I think you meant
methocarbaMol (Muscle Relaxant).

From reading the information on this drug, I am under the impression that it IS NOT a controlled substance.
I am NOT a doctor OR am in the medical field whatsoever but from the various sites I have seen in regards to this, I am going to ASSUME that it isn't.
Maybe someone else can shed some info on this.
