Question about a muscle relaxer (Chlorzoxazone)

[FN57]

Some background info first. I've taken over the course of my life every muscle relaxer there is besides dantrolene. Now to my question, I've got these chlorzoxazone tablets (500mg) and the info im gathering is kinda sketchy. All i wanna know is can i take a higher dose than 750mg AT ONCE without any kind of liver or kidney damage. Its straight up chlorzoxazone no acetaminophen in it. You'll find the same info i did if you use google which basically says dont take more than 750mg at once but alot of dosage info for drugs say this and that and you end up high and fine. I know this medication is the oddball of muscle relaxers and I've never gone above 750mg in a single dose due to fear of liver damage so if anyone can safely give me a green light on maybe doubling the dose and not put my health in jeopardy id appreciate it
