Quick overview

Oxymorphone Tablet (oxymorphone hydrochloride) is a strong prescription opioid pain medicine. It comes as an immediate-release tablet for short-term pain and an extended-release tablet for long-term, around-the-clock pain control. It works on opioid receptors in the brain and spinal cord to change how the body senses and responds to pain. This medicine can be habit-forming and must be used exactly as prescribed.

What is Oxymorphone Tablet

Oxymorphone is a strong prescription opioid (narcotic) pain medicine. It comes as an immediate-release tablet for short-term pain and as an extended-release tablet for long-term, around-the-clock pain control.

Oxymorphone Tablet uses

  • Relieving severe pain that needs an opioid pain medicine
  • Managing short-term (acute) pain (immediate-release tablets)
  • Managing severe, ongoing pain that requires daily opioid treatment over an extended period (extended-release tablets)

Benefits of Oxymorphone Tablet

  • Provides strong relief for pain that other pain medicines do not control well enough or that cannot be tolerated
  • Extended-release form gives steady pain control over a 12-hour dosing interval

How Oxymorphone Tablet works

Oxymorphone works by changing the way the body senses and responds to pain, acting on opioid receptors in the brain and spinal cord.

Oxymorphone Tablet dosage

Take immediate-release tablets on an empty stomach, at least 1 hour before or 2 hours after meals. Take extended-release tablets on an empty stomach, at least 1 hour before or 2 hours after meals.

Take immediate-release tablets as needed for pain at the prescribed interval. Take extended-release tablets twice daily at the same times every day. Swallow extended-release tablets whole; do not break, chew, dissolve, crush, snort, or inject them. Take extended-release tablets one at a time; do not pre-soak, lick, or wet the tablet before placing it in your mouth.

Do not take more of this medicine or take it more often than your doctor prescribed. Do not stop taking this medicine suddenly without talking to your doctor; your dose will usually be lowered gradually. Continue your normal diet unless your doctor tells you otherwise.

If you miss a dose of the regular-schedule medicine, take it as soon as you remember unless it is almost time for the next dose, then skip the missed dose. Do not take a double dose to make up for a missed one. Older adults may be more sensitive to this medicine and should use it with care.

Warnings and precautions

  • Oxymorphone can cause serious or life-threatening breathing problems, especially in the first 72 hours of treatment or whenever your dose is increased. 
  • Even one dose of this medicine can be deadly if taken by someone else or by accident, especially by children. Store it safely and keep it out of reach of children and pets.
  • This medicine can be habit-forming. Take it exactly as prescribed; do not take more, more often, or stop suddenly without your doctor's guidance. 
  • Combining oxymorphone with other opioids, benzodiazepines, alcohol, or street drugs can cause severe drowsiness, slowed breathing, coma, and death.
  • Never give your oxymorphone to anyone else, even if they have similar symptoms. It is against the law and could cause their death. 
  • Extended-release tablets must be swallowed whole. Chewing, breaking, crushing, or dissolving them can release too much medicine at once and cause dangerous side effects or death.
  • Ask your doctor about having naloxone or nalmefene on hand, medicines that can reverse a life-threatening opioid overdose in an emergency.
  • Tell your doctor if you are pregnant or plan to become pregnant. Taking oxymorphone regularly during pregnancy can cause life-threatening withdrawal symptoms in the newborn baby if not recognized and treated.
  • Oxymorphone passes into breast milk and may harm your baby. Watch infants closely for increased sleepiness, breathing difficulties, or limpness, and get medical help right away if these occur.
  • Tell your doctor if you have kidney disease before taking this medicine. Tell your doctor if you have liver disease, as this may affect whether you should take oxymorphone.
  • Do not drink alcohol or use products containing alcohol while taking oxymorphone. Combining alcohol with this medicine can cause unsafe or deadly effects, including breathing problems and overdose.
  • This medicine may make you drowsy, dizzy, or lightheaded. Do not drive or operate machinery until you know how it affects you.

  • Keep this medication in the container it came in, tightly closed, and out of reach of children, and in a location that is not easily accessible by others, including visitors to the home

  • If a take-back program is not available, flush any medication that is outdated or no longer needed down the toilet so that others will not take it
  • Talk to your pharmacist about the proper disposal of your medication

When to see a doctor

  • Get emergency help right away if you have slow, shallow, or troubled breathing. Get medical help right away if you feel very sleepy, very dizzy, or pass out, or if someone taking this medicine does not respond or will not wake up.
  • Seek emergency care for signs of an allergic reaction, such as rash, hives, itching, swelling of the face, lips, tongue, or throat, or trouble breathing or swallowing. 
  • Call your doctor right away if you notice signs of serotonin syndrome, including agitation, confusion, hallucinations, fever, fast heartbeat, muscle twitching or stiffness, seizures, shaking, heavy sweating, or severe stomach upset.
