Will oxycodone be out of my system in 24 days?

24 to 72hr: It's gone within 24 hrs if taken occasionally. If regular use approx 72 hours. Variability exist due to age and medical history.

It depends on type: Oxycodone comes in two varieties. Immediate release (ir) and controlled release (cr). Some companies mix oxycodone (usually the ir variety) with Acetaminophen and give it names such as percocet, endocet, tylox (oxycodone and acetaminophen). The ir is taken once per 4 -6 hours and can stay in your system for about a day but may be detected up to 72 hr later cr is taken every 12 hours and can stay in your system 3 -4 days.
