Dexrazopiclone tablets are mainly used for the treatment of insomnia, the dose should be individualized, the recommended starting dose for adults is 2mg before going to sleep, as 3mg can prolong the sleep time more effectively, the starting dose can also be adjusted to 3mg according to clinical needs. Dexrazopiclone tablets are fast-acting and can be taken just before bedtime. However, if a high-fat diet or a full meal is taken before bedtime, taking dexrazopiclone tablets may cause slow absorption of the drug, which may result in a longer sleep onset time.
