What is Opana ER (oxymorphone)?
Oxymorphone is an opioid pain medication. An opioid is sometimes called a narcotic.
Oxymorphone is used to treat moderate to severe pain.
The extended-release form of this medicine is for around-the-clock treatment of pain. This form of oxymorphone is not for use on an as-needed basis for pain.
Oxymorphone may also be used for purposes not listed in this medication guide.
What is the most important information I should know about Opana ER (oxymorphone)?
You should not use this medicine if you have severe asthma or breathing problems, a blockage in your stomach or intestines, or moderate to severe liver disease.
Oxymorphone can slow or stop your breathing, and may be habit-forming. Use only your prescribed dose, and swallow an extended-release pill whole to avoid a potentially fatal dose. Never share oxymorphone with another person.
MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Oxymorphone may cause life-threatening withdrawal symptoms in a newborn if the mother has taken this medicine during pregnancy.
Do not drink alcohol. Dangerous side effects or death could occur.
What should I discuss with my healthcare provider before using Opana ER (oxymorphone)?
You should not take this medicine if you are allergic to oxymorphone, or if you have:
severe asthma or breathing problems;
a blockage in your stomach or intestines; or
moderate to severe liver disease.
Some medicines can interact with oxymorphone and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
To make sure oxymorphone is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
a history of head injury, brain tumor, or seizures;
a history of drug abuse, alcohol addiction, or mental illness;
liver or kidney problems;
problems with your gallbladder, pancreas, or thyroid; or
if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others).
Tell your doctor if you are pregnant or plan to become pregnant. If you use oxymorphone while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks.
It is not known whether oxymorphone passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How should I use Opana ER (oxymorphone)?
Follow all directions on your prescription label. Oxymorphone can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never use oxymorphone in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Oxymorphone may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away oxymorphone is against the law.
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.
Take oxymorphone on an empty stomach, at least 1 hour before or 2 hours after a meal.
Do not crush, break, or open an extended-release pill. Swallow it whole to avoid exposure to a potentially fatal dose.
Some forms of oxymorphone are made with ingredients that are not absorbed in the body. Part of the tablet may appear in your stool. This is a normal side effect of oxymorphone and will not make the medication less effective.
Do not stop using this medicine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using oxymorphone.
Never crush or break a oxymorphone pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death with the misuse of oxymorphone and similar prescription drugs.
Store at room temperature away from moisture, heat, and light.
Keep track of the amount of medicine used from each new bottle. Oxymorphone is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover oxymorphone pills. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush any unused pills 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 scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A oxymorphone overdose can be fatal, especially in a child or other person using the medicine without a prescription.
Overdose symptoms may include extreme drowsiness, muscle weakness, confusion, cold and clammy skin, pinpoint pupils, shallow breathing, slow heart rate, fainting, or coma.
What should I avoid while using Opana ER (oxymorphone)?
Do not drink alcohol. Dangerous side effects or death can occur when alcohol is combined with oxymorphone.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how oxymorphone will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
