OXYCODONE IS A NARCOTIC PAIN MEDICINE SIMILAR TO MORPHINE. NARCOTIC PAIN MEDICINES ARE SOMETIMES ABUSED. DO NOT SHARE OXYCODONE WITH ANYONE ELSE. Oxycodone is only used for around-the-clock treatment of moderate or severe pain. It should not be used to treat occasional pain. If you have taken a monoamine oxidase inhibitor (MAOI) (such as phenelzine) within the past 14 days, TELL YOUR DOCTOR BEFORE YOU BEGIN to take Oxycodone.
