WHY is this medicine prescribed?
Oxymorphone is used to relieve moderate to severe pain. Oxymorphone extended-release tablets are used to relieve severe pain in people who are expected to need pain medication around the clock for a long time and who cannot be treated with other medications. Oxymorphone is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the body responds to pain.

HOW should this medicine be used?
Oxymorphone comes as a tablet and an extended-release tablet to take by mouth on an empty stomach, at least 1 hour before or 2 hours after meals. The regular tablet is usually taken every 4 to 6 hours. The extended-release tablet is usually taken every 12 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take oxymorphone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are taking the extended-release tablets, swallow them one at a time with plenty of water. Swallow each extended-release tablet right after putting it in your mouth. Do not presoak, wet, or lick the tablets before you put them in your mouth.

Your doctor will probably start you on a low dose of oxymorphone and gradually increase your dose until your pain is controlled. Your doctor may adjust your dose at any time during your treatment if your pain is not controlled. If you feel that your pain is not controlled, call your doctor. Do not change the dose of your medication without talking to your doctor.
