The generic name for the drug, Zopisign, is what most people refer to as the Blue Zopiclone Tablets. This sedative-hypnotic medication helps people with insomnia by accelerating their rate of falling asleep and extending their duration of sleep. It is sold under several brands, the most well-known of which is Ambien. Because they have the potential to be abused and cause dependence if not taken as directed, these blue tablets are categorized as a Schedule IV prohibited substance.
