How strong or weak is phenobarbital compared to Xanax?

Evening Angela711; This is a tough one you really can't compare a Benzodiazepine meaning Xanax vs the old type sedative of barbiturate that Phenobarbital Really lots of people still take phenobarbital and if you have a doctor that would work with you See if he or she will give you enough Phenobarb to last until your next appt. and if that does not help much then go to the Xanax one thing for sure after being on Xanax for a while you get very dependent on it and it takes a while to get off. but anyway talk with the doctor.
