The whole point of Low Dose Naltrexone is to achieve pain relief without side effects. I don't think increasing the dosage is supposed cause greater pain relief. What you're taking seems to be a variation of the same type of med.

Your original dosage by patch is probably stronger than Low Dose Naltrexone.

This link has info about both Low Dose Naltrexone and the idea that opiates can increase pain. (What you were on is a synthetic opiate.)
