What you could do is ask your doctor for a medication that has hydrocodone but not the acetominaphen(tylenol) that's what could be fatal to your liver and or kidneys, the hydrocodone
is not nearly as hard on the liver as tylenol. Your vicodin has 5mg
of hydrocodone and 500mg acetaminophen(tylenol) you might try norco(10mg hydrocodone/2-300mg tylenol) or just ask the dr. for a medication without the tylenol b/c most opiate medications have a lot of tylenol in them. I also like vicoprofen(7.5mg.
