HI, thanks for using healthcare magic
All pain medications in the opiate family of drugs can potentially cause
drowsiness, this is a side effect that they have in common with each other.
This would include tramadol, codeine,
hydrocodone,
oxycodone (your medication), pethidine etc
Medications in the NSAIDs family eg arcoxia, celebrex,
ibuprofen, naproxen, cataflam, do not cause drowsiness , so you can consider one of these.
Another option would be a combination of an NSAID along with an opiate.
That way, the dose of the opiate would be reduced , so you would have reduced drowsiness.
I hope this helps
