Oxycodone 40 mg is a high-dose prescription opioid analgesic formulated for the management of severe chronic pain in patients who require continuous, around-the-clock opioid therapy. It is not intended for occasional or short-term pain relief, but rather for individuals who are already opioid-tolerant and need strong, sustained relief from conditions such as advanced cancer, spinal injuries, post-surgical complications, or degenerative joint diseases.
