Hi Linda, All he's done is convet you from taking short acting 8 mg tabs of hydromorphone every 4 hours to 24 mgs of purdus 12 hour ime release version. You should actually do better at night, please let us know if lasts 12 hours? Others have asked and we don't have that many canadian posters.
I can give you Pudues canadian site where you can read the patient info on HMC.
Take care, Dave

Hey linda, They swithed the med in my pump from morphine to hydromorphone for a couple reasons a moth ago, It took a couple of adjustments but it's now working very well. Because it's stronger mg:mg I can go 85 days beteen refills rather than 28. It doesn't seem to have near the side effects of morphine other than constipation, I made Yakima fruit paste and I haven't needed any OTC or prescription meds for that any longer. The anxiety is likely from a hystamine release, In the US they use one of the antihytamines that also help with nausea, itching and anxiety, Visterill or Phenergan.
With less side effects, I've goten better pain relief from HM just the little problem with BT meds
