Oxycodone 30mg is a strong prescription opioid used to treat severe pain, often prescribed when other pain relief methods are ineffective. It works by binding to opioid receptors in the brain, altering pain perception and providing significant relief. Due to its potency, it carries a high risk of dependence, overdose, and side effects like drowsiness or constipation. It should be used only as prescribed, under close medical supervision, to ensure safe and effective pain management.
