That's right. Double check the imprint. Your pill sounds like
Oxycodone 15 mg (immediate release) made by Amide. The imprint is an A not an R.
A 214 is
OXYCODONE 15 MG
which is a generic version of
Roxicodone (immediate release oxycodone)
Note that
OxyContin is an extended-release formulation of oxycodone.
Imprint Code A 214
Description green, round, scored tablet
