Ok so my wife has fibromyalgia she is prescribed oxycodone 30 mg 6 a day and hydromorphone 4 a day. The oxycodone is great for pain but the dilaudid doesn't work well at all. A friend of outs suffers from the same issue and is prescribed opana 40mg. Is opana a good substitute for the dilaudid?. We have tried lyrics and everything with no luck and also OxyContin op 40mg and those did work as good as the 30mg oxy. Will opana do the trick? Also was is the conversion of opana to oxy? Thank you
