Not a controlled drug
Thanks for the query
Nubain is a semi synthetic opiod analgesic
and it is not controlled by the Controlled Substance act.
I suggest you to use Nubain if you feel it is better over Tramadol
. The analgesic effect of Nubain is seen within 3 minutes and it is as effective as Tramadol or codeine
. However doctors might be worried that you might become dependent on Nubain and they want to use lesser potent analgesics so that in case of a severe attack more potent ones can be used.
Availability of Nubain is also another issue as many doctors have stopped prescribing this drug as better drugs are available in the market.
I hope I was of help
