They last about the same amount of time but percs are superior because they are oxycodone and loritabs are hydrocodone. If i were you I would take 25-30mg of oxycodone and dose up with 15mg of hydrocodone as soon as you start to come down. If you're sensitive to opiates you might want to watch your dose and be sure not to take to much acetaminophen (not more than 4000mg of APAP per 24hours or your liver will be damaged.) Do not combine acetaminophen with alcohol as that is the leading cause of liver damage in the US. Post edited at 4:19 pm on Nov. 8, 2009 by pantsman000
