Oxycodone and OxyContin are opioid pain medications with similar active ingredients but different formulations. Oxycodone is typically immediate-release, providing quick relief for moderate to severe pain, while OxyContin is extended-release, designed for long-lasting pain control over 12 hours. Both can cause drowsiness, constipation, and euphoria, and carry high risks of dependence and overdose if misused. Choosing between them depends on pain severity, duration, and medical guidance. Proper use, dosing, and monitoring are essential to maximize relief while minimizing side effects and addiction risk, ensuring safe and effective pain management.
