Oxymorphone is an opioid medication used to treat moderate to severe pain.
The extended-release form of oxymorphone is for around-the-clock treatment of pain and should not be used on an as-needed basis for pain.
Oxymorphone may also be used for purposes not listed in this medication guide.
MISUSE OF OPIOID MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.

You should not take oxymorphone if you are allergic to oxymorphone, or if you have:

a blockage in your stomach or intestines.
Tell your doctor if you have ever had:
drug or alcohol addiction, or mental illness;
liver or kidney problems; or
problems with your gallbladder, pancreas, or thyroid.

Do not breast-feed while taking oxymorphone.
How should I use oxymorphone?
Follow the directions on your prescription label and read all medication guides. Never use oxymorphone in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.

Always check your bottle to make sure you have received the correct pills (same brand and type) of medicine prescribed by your doctor. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.
Stop taking all other around-the-clock narcotic pain medications when you start taking oxymorphone.

Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
What happens if I miss a dose?
Since oxymorphone is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next dose. Do not use two doses at one time.
