If you’re taking tizanidine for muscle spasms, you might wonder if it’ll show up on a drug test. This is a big concern for people who need to pass regular tests for work, sports, or medical reasons. Some people worry that tizanidine could cause false positives or be mistaken for other drugs.
But there are some facts we should know to put our minds at ease.
Tizanidine, a muscle relaxant, is not typically included in standard drug screening panels. However, there are instances where it may cause false positives or interfere with the accuracy of drug tests.
Scientific research and expert opinions suggest that tizanidine is unlikely to be detected in routine drug tests, such as those conducted by the Department of Transportation (DOT), which focus on substances like marijuana, cocaine, opiates, amphetamines, and phencyclidine (PCP). However, if an employer opts for a more comprehensive test beyond the standard panel, there is a possibility that tizanidine might be detected.
There are reports of tizanidine causing false positives for amphetamines in drug tests.
For example, a user on reported failing a drug screen test while taking tizanidine, which showed up as amphetamines. Another source mentions that tizanidine, due to its chemical structure similarities to clonidine, may cause false positives for benzodiazepines. Additionally, tizanidine mixed with other chemicals, such as tramadol, may cause false positives for THC.
In terms of case studies, one individual reported taking a 4 mg dose of tizanidine six days before a pre-employment hair follicle test and was concerned about it showing up.
Another user mentioned that tizanidine is only looked at in about 1% of the samples tested, typically in parole and pain management cases.
Overall, while tizanidine is not commonly tested for in standard drug screens, it can potentially cause false positives or interfere with the accuracy of drug tests under certain circumstances. It is essential for individuals taking tizanidine to inform their employers or testing authorities about their prescription to avoid any potential issues.

Ultimately, it’s crucial to prioritize open communication with your healthcare provider and testing authorities to ensure that you receive accurate results and avoid any potential issues related to tizanidine use.
