Key takeaways
Fentanyl and Norco are both used to manage pain, but they have some key differences. Fentanyl is a powerful opioid available as a transdermal patch, used for severe, long-term pain in people who are already opioid-tolerant. It works by releasing medication through your skin over 72 hours. Norco, on the other hand, is a combination of hydrocodone (an opioid) and acetaminophen (an analgesic) taken orally for pain that isn't relieved by non-opioid medications. Norco starts working within 30 minutes and is taken every 4 to 6 hours as needed. Fentanyl is only available as a generic, while Norco's brand name is discontinued but generics are available. Both medications carry risks of addiction, misuse, and serious side effects like slowed breathing, but fentanyl requires special monitoring under the Risk Evaluation and Mitigation Strategy (REMS) program due to its high potency and risk profile. Norco also has a risk of liver damage due to its acetaminophen content, which is not a concern with fentanyl.
