Q: What is Xyrem used for?

Xyrem is used to treat cataplexy in narcolepsy and excessive daytime sleepiness in narcolepsy.

Q: How does Xyrem work?

Mechanism of Action The exact mechanism by which Xyrem works to treat narcolepsy is not fully known. It is a central nervous system depressant that is thought to act on certain neurotransmitters in the brain, specifically gamma-aminobutyric acid (GABA). It is believed that its effects are mediated through GABA-B receptors during sleep. Impact on Sleep Architecture Xyrem helps regulate the sleep-wake cycle by changing how the brain moves through different stages of sleep. Its primary functions include: Increasing Slow-Wave Sleep: It promotes deeper, more restorative stages of sleep that are often fragmented in people with narcolepsy. Reducing Nighttime Disruptions: By consolidating sleep, it helps prevent frequent awakenings throughout the night. Managing Daytime Symptoms: By improving the quality of rest at night, the medication helps reduce excessive daytime sleepiness and the occurrence of cataplexy (sudden loss of muscle strength). Because the medication significantly slows brain activity, it is typically taken in two doses: one at bedtime and another several hours later to maintain its effect throughout the night.

Q: What are the active ingredients in Xyrem?

The active ingredient in Xyrem is oxybate .

Q: What are the side effects of Xyrem?

Q: Is Xyrem safe during pregnancy and breastfeeding?

Pregnancy There are no adequate and well-controlled studies regarding the use of Xyrem in pregnant women.

It is important to talk with a healthcare provider about the risks and benefits if you are pregnant or planning to become pregnant while taking this medication. Breastfeeding Xyrem is known to pass into breast milk. The impact on a nursing infant and on milk production is not well established. If you are breastfeeding while taking this medication, you should monitor your infant for potential side effects, such as: Increased sleepiness or sedation Trouble breathing Changes in feeding patterns or poor weight gain Decisions regarding breastfeeding while using Xyrem should be made in consultation with a healthcare professional to weigh the benefits of breastfeeding against the potential risks to the infant.

Q: What is the FDA approval status of Xyrem?

FDA Approval and Indications The U.S. Food and Drug Administration (FDA) approved Xyrem (sodium oxybate) to treat cataplexy and excessive daytime sleepiness in patients 7 years of age and older with narcolepsy. Boxed Warning Xyrem carries a boxed warning, the FDA's most serious warning, because it is a central nervous system (CNS) depressant and has the potential for abuse and misuse. The active ingredient in Xyrem is a form of gamma-hydroxybutyrate (GHB). Misuse of GHB is associated with serious safety risks, including seizures, coma, and death. Even at recommended doses, Xyrem can cause severe breathing problems and loss of consciousness. REMS Program Because of these risks, Xyrem is only available through a restricted distribution program called the Xyrem REMS (Risk Evaluation and Mitigation Strategy). This program requires that: Healthcare providers who prescribe the drug must be specially certified. The medication is only dispensed by a designated central pharmacy. Patients and caregivers receive education on the risks and the importance of safe storage to prevent accidental ingestion or misuse. Controlled Substance Status Xyrem is classified as a Schedule III controlled substance for medical use. The FDA has issued safety communications warning that Xyrem should not be used with alcohol or other drugs that cause sleepiness or slow breathing, as this combination can lead to life-threatening respiratory depression.
