Yes, Xywav has the potential to be habit forming. This means that taking the drug long-term could lead to dependence. Drug dependence occurs when your body needs a drug to be present in your system in order to function like usual. Xywav also has a boxed warning for the risk of misuse.* Misuse refers to taking a drug in a way other than how a doctor prescribes it. Because of these risks, Xywav is a controlled substance. This means that doctors and pharmacies must follow certain regulations to prescribe and dispense it.It’s important to take Xywav exactly as your doctor has prescribed it. Do not change your dosage or adjust the way you take Xywav without talking to your doctor. If you have other questions about the risks of taking Xywav, talk with your doctor. They can help you decide whether Xywav is the right treatment option for you.* A boxed warning is the most serious warning from the FDA. To learn more, see the “Xywav precautions” section.
