Norco Overdose: Call your doctor immediately in case of a known or suspected overdose. If the person can’t be awakened, has had a seizure, or has trouble breathing, call 911. Symptoms of Norco overdose may include narrowed or widened pupils; slowed, irregular, or stopped breathing; slowed, irregular, or stopped heartbeat; cold, clammy skin; excessive sleepiness or unresponsiveness; and seizures. 

While taking a product that contains hydrocodone, talk to your doctor about having a rescue medication called naloxone readily available in your home and office. Naloxone is used to reverse the life-threatening effects of an opioid overdose. You will need to make sure people in your household know how to recognize an overdose, how to use naloxone, and what to do until EMS arrives should an overdose occur.

NOTE: Norco is a prescription drug intended to be used only by the respective owners. Never share your prescription medication with others or use someone else’s Norco.
