No, Xywav is not a stimulant drug. Instead, it belongs to a class of drugs called central nervous system (CNS) depressants.Similar to Xywav, stimulants can be used to treat idiopathic hypersomnia and narcolepsy. However, Xywav works differently from these drugs. While stimulants help increase alertness while you're awake, Xywav may help calm your brain during sleep. As a result, Xywav isn't a drug that will help you wake up. However, taking this drug may improve sleep and reduce tiredness during the day.If you have other questions about Xywav or stimulants, talk with your doctor or pharmacist.
