Anyway, the half-life of Oxycodone (Percocet) is 3 - 4.5 hours. Now a lot of factors can increase this value (eg. if you suffer from renal failure, liver issues etc.) But assuming the worst, and let's say you have taken 20mg of Oxycodone. This means:
4.5 hours later - 10mg remaining
9 hrs later - 5mg remaining
13.5 hrs later - 2.5mg
18 hrs - 1.25mg
22.5 hrs - 0.625mg
27 hrs - 0.3125mg left
31.5 hours - 0.16mg left ----> by this point, you don't have to worry.

So all in all, to be on the safe side, keep this value at 36 hours but allow a buffer of upto 48 hours to be on the safe side since there are other factors to consider like your dosage and body-weight. Hope this helps.

It shouldn't matter what appears in your drug screening AS LONG AS YOU HAVE THE PROPER PRESCRIPTIONS FOR ALL YOUR MEDICATIONS. It is illegal for your boss to take disciplinary actions against you if your prescriptions match your test. If your boss does take actions against you and you are legit with all your RX's then you have a legal matter on your hands. Contact your state/lawyer for more legal advice. Good luck to you.....

I would check with the dr you should only take 1 every 4-6 hours recommended amount is 60 mg Max a day. I.take one 10mg 3x a day for cluster headaches also prescribed neurontin but rarely take it because it will also increase your chance of respiratory depression I take xaxax 0.5 only 2x a day even though I.am prescribed it 3x a day. Good luck

post said: and let's say you have taken 20mg of Oxycodone. This means:
4.5 hours later - 10mg remaining
9 hrs later - 5mg remaining
13.5 hrs later - 2.5mg
18 hrs - 1.25mg
22.5 hrs - 0.625mg
27 hrs - 0.3125mg left
31.5 hours - 0.16mg left ----> by this point, you don't have to worry.

when you say "9 hours later" on the seoncd line, do you mean 9 hours from the time of taking the med? or is it 9 hours from the 4.5 marker in the first line? meaning i would add the 9 hours to the 4.5 hours to get a total time of 13.5 hours when 5 mg is still remaining? thank yu!

It means 9 hours after the pill was taken. General rule for percocets being out of your system completely is 72 hours for high dose heavy users and others can be 24 to 36 hours with small doses.

10pm Sunday I took 20 my oxy after Detoxing for 3 days. Then Monday morning I took 5 more. I got called in for an interview. It's been 48 hours since the last dose, and I'm on my way to the drug screening. I've been drinking water like mad for 24 hours (at least 2 gallons) I need some encouragement. Anyone past a GC test after 48 hour?

The interesting thing about this is, is while "technically" 50% of the drug is still in my system, it does not seem to "help" in the pain relief when added together with the next dose. For instance. Say I take 10mgs at noon. Theoretically at 4:30pm, I should have 5mgs still in my system. So, I would have "thought", that if i took only another 5mgs then, within 25 minutes I should have the same 10mgs in my system as like I did at noon. However, I do NOT get the same amount of pain relief from adding the 5mgs to the 5mgs theoretically remaining, as I do if i take 10mgs all at once. Does the 50% left in your system after 4.5 hours no longer "help" in the pain relief if I add another 5 mgs to it? Does the med only "work" for pain relief for a certain amount of time for taking it. Thanks

So I took an generic Percocet A349 (which has 5mg of oxycodone in it) around 12:30-1:00am last night. I may have a drug test tomorrow around 9am, not sure if it's saliva or urine. Would I be safe? Or no?

Hi Mia. Would you be able to do the Half Life math for 25mg of oxycodone? I have a 10 MG percocet and 15mg of just oxycodone no aspirin. I usually take the pills Saturday as I have a UA on monday. But I have until 7:55pm to take the UA Monday. Last week I took 20mg of oxy. Within about an hour apart and came up clean on my mondays UA. I also just drank water that following Saturday until that Monday. And urinated a lot in between then. Please help.

Drug tests screen oxy at 50ng, I researched and is .00005 in mg. you need to give yourself 72/96 hours to clean and water never worked for me..
