restless legs syndrome
"I had been on generic ropinirole for months and because it was so effective I tolerated severe nausea, nasal congestion, hiccups and flushing because I was desperate to sleep.  When I talked to my neuro he had me switch to name brand based on side effects and it was so bizarre.  The drug works great and with zero side effects.  He said the dosing range that generics are allowed to meet is much too large for some of the neurology drugs and because pharmacy plans frequently switch which generic manufacturer they use it is impossible to avoid dosage problems as well.  The issue for me was also one of side effects from additives that were not in brand Requip but were in the generic.  Hope this helps someone."
