This medication is used to help relieve severe ongoing pain (such as due to cancer). Oxycodone belongs to a class of drugs known as opioid analgesics. It works in the brain to change how your body feels and responds to pain.The higher strengths of this drug (more than 40 milligrams per tablet) should be used only if you have been regularly taking moderate to large amounts of an opioid pain medication.
Like all medicines, oxycodone can cause side effects in some people, but many people have no side effects or only minor ones.
The higher the dose of oxycodone the more chance that you will get side effects.
