Norco contains a combination of acetaminophen and hydrocodone. Hydrocodone is an opioid pain medication. An opioid is sometimes called a narcotic. Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone.
Norco is used to relieve moderate to moderately severe pain.
Norco may also be used for purposes not listed in this medication guide.
Hydrocodone can slow or stop your breathing. Never use Norco in larger amounts, or for longer than prescribed. Narcotic pain medicine may be habit-forming, even at regular doses. Never share Norco with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Do not use Norco if you have used a MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.
An overdose of acetaminophen can damage your liver or cause death. Call your doctor at once if you have nausea, pain in your upper stomach, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of your skin or eyes).
Stop taking Norco and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.

Some medicines can interact with hydrocodone and cause a serious condition called serotonin syndrome.
