In Latin America and Europe, Rohypnol (Flunitrazepam) is prescribed as a short-term treatment for insomnia, and as preanesthetic medication. Flunitrazepam is considered a drug of abuse when used to enhance the effect of other substances such as marijuana, heroin, and ethanol. The combination of ethanol and flunitrazepam may lead to sedation, loss of motor function, impaired judgment, behavioral changes, and anterograde amnesia.

Notes
Reference range is equivalent to lower limit of detection for this assay. Flunitrazepam is typically ingested in small doses and is rapidly metabolized; hence it has a relatively short half-life in serum. Flunitrazepam metabolites may be detected in urine 5 days or more post ingestion, however as small doses are typically ingested, detection in urine is typically limited to the first 24-72 hours. This panel includes Flunitrazepam, 7-Aminoflunitrazepam, and N-Desmethylflunitrazepam.
