What happens if I miss a dose (Opana, Opana ER)?
Since oxymorphone is sometimes used as needed, you may not be on a dosing schedule. If you are using the medication regularly, take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.
Extended-release oxymorphone is not for use on an as-needed basis for pain.
What happens if I overdose (Opana, Opana ER)?
Seek emergency medical attention if you think you have used too much of this medicine. An overdose of oxymorphone can be fatal.
Overdose symptoms may include extreme drowsiness, pinpoint pupils, confusion, cold and clammy skin, weak pulse, shallow breathing, fainting, or breathing that stops.
What should I avoid while using oxymorphone (Opana, Opana ER)?
Do not drink alcohol while you are using oxymorphone. Dangerous side effects or death can occur when alcohol is combined with oxymorphone. Check your food and medicine labels to be sure these products do not contain alcohol.

What other drugs will affect oxymorphone (Opana, Opana ER)?
Do not take oxymorphone with other narcotic pain medications, sedatives, tranquilizers, muscle relaxers, or other medicines that can make you sleepy or slow your breathing. Dangerous side effects may result.
Before taking oxymorphone, tell your doctor if you are using pentazocine (Talwin), nalbuphine (Nubain), butorphanol (Stadol), or buprenorphine (Buprenex, Subutex). If you are using any of these drugs, you may not be able to use oxymorphone, or you may need dosage adjustments or special tests during treatment.
This list is not complete and there may be other drugs that can interact with oxymorphone. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
