Xartemis XR Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Xartemis XR (oxycodone hydrochloride and acetaminophen) is a combination of an opioid (narcotic) pain reliever and the analgesic acetaminophen used to manage acute pain severe enough to require opioid treatment and for which alternative treatment options are inadequate. Common side effects include nausea, dizziness, headache, vomiting, constipation, and sleepiness.
The recommended dose of Xartemis XR is 2 tablets every 12 hours administered with or without food. Xartemis XR may interact with other CNS depressants (including sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and alcohol), skeletal muscle relaxants, monoamine oxidase inhibitors (MAOIs), certain cardiovascular drugs (including amiodarone and quinidine), antidepressants, CYP3A4 inhibitors, pentazocine, nalbuphine, butorphanol, and buprenorphine, and anticholinergics. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or planning to become pregnant before using Xartemis XR. Using this drug while pregnant or near delivery may cause withdrawal symptoms in your newborn. This drug passes into breast milk and may harm a nursing baby. Breastfeeding is not recommended while using Xartemis XR. Withdrawal symptoms may occur if you suddenly stop taking this medication.
Our Xartemis XR (oxycodone hydrochloride and acetaminophen) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
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 XR-treated patients compared with placebo.

The following adverse drug reactions not listed above occurred in ≥ 1% of XARTEMIS XR-treated patients in the pooled safety data from two Phase 3 studies (including a placebo-controlled and an open-label non-controlled safety study) where multiple-doses of XARTEMIS XR were administered every 12 hours for up to 42 days:
General disorders and administration site conditions: fatigue Investigations: hepatic enzyme increased
Psychiatric disorders: insomnia
Respiratory, thoracic and mediastinal disorders: cough
The following adverse drug reactions occurred in < 1% of XARTEMIS XR-treated patients in the pooled safety data from the two Phase 3 studies described above:
Cardiac disorders: palpitations
Eye and ear disorders: tinnitus, vision blurred
Gastrointestinal disorders: abdominal discomfort, abdominal pain, esophageal spasm
Immune system disorders: hypersensitivity
Investigations: alanine aminotransferase increased, aspartate aminotransferase increased, blood lactate dehydrogenase increased, blood pressure increased, gamma-glutamyltransferase increased, liver functional test abnormal
