Notice:

FDA Drug Safety Communication:

[Posted 4/13/2023]

  • As part of its ongoing efforts to address the nation's opioid crisis, FDA is requiring several updates to the prescribing information of opioid pain medicines. The changes are being made to provide additional guidance for safe use of these drugs while also recognizing the important benefits when used appropriately. The changes apply to both immediate-release (IR) and extended-release/long-acting preparations (ER/LA).
  • Updates to the IR opioids state that these drugs should not be used for an extended period unless the pain remains severe enough to require an opioid pain medicine and alternative treatment options are insufficient, and that many acute pain conditions treated in the outpatient setting require no more than a few days of an opioid pain medicine.
  • Updates to the ER/LA opioids recommend that these drugs be reserved for severe and persistent pain requiring an extended period of treatment with a daily opioid pain medicine and for which alternative treatment options are inadequate.
  • A new warning is being added about opioid-induced hyperalgesia (OIH) for both IR and ER/LA opioid pain medicines. This includes information describing the symptoms that differentiate OIH from opioid tolerance and withdrawal.
  • Information in the boxed warning for all IR and ER/LA opioid pain medicines will be updated and reordered to elevate the importance of warnings concerning life-threatening respiratory depression, and risks associated with using opioid pain medicines in conjunction with benzodiazepines or other medicines that depress the central nervous system (CNS).
  • Other changes will also be required in various other sections of the prescribing information to educate clinicians, patients, and caregivers about the risks of these drugs.

IMPORTANT WARNING:

Oxymorphone may be habit forming, especially with prolonged use. Take oxymorphone exactly as directed. Do not take a larger dose, take it more often, or take it for a longer period of time, or in a different way than prescribed by your doctor. While taking oxymorphone, discuss with your health care provider your pain treatment goals, length of treatment, and other ways to manage your pain. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or has had an overdose, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse oxymorphone if you have or have ever had any of these conditions. Talk to your healthcare provider immediately and ask for guidance if you think that you have an opioid addiction or call the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-HELP.

Oxymorphone may cause serious or life-threatening breathing problems, especially during the first 72 hours of your treatment and any time your dose is increased. Your doctor will monitor you carefully during your treatment. Tell your doctor if you have or have ever had slowed breathing, or asthma. Your doctor will probably tell you not to take oxymorphone tablets. Also tell your doctor if you have or have ever had lung disease such as chronic obstructive pulmonary disease (COPD; a group of lung diseases that includes chronic bronchitis and emphysema), a head injury, brain tumor, any condition that increases the amount of pressure in your brain, or sleep apnea (condition in which breathing stops or becomes shallow during sleep). The risk that you will develop breathing problems may be higher if you are an older adult or are weak or malnourished due to disease. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.

Taking certain medications other medications with oxymorphone may increase the risk that you will develop serious or life-threatening breathing problems, sedation, or coma. Tell your doctor and pharmacist if you are taking or plan to take any of the following medications: benzodiazepines such as alprazolam (Xanax), chlordiazepoxide (Librium), clonazepam (Klonopin), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), oxazepam, temazepam (Restoril), and triazolam (Halcion);medications for mental illness or nausea; other narcotic pain medications; muscle relaxants; sedatives; sleeping pills; and tranquilizers. Also tell your doctor or pharmacist if you are taking any of the following medications or have stopped taking them within the past 2 weeks: monoamine oxidase (MAO) inhibitors such as isocarboxazid (Marplan), linezolid (Zyvox), phenelzine (Nardil), rasagiline (Azilect), selegiline (Emsam, Eldepryl, Zelapar), and tranylcypromine (Parnate).Your doctor may need to change the doses of your medication and will monitor you carefully. If you take oxymorphone with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.

Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with oxycodone increases the risk that you will experience serious, life-threatening side effects. Do not drink alcohol, take prescription or nonprescription medications that contain alcohol, or use street drugs during your treatment.

Do not allow anyone else to take your medication. Oxymorphone may harm or cause death to other people who take your medication, especially children. Store oxymorphone in a safe place so that no one else can take it accidentally or on purpose. Be especially careful to keep oxymorphone out of the reach of children. Keep track of how many tablets, or capsules are left so you will know if any medication is missing.

Tell your doctor if you are pregnant or plan to become pregnant. If you take oxymorphone regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.

Talk to your doctor about the risks of taking oxymorphone.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with oxymorphone and each time you fill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

Why is this medication prescribed?

Oxymorphone is used to relieve moderate to severe pain in people whose pain is not controlled 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 as an extended-release (long-acting) tablet to take by mouth on an empty stomach, at least 1 hour before or 2 hours after meals. It is usually taken every 4 to 6 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.

Swallow the extended-release tablets whole; do not chew or crush them.

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.

Do not stop taking oxymorphone without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking oxymorphone, you may experience withdrawal symptoms such as restlessness; watery eyes; runny nose; yawning; sweating; chills; muscle, joint, or back pain; enlarged pupils (black circles in the centers of the eyes); irritability; anxiety; weakness; stomach cramps; difficulty falling asleep or staying asleep; nausea; vomiting; diarrhea; loss of appetite; fast heartbeat; and fast breathing.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). You must immediately dispose of any medication that is outdated or no longer needed through a medicine take-back program. If you do not have a take-back program nearby or one that you can access promptly, 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.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

In case of emergency/overdose

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

While taking oxymorphone, you should talk to your doctor about having a rescue medication called naloxone readily available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. Your doctor may also prescribe you naloxone if you are living in a household where there are small children or someone who has abused street or prescription drugs. You should make sure that you and your family members, caregivers, or the people who spend time with you know how to recognize an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer's website to get the instructions. If symptoms of an overdose occur, a friend or family member should give the first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.

Symptoms of overdose may include the following:

  • difficulty breathing or slow or shallow breathing
  • bluish-tinged skin, lips, or fingernails
  • cold, clammy skin
  • increase or decrease in pupil (dark circle in the eye) size
  • limp or weak muscles
  • extreme sleepiness
  • unusual snoring
  • slowed heartbeat
  • unable to respond or wake up

What other information should I know?

Keep all appointments with your doctor.

This prescription is not refillable. If you are taking oxymorphone to control your pain on a long term basis, be sure to schedule appointments with your doctor regularly so that you do not run out of medication. If you are taking oxymorphone on a short term basis, call your doctor if you continue to have pain after you finish the medication.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
