Hypnotics are a type of depressant drug that induces sleep and can be fatal if taken in large doses. They come in pill or capsule form and their effects include impaired coordination, internal bleeding, and potentially coma or death from overdose. While sometimes used in hospitals, hypnotics like barbiturates and benzodiazepines are sedative-hypnotic drugs that cause central nervous system depression and have resulted in deaths from misuse and overdoses according to data from poison control centers.
