HETLIOZ® is a melatonin receptor agonist that is FDA approved for both Non-24-Hour Sleep-Wake Disorder (a serious, chronic circadian rhythm disorder) and nighttime sleep disturbances in Smith-Magenis Syndrome (SMS) in patients 16 years of age and older. In addition, HETLIOZ LQ™ oral suspension is approved for treatment of nighttime sleep disturbances in SMS in pediatric patients 3 years to 15 years of age.
There’s an FDA-approved therapy to help you improve nighttime sleep and decrease daytime sleepiness. Ask your doctor about the first and only treatment for people with Non-24 and nighttime sleep disturbances in SMS, called HETLIOZ® (tasimelteon).
In clinical studies, HETLIOZ® helped many people living with Non-24 and nighttime sleep disturbances in SMS sleep at night and stay awake during the day. Taken as directed by your doctor, HETLIOZ® may help you break the cycle of disrupted nighttime and unwanted daytime sleep that you've been struggling with.
The most common side effects associated with HETLIOZ® include headache, elevated liver enzymes (ALT), nightmares or abnormal dreams, and upper respiratory or urinary tract infection. These side effects may occur more frequently in patients 65 years of age or older.
HETLIOZSolutions™ was created to support people who have been diagnosed with Non-24 or nighttime sleep disturbances in SMS. The program can assist with coordinating care to help answer insurance questions, as well as provide financial support and educational resources. And most importantly, by letting you know that you are not alone on this journey.
If you have questions, help is available by calling HETLIOZSolutions™ at 1-844-HETLIOZ—that's 1-844-438-5469—from 9:00AM to 8:00PM, Monday through Friday, Eastern Standard Time.

Because HETLIOZ® is not available at retail pharmacies, there is a special process that you and your doctor will need to follow to have HETLIOZ® delivered to you. Once you have been diagnosed, and your doctor has determined that HETLIOZ® is right for you, you and your healthcare professional will need to fill out and sign the HETLIOZSolutions™ Prescription and Service Request Form.

The HETLIOZ® Guide for Your Doctor has been written specifically for doctors. The Non-24 Guide covers the science behind a circadian rhythm disorder and the SMS Guide covers the science behind a developmental disorder, both of which result in nighttime sleep disturbances. The safety and effectiveness of HETLIOZ® has been detailed in these resources as well. Be sure to share the information with your doctor if he or she isn't familiar with Non-24, nighttime sleep disturbances in SMS or HETLIOZ®.
If your doctor still has questions about Non-24, nighttime sleep disturbances in SMS or HETLIOZ®, it may be helpful to refer him or her to HETLIOZPRO.com, where we explain Non-24 and how HETLIOZ® can help.
