How long does a 15mg oxycodone/roxicodone stay in your system for? Is it less or more then 3 days?

Not Medical Advice:

Less than 3 days.

Roxicodone 15 mg tab has a half-life of 3.55±1.0 hours, so a single dose will take about 25 hours to be eliminated. The half-life is the time necessary for the concentration of drug in the plasma to decrease by half.

About 60% to 87% of an oral dose of oxycodone reaches the systemic circulation in comparison to a parenteral dose. This high oral bioavailability (compared to other oral opioids) is due to lower presystemic and/or first-pass metabolism of oxycodone.

The relative oral bioavailability of Roxicodone® 15 mg and 30 mg tablets, compared to the 5 mg Roxicodone® tablets, is 96% and 101% respectively. Roxicodone® 15 mg tablets and 30 tablets are bioequivalent to the 5 mg Roxicodone® tablet.
