There is zero difference whatsoever between brand and generic for any drug. Pharmacies, insurance componies, and sometimes doctors, will often recommend brand because it supports big pharmaceutical corporations who make it. There's literally no difference at all, except the fillers and binders, which have no effect on your brain or body when taking it orally. Now, if it was a brand containing multiple drugs vs. Generic containing only one, that would be different, but klonopin doesn't come in any pills containing other drugs. An example of this would be percocet (oxycodone and acetominophen) vs. Generic oxycodone. Tell her to just buy the generic
