Dexrazopiclone is best taken when the patient goes to bed. Because dexrazopiclone has a very rapid onset of action, dexrazopiclone should be taken as close to bedtime as possible, or when the patient is already in bed but has difficulty sleeping. Patients taking dezopiclone on day 2 will not experience a hangover-like reaction that occurs with other sleeping pills and is relatively safe. For example, the commonly used drugs such as diazepam, eszopiclone and alprazolam tend to have a hangover on the 2nd day, and the patient will show a feeling of light-headedness. Dexrazopiclone is not, so it is safer for the elderly to take dexrazopiclone. Dexzopiclone should be taken before going to bed, it should be noted that Dexzopiclone is after all also a sedative and sleeping drug, the principle of application is also a small dose of as-needed medication, avoiding a long time to take the drug.
