Narcolepsy is a chronic sleep disorder that affects approximately 1 in 2,000 people in the United States. It is characterized by excessive daytime sleepiness, sudden loss of muscle tone (cataplexy), hallucinations, and sleep paralysis. Xywav is a medication that has been approved by the FDA for the treatment of narcolepsy. Here are 10 things you need to know about Xywav:
- What is Xywav?
Xywav is a prescription medication that contains a mixture of sodium oxybate and calcium, magnesium, potassium, and sodium cations. It is taken orally and works by decreasing the number of cataplexy attacks and improving daytime sleepiness in patients with narcolepsy. - How does Xywav work?
Xywav works by increasing the levels of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter that helps to regulate sleep and wake cycles. By increasing GABA levels, Xywav helps to promote deep and restful sleep in patients with narcolepsy. - Who can take Xywav?
Xywav is approved for use in adults with narcolepsy. It is not recommended for use in children or adolescents under the age of 18. Xywav should not be taken by pregnant or breastfeeding women, as it may harm the developing fetus or nursing baby. - What are the side effects of Xywav?
Like all medications, Xywav can cause side effects. The most common side effects of Xywav include headache, nausea, dizziness, and difficulty sleeping. In some cases, Xywav may also cause more serious side effects, such as depression, anxiety, or suicidal thoughts. If you experience any of these side effects while taking Xywav, you should contact your healthcare provider immediately. - How is Xywav taken?
Xywav is taken orally, usually in two divided doses. The first dose is taken at bedtime, while the second dose is taken 2.5 to 4 hours later.

It is important to follow your healthcare provider's instructions carefully when taking Xywav. - How long does it take for Xywav to work?
Some patients may experience an improvement in their symptoms within a few days of starting Xywav, while others may not see any improvement for several weeks.

If you have any questions or concerns about your treatment with Xywav, you should talk to your healthcare provider. - Can Xywav be taken with other medications?
