Drug testing for benzodiazepines

Benzodiazepines are Schedule III drugs and are a type of medication known as tranquilizers, as they act as central nervous system depressants. They are some of the most commonly prescribed medications in the United States, most often used for the treatment of anxiety and insomnia. Physical side effects can include sedation, slurred speech, motor incoordination, disorientation and drunk-like behavior (in the absence of alcohol). Dangers of benzodiazepine use include shallow respiration, cold and clammy skin, dilated pupils, weak and rapid pulse, coma and possible death, especially when taken in combination with alcohol. 
Common benzodiazepines and/or specific metabolites include Oxazepam (Serax®), Nordiazepam, Temazepam (Restoril®), Flurazepam (Dalmane®), Alprazolam (Xanax®), Lorazepam (Ativan®), Chlordiazepoxide (Librium®), Clorazepate (Tranxene®), Diazepam (Valium®), Halazepam (Paxipam®), Medazepam (Nobrium®), Prazepam (Centrax®), Flunitrazepam, Clonazepam (Klonopin®) and Midazolam (Versed®).
Employers can screen applicants and employees to deter drug use and keep their workplaces drug-free.
