Chronic Pain
"I have been taking oxycodone, 15mg tabs, 4 times a day, for a couple of years, for severe joint, neck, &amp; back pain.  My Doctor says this is the maximum dose for the drug.  I am a 300 pound, 5&#039; 6&#039;&#039;, 75 year old, male.  The medicine works at about 85% to 90% level, for about 4 hours for me.  I think I need to increase the dose to every 4 hours or 6 hours a day or move up to 20mg tablets."
