This medication is used for the short-term treatment of moderate to severe pain. It contains 2 pain relievers: oxycodone and ibuprofen. Oxycodone is an opioid (narcotic) pain reliever that acts on certain parts of the brain to relieve pain. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that works by blocking a certain natural substance in your body to reduce pain and swelling.

Kidney problems can sometimes occur with the use of NSAID medications, including ibuprofen. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.
This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Avoid alcoholic beverages.
Before having surgery, tell your doctor or dentist that you are using this medication.
This medicine may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcohol and stop smoking. Consult your doctor or pharmacist for more information.
This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths or sunlamps. Use a sunscreen and wear protective clothing when outdoors.
Older adults may be more sensitive to the side effects of this drug, especially slow/shallow breathing, drowsiness, dizziness, confusion, stomach bleeding, and kidney problems.
Before using this medication, women of childbearing age should talk with their doctor(s) about the risks and benefits (such as miscarriage, trouble getting pregnant). Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It is not recommended for use during the first and last trimesters of pregnancy due to possible harm to the unborn baby and interference with normal labor/delivery.

This medication passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some of the products that may interact with this drug include: aliskiren, ACE inhibitors (such as captopril, lisinopril), angiotensin II receptor blockers (such as losartan, valsartan), certain cancer drugs (mercaptopurine, methotrexate, pemetrexed), cidofovir, cimetidine, corticosteroids (such as prednisone), desmopressin, lithium, mifepristone, certain pain medications (mixed opioid agonist-antagonists such as pentazocine, nalbuphine, butorphanol), naltrexone.
This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.
Other medications can affect the removal of oxycodone from your body, which may affect how oxycodone works. Examples include azole antifungals (such as ketoconazole), macrolide antibiotics (such as erythromycin), HIV medications (such as ritonavir), rifamycins (such as rifabutin, rifampin), certain drugs used to treat seizures (such as carbamazepine, phenytoin), among others.
Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (including aspirin, NSAIDs such as celecoxib, ketorolac, or naproxen). These drugs are similar to ibuprofen and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin for heart attack or stroke prevention (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Daily use of ibuprofen may decrease aspirin's ability to prevent heart attack/stroke. Talk to your doctor about using a different medication (such as acetaminophen) to treat pain/fever. If you must take ibuprofen, talk to your doctor about possibly taking immediate-release aspirin (not enteric-coated/EC) while taking ibuprofen. Take ibuprofen at least 8 hours before or at least 30 minutes after your aspirin dose. Do not increase your daily dose of aspirin or change the way you take aspirin/other medications without your doctor's approval.
The risk of serious side effects (such as slow/shallow breathing, severe drowsiness/dizziness) may be increased if this medication is taken with other products that also affect breathing or cause drowsiness. Therefore, tell your doctor or pharmacist if you are taking other products such as alcohol, anti-seizure drugs (such as phenobarbital), medicine for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, other narcotic pain relievers (such as codeine, oxymorphone), and psychiatric medicines (such as thioridazine, risperidone, amitriptyline, trazodone). Your medications or doses of your medications may need to be changed.
Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
This medication may interfere with certain laboratory tests (including amylase and lipase levels), possibly causing false test results. Make sure laboratory personnel and all your doctors know you use this drug.
If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: slowed or shallow breathing, slow heartbeat, excessive drowsiness, persistent dizziness/fainting, cold/clammy skin, limp/weak muscles, seizures, or loss of consciousness.
