Naloxone / pentazocine
"I am prescribed to Talwin NX for chronic left leg pain due to having numerous strokes, seizures, and two heart-attacks. I have also been diagnosed with Crohn's disease. I think this medication works very well and when I don't take it for awhile I have no adverse reactions-(withdrawals).I have also not formed a dependency to this medication unlike other narcotic pain medications I have been prescribed."
