Dayvigo (lemborexant) is a prescription oral tablet used to treat insomnia in adults. This drug can interact with alcohol, other medications, and some supplements. For example, Dayvigo can interact with alprazolam (Xanax) and zolpidem (Ambien).
An interaction can occur because one substance causes another substance to have a different effect than expected. Interactions can also occur if you have certain health conditions.
Before you start taking Dayvigo, tell your doctor and pharmacist about any prescription, over-the-counter, or other drugs you take. Sharing this information with them may help prevent possible interactions.

Certain health conditions or other factors could raise your risk of harm if you take Dayvigo. In such cases, your doctor may not prescribe Dayvigo for you. These are known as contraindications. Dayvigo has one contraindication, which is described below.
If you have narcolepsy: With narcolepsy, you experience atypical sleep, daytime sleepiness, and “sleep attacks” (overwhelming urges to fall asleep, sometimes suddenly). Dayvigo is prescribed to treat insomnia, which is a condition that causes difficulty sleeping. You should not take Dayvigo if you have narcolepsy, as it may worsen your condition and its symptoms. If you have questions, talk with your doctor.
You should not drink alcohol during your Dayvigo treatment. Doing so can increase the level of Dayvigo in your system. This can raise your risk of side effects, such as problems with balance.
Consuming alcohol can also raise your risk of feeling effects from Dayvigo during the day, such as drowsiness and difficulty concentrating. It can even affect your ability to safely drive, operate machinery, or engage in other activities that require concentration.
If you have questions about avoiding alcohol while taking Dayvigo, talk with your doctor or pharmacist.
Learn more about certain drug interactions that can occur with Dayvigo.
Interaction with benzodiazepines
Dayvigo can interact with benzodiazepines, which are used to treat anxiety, short-term sleep problems, and other conditions.
Examples of benzodiazepine medications include:
- alprazolam (Xanax)
- clonazepam (Klonopin)
- diazepam (Valium, others)
- temazepam (Restoril)
What could happen
Dayvigo and benzodiazepines can both cause central nervous system (CNS) depression. Taking these drugs together can raise your risk of this side effect.
What you can do
If you use Dayvigo with a benzodiazepine, your doctor may prescribe a lower dose of Dayvigo and the benzodiazepine for you. You should not take a higher dose of either medication than your doctor prescribes. Your doctor may also suggest stopping treatment with the benzodiazepine if you’re taking it to treat insomnia, as Dayvigo is prescribed to treat this condition.
If you take Dayvigo and a benzodiazepine together, tell your doctor right away if you have symptoms of CNS depression. These may include slurred speech, drowsiness, and difficulty with coordination and making decisions.
If you have questions about taking Dayvigo with a benzodiazepine, talk with your doctor or pharmacist.
Interaction with other drugs that treat insomnia
Dayvigo can interact with other drugs used to treat insomnia. Examples include:
- eszopiclone (Lunesta)
- zolpidem (Ambien)
- suvorexant (Belsomra)
- ramelteon (Rozerem)
What could happen
Dayvigo is prescribed to treat insomnia. Other drugs used to treat insomnia and Dayvigo can cause some similar side effects, including CNS depression. Symptoms of CNS depression include drowsiness, slurred speech, and difficulty with coordination and making decisions. Taking Dayvigo with another drug that treats insomnia raises your risk of these effects.
What you can do
Your doctor will likely avoid prescribing Dayvigo with another insomnia drug. This combination raises the risk of side effects, and it isn’t likely to be more effective for your insomnia. This is particularly true for “Z-drugs” such as zolpidem and eszopiclone,
Talk with your doctor or pharmacist if you have other questions about this interaction.

Certain medical conditions or other health factors may raise the risk of interactions with Dayvigo. Before taking Dayvigo, talk with your doctor about your health history. They’ll determine whether Dayvigo is right for you.
Health conditions or other factors that might interact with Dayvigo include:
Breathing condition, such as chronic obstructive pulmonary disease (COPD): If you have a breathing condition such as COPD or sleep apnea, Dayvigo could worsen symptoms of it. Your doctor can help determine whether Dayvigo is safe for you to take.
Liver condition: Having a liver condition such as cirrhosis can cause the level of Dayvigo in your system to build up. This can raise your risk for side effects from the drug.

Narcolepsy: You should not take Dayvigo if you have narcolepsy or any other condition that may cause you to suddenly fall asleep during the day. Dayvigo is prescribed to treat insomnia, so it may worsen your condition and its symptoms. If you have questions, talk with your doctor.

If you’ve had a substance use disorder before, such as opioid use disorder, talk with your doctor. They can determine whether it’s safe for you to take Dayvigo.

Before you start taking Dayvigo, talk with your doctor about any mental health conditions you may have experienced.
