Restoril is typically taken orally, and its effects can be felt within 30 minutes to an hour of taking it. It has a longer half-life compared to Halcion, ranging from 8-20 hours. This longer duration of action makes Restoril more effective for maintaining sleep throughout the night. However, it also increases the risk of residual sedation and impaired cognitive function the next day. Like other benzodiazepines, Restoril carries the potential for dependence and withdrawal symptoms with prolonged or excessive use.
