Norco is a combination medication that contains two active ingredients: hydrocodone bitartrate (an opioid pain reliever) and acetaminophen (a non-opioid pain reliever and fever reducer). It is prescribed for the short-term management of moderate to moderately severe pain. Norco is available in various formulations, including tablets and oral solutions. Norco is primarily used to relieve moderate to moderately severe pain, such as pain due to surgery, injuries, or certain medical conditions.
