Hello,
I think you should not get over-anxious. If you feel drowsy, then, take your time to get better, get a nap if you need.
However, if this will impair your daily functioning and activities, then, should stop taking
oxycodone.
Have more water to increase the speed of
flushing oxycodone earlier form your body.
Again, nothing to worry, not too much dose. But, as you have not been used to this medication, and perhaps the pain was not that bad, so this pill got a lot of effect and succeeded to reduce the pain but with a bit of side effects. They will get better for sure. Just follow the advice as given above.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
