i am taking 100 mg. a day and wonder what is the max for an adult.
The question as I understand it isn't necessarily the amount of oxycodone that you're taking but the amount of acetaminophen that's often comes with the drug. In general - and it appears this may be coming down - the maximum amount of acetaminophen a healthy person with no liver problems should take is 4 mgs a day.
If you're not taking oxycodone with acetaminophen then the maximum allowed amount can be quite high. There is a tablet of oxycodone that contains 160 mgs. of the drug. I don't know the maximum daily dose of the drug; it depends on possibility of being addicted, etc. Your pharmacist might be a good resource for that.
