Tizanidine, a muscle relaxant, is primarily used to manage spasticity. Standard drug screenings typically do not include tests specifically designed to detect its presence. Consequently, a routine drug test panel is unlikely to reveal its usage.
The absence of tizanidine from common drug test panels stems from several factors. These include the relatively low potential for abuse compared to other controlled substances, as well as the cost and complexity associated with developing and implementing specific assays. Historically, drug testing has focused on substances with higher rates of misuse and dependence.
