Therapeutic Use:

Indications for OPANA ER:

Moderate-to-severe pain when the use of a continuous, around-the-clock opioid is required for an extended period of time. Not for use: as an as-needed (prn) analgesic, for pain that is mild or not expected to persist for an extended period of time, for acute pain, or for postoperative pain unless already receiving chronic opioid therapy prior to surgery or if the postoperative pain is expected to be moderate-to-severe and persist for an extended period of time.

Adult Dose for OPANA ER:

Individualize. Take on empty stomach. May give Opana as needed on an every 4–6 hrs schedule; Opana ER is given on a continuous basis every 12hrs. ≥18yrs: Opioid-naive: Opana: 5–20mg every 4–6 hrs as needed. Opana ER: Swallow whole; 5mg every 12 hrs, titrate by 5–10mg every 12 hours every 3–7 days; if breakthrough pain occurs: adjust dose or use a small-dose rescue medication (eg, immediate-release oxymorphone). Converting from Opana to Opana ER: Give half the total daily Opana dose as Opana ER every 12 hrs. Converting from parenteral oxymorphone, or other opioids to Opana or Opana ER: see full labeling. Mild hepatic impairment, renal impairment (CrCl <50mL/min), or elderly (≥65yrs): opioid-naive: initiate with 5mg dose; opioid-experience: initiate at 50% lower than normal starting dose and titrate slowly.
