Which is stronger vicoden 500 mg or 325 mg?

the "5" portion means that there is 5mg of hydrocodone in the product. it does not matter that it is vicodin or norco, both contain hydrocodone. the difference is that vicodin products usually contain a ratio of 1:100 hydrocone to acetaminophen( example 5/500 or 7.5/750) where Norco may have 5 or 10 mg hydrocodone but usually not more than 325mg acetaminophen(example 5/325 or 10/325). Generally Norco may have less acetaminophen overall regardless of the hydrocodone content. People who will need hydrocodone for longer periods may be better off with the lower amount of acetaminophen in Norco due to the potential organ toxicity of acetaminophen. Acetaminophen is in a class of drugs known as NSAIDs - non steroidal anti-imflammatory drugs, such as Tylenol. Hydrocodone products require a prescription whereas acetaminophen, like Tylenol, can be purchased over the counter. Why pharmaceutical manufacturers include the acetaminophen component with the hydrocodone is not made clear to the consumer but people with liver problems might be safer with less acetaminophen injestion. This information should be confirmed with your physician for accuracy and correctness.
