What Is Mayne Pharma Oxycodone IR Used For?
Mayne Pharma Oxycodone IR contains oxycodone hydrochloride, a powerful pain medication that belongs to a group of medicines called narcotic analgesics.
Primary Uses
This medication is used for the short-term management of severe pain when other treatment options are not able to effectively manage your pain or you cannot tolerate them.
How It Works
The active ingredient works by binding to receptors called opioid receptors in your central nervous system. This binding action changes your body’s perception of pain throughout the central nervous system, producing the pain relieving effect.
