(Hydrocodone Bitartrate and Acetaminophen)
Norco is primarily used to treat pain that is severe enough to warrant opioid medications and is unable to be treated by other pain medications.
Norco acts similarly to other opioid agonists. The hydrocodone binds to several opiate receptors in the central nervous system. It stimulates a process that reduces the excitability of the neurons in the brain and spinal cord. In this way, it changes the perception of pain in the person. Opioid agonists can also produce experiences of euphoria, which can lead to misuse and abuse.
Norco pills also contain acetaminophen. The exact mechanism of action of acetaminophen relieving pain is unknown, but it is thought that it works in the central nervous system to increase a person’s pain threshold by impairing certain enzymes involved in creating prostaglandins.
Uses of Norco
This combination medication is used to relieve moderate to severe pain. It contains an opioid (narcotic) pain reliever (hydrocodone) and a non-opioid pain reliever (acetaminophen). Hydrocodone works in the brain to change how your body feels and responds to pain. Acetaminophen can also reduce a fever.
This product is not recommended for use in children younger than 6 years due to an increased risk of serious side effects (such as slow/shallow breathing).
Overdose of Norco
If someone has overdosed and has serious symptoms such as passing out or trouble breathing, give them naloxone if available, then call 911. If the person is awake and has no symptoms, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222.
Canada residents can call a provincial poison control center. Symptoms of overdose may include: slow/shallow breathing, nausea, vomiting, loss of appetite, sweating, stomach/abdominal pain, extreme tiredness, slow heartbeat, yellowing eyes/skin, dark urine, coma.
