Vicodin is a prescription medication that combines hydrocodone and acetaminophen, used to manage moderate to severe pain. It works by altering the brain’s perception of pain while providing anti-inflammatory benefits. Vicodin is often prescribed after surgery or for chronic pain conditions. While effective, it carries a risk of addiction and misuse due to its opioid component. Side effects may include drowsiness, dizziness, and gastrointestinal issues.
