morphine sulfate pentahydrate. Morphine belongs to a group of medicines called opioid
analgesics. It acts in the central nervous system by blocking pain and your emotional
response to pain.

MORPHINE MR APOTEX tablets you may experience some symptoms of withdrawal.
It is important that you discuss this issue with your doctor and take the medicine
exactly as directed by your doctor.
