"i take the generic form (pentazocine-naloxone tablet). i have fibromyalgia. i moved to ga around 3 yrs ago and luckily my last pain management physician was able to refer me to a doctor in a nearby town.  i travel 132 miles round trip to him monthly. at the point of seeing him i was in real bad pain and he prescribed naloxone/pentazocaine generic. this medication has helped me i take a steady 1 to 2 every 4 hours.  it is more rare now to take 2.  i know it is masking the pain and it does not mess with my head.  i can get into major pain at times. it passes, i think easier because i have a steady level in my system."
