Exposes patients and other users to the risk of opioid addiction/abuse/misuse, which may lead to overdose and death; assess risk prior to therapy and monitor all patients regularly for development of these behaviors or conditions. Serious, life-threatening, or fatal respiratory depression may occur; monitor especially during initiation or following a dose increase. Contraindicated for use as a PRN analgesic, in nonopioid tolerant patients, in acute pain, and in postoperative pain. Deaths due to fatal overdose have occurred from accidental exposure; strict adherence to handling/disposal instructions is of utmost importance to prevent accidental exposure. Prolonged use during pregnancy may result in neonatal opioid withdrawal syndrome. Concomitant use with all CYP3A4 inhibitors and discontinuation of a concomitantly administered CYP3A4 inducer may increase plasma concentrations and potentially cause fatal respiratory depression; monitor patients during concomitant therapy. Exposure of application site and surrounding area to direct external heat sources may increase absorption and result in fatal overdose and death; patients who develop fever or increased core body temperature due to strenuous exertion are at increased risk and may require dose adjustment.
Management of pain in opioid-tolerant patients severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.
Adults: Individualize dose based on prior analgesic treatment experience. D/C or taper all other extended-release (ER) and around-the-clock opioids when beginning therapy. Minimum Initial: 25mcg/hr for 72 hrs. Titrate: Wait at least 3 days after initial dose to increase dose for the 1st time. Titrate dose based on daily dose of supplemental opioid analgesics required on the 2nd or 3rd day of initial application. Evaluate for further titration after no less than two 3-day applications before increasing dose. Dosage increments may be based on the daily dose of supplementary opioids using the ratio of 45mg/24 hrs of oral morphine to a 12mcg/hr increase in fentanyl dose. May require q48h applications rather than q72h; an increase in dose should be evaluated before changing the interval. Maint: Continually reevaluate pain control, adverse reactions, and need for therapy. Refer to PI for dose conversion from PO/parenteral opioids to fentanyl patch, recommended initial dose based upon daily oral morphine dose, and discontinuation recommendations. Mild to Moderate Hepatic/Renal Impairment: Start with 1/2 of the usual dosage. Elderly: Start at lower end of the dosing range.
Pediatrics: ≥2 Yrs: Individualize dose based on prior analgesic treatment experience. D/C or taper all other ER and around-the-clock opioids when beginning therapy. Minimum Initial: 25mcg/hr for 72 hrs. Titrate: Wait at least 3 days after initial dose to increase dose for the 1st time. Titrate dose based on daily dose of supplemental opioid analgesics required on the 2nd or 3rd day of initial application. Evaluate for further titration after no less than two 3-day applications before increasing dose. Dosage increments may be based on the daily dose of supplementary opioids using the ratio of 45mg/24 hrs of oral morphine to a 12mcg/hr increase in fentanyl dose. May require q48h applications rather than q72h; an increase in dose should be evaluated before changing the interval. Maint: Continually reevaluate pain control, adverse reactions, and need for therapy.

Mild to Moderate Hepatic/Renal Impairment: Start with 1/2 of the usual dosage. Elderly: Start at lower end of the dosing range.
Transdermal route. Refer to PI for further details on proper application/handling and disposal instructions.
Patch: 12mcg/hr, 25mcg/hr, 50mcg/hr, 75mcg/hr, 100mcg/hr [5s]
Opioid-intolerant patients; management of acute/intermittent pain, or in patients who require opioid analgesia for a short period; management of postoperative pain, including use after outpatient/day surgeries (eg, tonsillectomies); management of mild pain; significant respiratory compromise, especially if adequate monitoring and resuscitative equipment are not readily available; acute or severe bronchial asthma; diagnosis or suspicion of paralytic ileus.
Should be prescribed only by healthcare professionals knowledgeable in the use of potent opioids for the management of chronic pain. Reserve for use in patients for whom alternative treatment options (eg, nonopioid analgesics, immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. Do not use as the 1st opioid. Risk of addiction is increased with personal/family history of substance abuse or mental illness. Prescribe smallest appropriate quantity. Closely monitor elderly, cachectic, or debilitated patients for respiratory depression. May decrease respiratory drive to the point of apnea in patients with chronic pulmonary disease; consider use of other nonopioid analgesic alternatives if possible. Avoid in patients who may be susceptible to the intracranial effects of CO2 retention. May obscure clinical course of head injury and may increase intracranial pressure (ICP); monitor patients with brain tumors. May cause severe hypotension, including orthostatic hypotension and syncope, in ambulatory patients; increased risk with reduced blood volume. May produce bradycardia. Avoid use with severe hepatic/renal impairment. May cause spasm of the sphincter of Oddi; monitor patients with biliary tract disease (eg, acute pancreatitis). May cause increases in serum amylase concentration. Tolerance and physical dependence may develop during chronic therapy. May impair mental/physical abilities. Significant absorption from the skin continues for ≥24 hrs after patch removal. Avoid abrupt discontinuation; use a gradual downward dose titration. Not for use in women during and immediately prior to labor.
Respiratory depression, N/V, constipation, diarrhea, headache, muscle spasms, malaise, palpitations, dizziness, insomnia, somnolence, fatigue, feeling cold, hyperhidrosis, anorexia.
See Boxed Warning. Monitor respiratory depression when given with other drugs that depress respiration. Concomitant use with CNS depressants (eg, other opioids, sedatives, alcohol) may cause respiratory depression, hypotension, profound sedation, coma, or death; closely monitor and reduce dose of 1 or both agents. Coadministration with CYP3A4 inducers may lead to lack of efficacy of fentanyl or development of withdrawal; monitor for signs of opioid withdrawal and consider dose adjustments until stable drug effects are achieved. Avoid concomitant use with MAOIs or within 14 days of stopping such treatment. Mixed agonist/antagonist (eg, pentazocine, nalbuphine, butorphanol) or partial agonist (buprenorphine) analgesics may reduce analgesic effect or may precipitate withdrawal symptoms; avoid concomitant use. Monitor for signs of urinary retention or reduced GI motility with anticholinergics or other medications with anticholinergic activity.
Category C, not for use in nursing.
Opioid analgesic; interacts predominantly with the opioid mu-receptor in the brain, spinal cord, and other tissues.
Absorption: Tmax=20-72 hrs. Transdermal administration of variable doses resulted in different parameters. Distribution: Vd=6L/kg; found in breast milk; crosses placenta. Metabolism: Liver via CYP3A4; oxidative N-dealkylation to norfentanyl. Elimination: (IV) Urine (75%, <10% unchanged), feces (9% primarily metabolites); T1/2=7 hrs (IV).
Assess for degree of opioid tolerance, type and severity of pain, risks for opioid abuse, addiction, or misuse, paralytic ileus, acute/severe bronchial asthma, history of hypersensitivity to drug or any component of patch, debilitation, seizures, biliary tract disease, any other conditions where treatment is contraindicated or cautioned, pregnancy/nursing status, and possible drug interactions.
Monitor for signs/symptoms of respiratory depression, bradycardia, worsening of biliary tract disease, increased ICP, increased serum amylase levels, increased body temperature/fever, abuse, misuse, addiction, tolerance/physical dependence, opioid withdrawal syndrome in neonates born to mothers on prolonged therapy during pregnancy, and other adverse reactions.
Inform that use of patch may result in addiction, abuse, and misuse, which may lead to overdose or death; instruct not to share with others and protect from theft, misuse, and from children. Inform of the risk of life-threatening respiratory depression; advise on how to recognize respiratory depression and to seek medical attention. Instruct to avoid accidental contact when holding or caring for children. Instruct to immediately take patch off if it dislodges and accidentally sticks to the skin of another person, wash exposed area with water, and seek medical attention. Advise to never change the dose/number of patches unless instructed. Advise how to safely taper medication and not to stop abruptly. Warn of the potential for temperature-dependent increases in drug release from patch; instruct to avoid strenuous exertion that may increase body temperature and avoid exposing application site and surrounding area to direct external heat sources. Counsel that medication may impair mental and/or physical ability; instruct patients to refrain from potentially hazardous tasks until therapy is established that they have not been adversely affected. Inform of pregnancy risks and advise women of childbearing potential who become/are planning to become pregnant to consult physician prior to initiating or continuing therapy. Advise to notify physician of all medications currently being taken and avoid using other CNS depressants and alcohol. Inform that severe constipation may develop. Instruct to refer to the instructions for use for proper disposal of patch.
