The normal dosage for Norco 10/325 is one tablet every four to six hours for adults, depending on their pain levels, according to Drugs.com. Patients should not take more than six tablets per day. The drug's generic name is hydrocodone bitartrate 7.5 milligrams, acetaminophen 325 milligrams.
Norco 10/325 combines the powerful opioid hydrocodone with acetaminophen, a weaker pain medication that boosts hydrocodone's pain relief capability, notes Drugs.com. Taking an opioid, such as hydrocodone, for an extended period can cause patients to become addicted to the drug. Patients should use acetaminophen with caution as overdosing can damage the liver or lead to death. Overdose symptoms, such as nausea, upper gastric pain, darkened urine and jaundiced eyes or skin, demand immediate medical attention.
