Your doctor may tell you not to take lemborexant, may need to change the doses of your medications, or monitor you carefully for side effects. Many other medications may also interact with lemborexant, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- tell your doctor what herbal products you are taking, especially St. John’s wort.
- tell your doctor if you have narcolepsy (a condition that causes excessive daytime sleepiness). Your doctor will probably tell you not to take lemborexant.
- tell your doctor if you drink or have ever drunk large amounts of alcohol, use or have ever used street drugs, or have overused prescription medications. Also tell your doctor if you have or have ever had depression; mental illness; thoughts of harming or killing yourself or trying to do so; a problem with heavy snoring; sleep apnea (a condition in which breathing briefly stops many times during the night); other breathing problems or lung diseases such as asthma, bronchitis, and emphysema; cataplexy (episodes of muscle weakness that begin suddenly and last for a short time); or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking lemborexant, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking lemborexant.
- you should know that this medication may cause drowsiness, decreased mental alertness, prolonged reaction time, problems with coordination the day after you take it, blurry or double vision, and may increase the risk that you could fall. Take extra care to be sure you do not fall, especially if you get out of bed in the middle of the night. Your ability to drive or operate machinery the day after you take lemborexant may be impaired even if you feel fully awake. Do not drive a car or operate machinery until you know how lemborexant affects you.
- do not drink alcohol during your treatment with lemborexant. Alcohol can make the side effects of lemborexant worse.
- you should know that lemborexant has caused serious or possibly life-threatening sleep behaviors. Some people who took lemborexant got out of bed and drove their cars, prepared and ate food, had sex, made phone calls, sleep-walked, or were involved in other activities while not fully awake. After they woke up, these people were unable to remember what they had done. These activities may occur with lemborexant whether or not you drink alcohol or also take other sleep medications. Call your doctor right away if you have ever had an unusual sleep behavior while taking lemborexant.
Dosage Of Lemborexant
Lemborexant comes as a tablet to take by mouth. It is usually taken as needed, not more than one time a day, immediately before bedtime. Lemborexant will work faster if it is not taken with a meal or immediately after a meal. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lemborexant exactly as directed.
You will probably become very sleepy soon after you take lemborexant and will remain sleepy for some time after you take the medication. Plan to go to bed right after you take lemborexant and to stay in bed for at least 7 hours. Do not take lemborexant if you will be unable to go to bed right away and remain asleep for at least 7 hours after taking the medication.
You should be sleeping well within 7 to 10 days after you start taking lemborexant. Call your doctor if your sleep problems do not improve during this time, if they get worse at any time during your treatment, or if you notice any changes in your thoughts or behavior.
Lemborexant may be habit forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.
Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with lemborexant and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements.
