While it is not known how XYREM works, it is thought that XYREM, taken at night, works to impact certain natural chemicals in the brain (called neurotransmitters) to help relieve the daytime symptoms of cataplexy and EDS in narcolepsy.
Supported by years of clinical research
XYREM has been studied for more than 20 years.
XYREM has been prescribed to adults since 2002
In addition, XYREM was approved by the FDA in 2002 for treating cataplexy in narcolepsy and in 2005 for EDS in narcolepsy in adults. As of 2018, healthcare professionals have prescribed XYREM for more than 64,000 patients.
It is important to know all of this because the active ingredient in XYREM is a form of gamma hydroxybutyrate, or GHB. GHB exists normally in the body and performs important functions, but it also has been improperly manufactured and abused. XYREM, however, is made under strictly controlled conditions and can only be received through a central Certified Pharmacy as part of a restricted distribution program called the XYREM® REMS Program. The XYREM REMS Program was developed with the FDA to help make sure that XYREM is shipped to you securely and that you know how to use it properly.

How to help your child get the most from XYREM treatment
XYREM is a liquid that is taken at night in 2 separate doses. That means if your child is prescribed XYREM, you will need to create a routine to fit XYREM into your family’s nightly schedule. Staying in close contact with your healthcare provider can help you make the most of your child’s treatment. Also, you may have to help your child make certain lifestyle changes regarding meal times or bedtime. Review step-by-step instructions on how to prepare the nightly XYREM doses and give them to your child.
Staying on schedule
If your child has been prescribed XYREM, it’s important that he or she takes XYREM every night exactly as instructed by the healthcare provider. Do your best to make sure that your child does not skip a night or miss the second dose. Using an alarm can help you and your child wake up at the right time to take the second dose. If your child does miss the second dose, skip that dose and do not take XYREM again until the next night. Never take 2 doses at the same time. That can cause serious side effects.
Keeping in touch with your child’s healthcare provider
Checking in with a healthcare provider every 3 months is very important to let him or her know if your child’s symptoms are improving and about any side effects, including nausea, vomiting, or dizziness. This is important so that a healthcare provider can make sure the dosage is correct and help manage any side effects. The healthcare provider may adjust your child’s XYREM dosage to make sure that he or she is getting the appropriate dosage.
Taking XYREM without food
Food can affect how much XYREM is absorbed. So if your child is prescribed XYREM, he or she should wait at least 2 hours after eating before taking the first nightly dose.
- You may need to change your child’s normal dinnertime and cut out late-night snacks.
- Some people find eating dinner at the same time every night helps with their nighttime routine.
Involving family and loved ones
You and your family are special sources of support for your child who has narcolepsy. Share what you learn about XYREM with the rest of the family and loved ones and let them know how your child is doing with treatment. That way they may be there to help you or your child prepare or take XYREM properly and to offer support with any lifestyle changes you decide to make.
Important rules for safety

FREQUENTLY ASKED QUESTIONS
XYREM is a prescription medicine approved by the Food and Drug Administration (FDA) to treat 2 symptoms of narcolepsy: excessive daytime sleepiness (EDS) and cataplexy. XYREM is only available through the XYREM REMS Program.
XYREM is taken at night to reduce both excessive daytime sleepiness (EDS) in narcolepsy and cataplexy in narcolepsy during the day.
XYREM can cause sleep very quickly. Some people fall asleep within 5 minutes, and most people fall asleep within about 15 minutes. That is why your child needs to be in bed for each dose during the night.
Make sure your child takes XYREM exactly as instructed by his or her healthcare provider:
- XYREM is taken in 2 doses nightly.
Give the first dose at bedtime while your child is in bed.
- - If your child sleeps more than 8 hours per night, the first dose may be given at bedtime or after an initial period of sleep.
- The second dose is taken 2½ to 4 hours later while still in bed.
If you or your child wakes up early for the second dose:
- - Do not give the second dose before the scheduled time of 2½ to 4 hours after the first dose. This could cause serious side effects or safety issues. Wait at least 2½ hours before giving the second dose or as your child’s healthcare provider has instructed.
Alcohol, other sleep medicines, or sedative medications SHOULD NOT be taken with XYREM.
If your child experiences the following serious side effects while using XYREM, you should call the healthcare provider immediately:
Breathing problems, including:
- Slower breathing
- Trouble breathing
- Short periods of not breathing while sleeping (sleep apnea). People who already have breathing or lung problems have a higher chance of having breathing problems when they use XYREM.
Mental health problems, including:
- Seeing or hearing things that are not real (hallucinations)
- Unusual or disturbing thoughts (abnormal thinking)
- Feeling anxious or upset
- Thoughts of killing himself or herself or trying to kill himself or herself
Call your doctor right away if your child has symptoms of mental health problems.
- Sleepwalking. Sleepwalking can cause injuries. Call the doctor if your child starts sleepwalking. The doctor should check your child.
In clinical studies, some of the most common side effects seen with XYREM in pediatric patients were:
- Decreased appetite
- Weight decrease
These are not the only possible side effects with XYREM. If you or your child is concerned about any possible side effects with XYREM, talk with your child’s healthcare provider. He or she may have suggestions for managing any side effects your child experiences.
If your child misses the second nightly dose, skip that dose and do not give XYREM again until the next night. Never take 2 doses at the same time. This could cause serious side effects or safety issues.
In addition, if your child does not take the second dose within 24 hours of mixing it with water, you should throw it away.
Taking the 2 separate doses is important to get the desired effect. Never give both XYREM doses at the same time. This could cause additional side effects or safety issues.
While it is not known how XYREM works, it is thought that XYREM, taken at night, works to impact natural chemicals in the brain (called neurotransmitters) to help relieve the daytime symptoms of cataplexy and EDS in narcolepsy.
XYREM can cause sleep very quickly and also leaves your child’s system quickly. Setting an alarm should help you and your child wake up when you need to.
