Question 1

What is Xyrem?

Accepted Answer

Xyrem is a prescription medication that contains the active ingredient sodium oxybate. It functions as a central nervous system depressant by interacting with specific chemical messengers in the brain to help regulate sleep and wakefulness.

This medication is used to address symptoms that impact daytime alertness and nighttime rest. It works by altering brain activity to help stabilize sleep patterns and manage symptoms that occur during the day.

Question 2

What is Xyrem used for?

Accepted Answer

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

Question 3

How does Xyrem work?

Accepted Answer

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.

Question 4

Question 6

What drug class is Xyrem?

Accepted Answer

Question 7

What is the dosage of Xyrem and how do I take it?

Accepted Answer

How to Take Xyrem

Xyrem is a liquid medication taken by mouth. It must be prepared and taken exactly as directed by a healthcare provider. Because this medication causes sleep very quickly, it should only be taken while you are in bed.

Preparation and Timing

Prepare both nightly doses before going to bed. Use the dosing syringe and containers provided with the medication.

Each dose must be mixed with water in the pharmacy-provided containers.

Take the medication on an empty stomach, at least two hours after your last meal.

Take the first dose while sitting in bed and lie down immediately.

Set an alarm to take the second dose between 2.5 and 4 hours after the first dose. You should remain in bed to take the second dose and lie down again immediately afterward.

Missed Dose

If you miss the second dose of the night, skip it entirely. Do not take the medication after you have woken up for the day. Wait until the next night to take your scheduled doses. Never take two doses at once to make up for a missed one.

Question 8

Is Xyrem safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies regarding the use of Xyrem in pregnant women. In animal studies, high doses of the medication were associated with decreased fetal weight and increased risks, though these findings may not directly apply to humans. 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.

Question 9

What forms and strengths does Xyrem come in?

Accepted Answer

Available Forms

Xyrem is available as an oral solution. This liquid medication is clear to slightly opalescent and is intended for oral administration.

The product is supplied in a bottle with a child-resistant cap. It is packaged with a measuring syringe and dosing cups to facilitate the preparation and administration of the liquid.

Question 10

What is the FDA approval status of Xyrem?

Accepted Answer

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.

Question 11

What should I know about Xyrem and addiction?

Accepted Answer

Risk of Misuse and Abuse

Xyrem contains sodium oxybate, which is the sodium salt of gamma-hydroxybutyrate (GHB). GHB is a substance with a known history of abuse and is associated with severe adverse reactions. Because of the risk of misuse, Xyrem is classified as a controlled substance and is only available through a restricted distribution program called a REMS (Risk Evaluation and Mitigation Strategy).

Serious Safety Concerns

Misusing Xyrem or taking it in ways not prescribed can lead to life-threatening complications. These risks are increased if the medication is combined with alcohol or other drugs that cause drowsiness. Serious effects of misuse include:

Severe breathing problems (respiratory depression)

Seizures

Changes in alertness or loss of consciousness

Coma or death

Dependence and Withdrawal

Xyrem can be habit-forming, and patients may develop a physical or psychological dependence on the medication. If the drug is stopped abruptly after long-term use, withdrawal symptoms may occur. These symptoms can include:

Anxiety and agitation

Insomnia

Tremors

Increased heart rate and blood pressure

Hallucinations or confusion

To minimize the risk of addiction and dependence, it is essential to follow the prescribed dosing schedule exactly and never share the medication with others. Healthcare providers will monitor patients for signs of misuse or abuse during treatment.
