How Long Does Metaxalone Stay In Your System

1 Topic Found

How long does Metaxalone 800 mg stay in your system? I have to take a drug test. I do have a prescription for it, but I would like to know for future reference. ## Metaxalone is a muscle relaxant, so it is not a drug that is included in standard drug tests. ## Thanks! That's good to know :-) ## U dont have to worry about a muscle relaxers when taking a drug test. U are prob gonna take a 5 panel drug test anyway unless they think you are using drugs or your about to get a job at a fortune 500 company. I only take random 5 panel tests for having a commercial drivers license. Pain killers do not even show up on a 5 panel test either. not even oxycontin. Those are all opioids and only pop on an 8 panel test or an higher panel test. Most all pills leave your system in less then 72 hours....
