Yes: If they are testing for benzodiazepines, this drug will show up. Most basic drug testing panels will test for benzodiazepines. If you inform your doctors of all of your medications, you should be fine. This is a common medication for muscle spasm.

As a tricyclic: Cyclobenzaprine is not chemically similar to benzodiazepines, which include drugs such as xanax, (alprazolam) ativan, valium, and klonopin. There should be no cross reactivity between cyclobenzaprine and benzodiazepines on drug testing. Cyclobenzaprine is chemically similar to tricyclic antidepressants, such as Elavil (amitriptyline). Some panels for substances of abuse do include tests for tricyclics.
