Xartemis XR Consumer Information

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should give naloxone and/or seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction. Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.

Call your doctor at once if you have:

  • noisy breathing, sighing, shallow breathing, breathing that stops;
  • a light-headed feeling, like you might pass out;
  • weakness, tiredness, fever, unusual bruising or bleeding;
  • confusion, unusual thoughts or behavior;
  • problems with urination;
  • liver problems--nausea, upper stomach pain, tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
  • low cortisol levels-- nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness; or
  • high levels of serotonin in the body--agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, diarrhea.

Serious breathing problems may be more likely in older adults and in those who are debilitated or have wasting syndrome or chronic breathing disorders.

Common side effects include:

  • dizziness, drowsiness, feeling tired;
  • feelings of extreme happiness or sadness;
  • nausea, vomiting, stomach pain;
  • constipation; or
  • headache.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Clinical Studies Experience

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.

In safety data from two Phase 3 (one placebo-controlled, one open-label) trials where multiple doses of XARTEMIS XR were administered for up to 42 days, the most common adverse reactions (reported by ≥ 10% in any XARTEMIS XR dose group) were: nausea, dizziness and vomiting. The most common reasons for discontinuation due to AEs in these 2 studies (reported by ≥ 1% in any XARTEMIS XR dose group) were vomiting (4.8%) and nausea (4.1%); there were no reports of these adverse reactions in the placebo-treated patients.

A total of 1028 subjects in 14 clinical studies were treated with XARTEMIS XR during the clinical development program, including 892 subjects treated with 15 mg oxycodone and 650 mg acetaminophen. This dosage regimen of XARTEMIS XR was administered to 607 patients in two Phase 3 studies (one placebo-controlled and one open-label).

In a placebo-controlled post-bunionectomy acute pain trial, 329 patients were dosed with 15 mg oxycodone and 650 mg acetaminophen XARTEMIS XR or placebo orally every 12 hours, for approximately 48 hours (blinded period) [see Clinical Studies]. Table 1 lists the adverse reactions reported by ≥ 1% of XARTEMIS XR-treated patients and more frequently in XARTEMIS XRtreated patients compared with placebo.
