Norco 10-325 mg is a prescription medication commonly used to manage moderate to severe pain. It contains two active ingredients: hydrocodone (10 mg), an opioid pain reliever, and acetaminophen (325 mg), a non-opioid pain reliever often found in over-the-counter products like Tylenol. This combination works by both changing how the brain perceives pain and reducing inflammation and fever, making it more effective than either ingredient alone. Because it contains an opioid, Norco is classified as a controlled substance with a potential risk of dependence, misuse, or addiction. For this reason, doctors usually prescribe it only when other pain treatments are not sufficient. When taken exactly as directed, Norco can provide important relief for patients recovering from surgery, injuries, or other painful medical conditions.
