Can Skelaxin or Flexeril show up as a false positive for something else on a urine drug screen?

They will NOT show up on a drug test. They are not a controlled substance. They can however become habit forming which is why I recommend taking those medications as directed by your doctor to prevent abuse. Addiction to these medications are rare but can happen if not used as directed by your doctor. They will not show up in you drug test. Hope this eases your worries. Good Luck

There are so many people who have no idea what there talking about. Skelaxin will not show up unless specifically tested for, nor is it habit forming or controlled. Flexeril, on the other hand, can and will show up on some drug test as a tricyclic antidepressants, many panel tests do test for them now a days. They can be somewhat habit forming mentally and physically under some long term cases. Stopping this type of medication after long term heavy use may cause vomiting and possible headache. This is rare. They are currently not controlled under DEA and FDA guidelines. Some hospitals do look at Flexeril as a controlled substance due to its sedating effects. As long as you have those prescriptions, you should be fine either way.
