If you're in a better system than I am, it's worth a shot. If the communication between your doc, wherever you get bloodwork done, and the pharmacy you go to is a clusterf**k (like me) then yeah it's probably best to stay away from clozaril.
I personally think it's better to at least try the rexulti first. I'm no doc, but Clozaril is last resort for a reason.
