some interactions can interfere with how well a drug works. Other interactions can increase the risk of side effects or make them more severe.

In some cases, your doctor or pharmacist may recommend dosage adjustments so that you may continue taking a necessary medication while you take Belsomra.

Belsomra and other medications

Below is a list of medications that can interact with Belsomra. This list does not contain all drugs that may interact with Belsomra.
