⊘Indications and dosages
➣ Breakthrough pain in opioid-tolerant patients with cancer
Adults: One 200-mcg lozenge (Actiq) dissolved in mouth over 15 minutes; additional unit may be given 15 minutes later. If patient needs more than 1 unit per episode (evaluated over several episodes), dosage may be increased; for optimal use or titration, don't exceed 4 units daily. For patient not being converted from Actiq, give 100 mcg (Fentora). For patient being converted from Actiq, follow dosing recommendations below for Fentora.
If breakthrough pain doesn't ease after 30 minutes, give another dose once, using same strength previously given. Administer maximum of two doses for any breakthrough episode. Wait at least 4 hours before giving Fentora for another breakthrough episode.
For patients receiving sublingual tablets (Abstral), initially 100 mcg. Individually titrate to a tolerable dose that provides adequate analgesia. Give no more than two doses per breakthrough pain episode. Wait at least 2 hours before treating another episode of breakthrough pain with Abstral. Limit consumption to treat four or fewer breakthrough pain episodes per day once a successful dose is found.
For patients receiving buccal soluble film (Onsolis), 200 mcg as initial starting dose; titrate using 200-mcg increments (up to a maximum of four 200-mcg films or a single 1,200-mcg film) to provide adequate analgesia without undue adverse effects. Maximum is one dose per episode, no more than four doses per day; separate by at least 2 hours.
For patients receiving sublingual spray (Subsys), initially 100 mcg. Individually titrate to a tolerable dose that provides adequate analgesia using a single dose per breakthrough pain episode. For each breakthrough pain episode treated, if pain isn't relieved after 30 minutes, patients may take only one additional dose of the same strength for that episode; patients should take a maximum of two doses of Subsys for any breakthrough pain episode. Patients must wait at least 4 hours before treating another episode of breakthrough pain. If necessary, increase dose to next highest strength (200 mcg). Subsequent titration steps are 400 mcg, 600 mcg, 800 mcg, 1,200 mcg, and 1,600 mcg. For maintenance, once dosage has been titrated to a level that provides adequate pain relief and tolerable adverse effects, patients should generally use only one dose of the appropriate strength per breakthrough pain episode.
For patients receiving nasal spray, initially 100 mcg (a single spray into one nostril or a single spray into each nostril). Individually titrate to an effective dose, from 100 mcg to 200 mcg to 400 mcg, up to a maximum of 800 mcg, that provides adequate analgesia with tolerable adverse effects. Maximum dose is a single spray into one nostril or single spray into each nostril per episode; no more than four doses per 24 hours. Wait at least 2 hours before treating another episode of breakthrough pain with Lazanda. During any episode, if adequate pain relief isn't achieved within 30 minutes, patients may use a rescue drug as directed by prescriber.
Patients must require and use around-the-clock opioids when taking Abstral, Actiq, Fentora, Lazanda, Onsolis, or Subsys.
➣ Management of chronic pain in patients requiring opioid analgesics
Adults: Initially, 25 mcg/hour (transdermal system); no more than 25 mcg/hour in patients who haven't been receiving opioids. To calculate dosage for patients already receiving opioids, assess 24-hour requirement for current opioid. Using equianalgesic table in prescribing information, convert to equivalent amount of morphine per 24 hours; then convert morphine dosage to appropriate dosage of transdermal fentanyl. During initial application, keep short-acting opioids on hand to treat breakthrough pain; morphine 10 mg I.M. or 60 mg P.O. q 4 hours (60 mg/24 hours I.M. or 360 mg/24 hours P.O.) is roughly equivalent to transdermal fentanyl 100 mcg/hour. For most patients, transdermal patch lasts 72 hours, but some require new patch q 48 hours.
➣ Short-term analgesia during anesthesia and immediate preoperative and postoperative periods
Adults: Individualized; 0.05 to 0.1 mg (Sublimaze) I.M. 30 to 60 minutes before surgery and as adjunct to general anesthesia; total dosage is 0.002 mg/kg. Maintenance dosage during surgery is 0.025 to 0.1 mg I.V. or I.M. Postoperatively, 0.05 to 0.1 mg I.M. to control pain, tachypnea, or emergence delirium; repeat in 1 to 2 hours if needed.
Children ages 2 to 12: Individualized; 2 to 3 mcg/kg (Sublimaze) I.V. depending on vital signs, or 5 to 15 mcg/kg (Fentanyl Oralet) transmucosally
➣ General anesthesia (with oxygen only)
Adults: Individualized; 0.05 to 0.1 mg/kg (Sublimaze) I.V. for high-dose therapy. Up to 0.12 mg/kg may be necessary.
➣ Adjunct to regional anesthesia
Adults: Individualized; 0.05 to 0.1 mg (Sublimaze) I.M. or slow I.V. over 1 to 2 minutes

• Don't open buccal tablet blister pack until ready to administer; don't push tablet through blister backing.
• Open buccal soluble film and spray packages immediately before use.
• Be aware that in some patients, dosages of both Fentora and maintenance (around-the-clock) opioid analgesic may need to be adjusted to provide ongoing relief of breakthrough pain. Generally, Fentora dosage should be increased if patient needs more than one dose per breakthrough pain episode for several consecutive episodes.
• Inject I.V. dose slowly over 3 to 5 minutes.
☞ Keep opioid antagonist (naloxone) and emergency equipment available when giving drug I.V.
• Administer sublingual tablets on floor of mouth directly under tongue and allow to completely dissolve.
• Prime nasal spray device before use as directed by manufacturer.
• For patients no longer requiring opioid therapy, consider discontinuing sublingual tablets or nasal spray along with gradual downward titration of other opioids to minimize possible withdrawal effects. For patients who continue to take long-term opioid therapy for persistent pain but no longer require treatment for breakthrough pain, sublingual tablets or nasal spray can usually be discontinued immediately.
• Be aware that drug isn't recommended for control of mild or intermittent pain.
• Be aware that fentanyl products are generally not interchangeable or substitutable on a mcg-per-mcg basis with other fentanyl products.

☞ Assess for muscle rigidity in patients receiving high doses; discuss need for neuromuscular blockers with prescriber. Patient receiving blocker will need ventilator.
• Monitor respiratory and cardiovascular function and urine output.
• With transdermal system, monitor patient's pain level often to determine if patch is effective for 72 hours or needs to be replaced after 48 hours. Know that drug level rises gradually for first 24 hours after patch is applied; supplemental analgesics may be needed then.
• If patient develops fever, assess for signs and symptoms of opioid toxicity, as more drug is absorbed at higher body temperatures.
• If adverse reactions to transdermal system occur, monitor patient for at least 12 hours after patch removal.
• Carefully monitor hematologic studies and hepatic enzyme levels.
☞ Caution patient to keep transmucosal (lozenge) form out of children's reach even though it is supplied in individually sealed, child-resistant pouch. One lozenge can be fatal to a child.
• Instruct patient to place lozenge between cheek and gum and suck on it for 15 minutes without chewing or swallowing.
• Teach patient proper technique for applying and disposing of transdermal patch.
• Tell patient that transdermal form is absorbed more rapidly if skin is warm from fever or hot environment. Instruct patient to avoid electric blankets, heating pads, heat lamps, hot tubs, and heated water beds and to promptly report fever or a move to a hot climate.
• Instruct patient not to open buccal tablet blister pack until ready to use. Teach patient to peel back blister backing to expose buccal tablet and not to push tablet through blister.
• Caution patient not to break, suck, chew, or swallow buccal tablet.
• Instruct patient to place buccal tablet between upper check and gum near rear molar until it dissolves, and to swallow remnants with a glass of water after 30 minutes.
• Instruct patient to use alternate sides of mouth when taking subsequent doses of buccal tablets.
• Instruct patient to open buccal soluble film or spray packages immediately before use.
• Instruct patient to rinse mouth with water to wet area for placement of buccal soluble film. Tell patient to place entire buccal soluble film near tip of a dry finger with pink side facing up and to place pink side of film against inside of cheek; then to press and hold film in place for 5 seconds, after which film should stay in place on its own. Tell patient that liquids may be consumed after 5 minutes. Instruct patient that film will dissolve in 15 to 30 minutes and not to chew, swallow, or manipulate film with tongue or fingers or eat food until film has dissolved. Advise patient or caregiver to properly dispose of Onsolis film because drug can be fatal to children.
• Tell patient to place sublingual tablets on floor of mouth directly under tongue immediately after removal from blister unit. Tell patient not to chew, suck, or swallow tablets and allow tablets to completely dissolve in the sublingual cavity. Instruct patient not to eat or drink anything until tablets have completely dissolved. Advise patient who has a dry mouth that water may be used to moisten buccal mucosa before taking tablets.
• Instruct patient to carefully spray contents of sublingual spray unit into mouth underneath tongue. Tell patient or caregiver to dispose of used unit-dose systems immediately after use. Also tell patient to dispose of any unneeded unit-dose systems remaining from a prescription as soon as they are no longer needed. Consumed units represent a special risk because they are no longer protected by the child-resistant blister package, yet may contain enough drug to be fatal to children.
• Instruct patient on proper use of nasal spray and to press down firmly on finger grips until a "click" is heard and number in counting window advances by one. Tell patient that the fine mist spray isn't always felt on nasal mucosal membrane and to rely on the audible click and advancement of dose counter to confirm that a spray has been administered. Advise patient or caregiver that nasal spray contains an amount of drug that could be fatal to children, to individuals for whom it isn't prescribed, and to those who aren't opioid-tolerant.
• Tell patient to avoid grapefruit and grapefruit juice while taking drug.
• Advise patient not to breastfeed while taking drug.
• Caution patient to avoid driving and other hazardous activities until drug's effects on concentration and alertness are known.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, foods, herbs, and behaviors mentioned above.

Drug-Drug interactionAvoid use in patients who have received MAO inhibitors within the previous 14 days (may produce unpredictable, potentially fatal reactions).Concomitant use of CYP3A4 inhibitors including ritonavir, ketoconazole, itraconazole, clarithromycin, nelfinavir, nefazodone, amiodarone, diltiazem, aprepitant, fluconazole, fosamprenavir, verapamil, and erythromycin may result in ↑ plasma levels and ↑ risk of CNS and respiratory depression.Levels and effectiveness may be ↓ by drugs that induce the CYP3A4 enzyme.↑ CNS and respiratory depression with other CNS depressants, including alcohol, antihistamines, antidepressants, sedative/hypnotics, and other opioids.Concomitant use of kava-kava, valerian, or chamomile can ↑ CNS depression.Grapefruit juice is a moderate inhibitor of the CYP3A4 enzyme system; concurrent use may ↑ blood levels and the risk of respiratory and CNS depression. Careful monitoring and dose adjustment is recommended.
Availability (generic available)
- Assess type, location, and intensity of pain before and 24 hr after application and periodically during therapy. Monitor pain frequently during initiation of therapy and dose changes to assess need for supplementary analgesics for breakthrough pain.
- Assess BP, pulse, and respirations before and periodically during administration. If respiratory rate is <10/min, assess level of sedation. Physical stimulation may be sufficient to prevent significant hypoventilation. Dose may need to be decreased by 25–50%. Initial drowsiness will diminish with continued use.
- Prolonged use may lead to physical and psychological dependence and tolerance. This should not prevent patient from receiving adequate analgesia. Most patients who receive opioid analgesics for pain do not develop psychological dependence.
- Progressively higher doses may be required to relieve pain with long-term therapy. It may take up to 6 days after increasing doses to reach equilibrium, so patients should wear higher dose through 2 applications before increasing dose again.
- Assess bowel function routinely. Prevent constipation with increased intake of fluids and bulk, and laxatives to minimize constipating effects. Administer stimulant laxatives routinely if opioid use exceeds 2–3 days, unless contraindicated.
- Lab Test Considerations: May ↑ plasma amylase and lipase levels. If an opioid antagonist is required to reverse respiratory depression or coma, naloxone is the antidote. Dilute the 0.4-mg ampule of naloxone in 10 mL of 0.9% NaCl and administer 0.5 mL (0.02 mg) by direct IV push every 2 min. For patients weighing <40 kg, dilute 0.1 mg of naloxone in 10 mL of 0.9% NaCl for a concentration of 10 mcg/mL and administer 0.5 mcg/kg every 2 min. Titrate dose to avoid withdrawal, seizures, and severe pain. Monitor patient closely; dose may need to be repeated or may need to be administered as an infusion because of long duration of action despite removal of patch.
Potential Nursing DiagnosesChronic pain (Indications)
Risk for injury (Side Effects)
- Do not confuse fentanyl with sufentanil.
- high alert: Accidental overdose of opioid analgesics has resulted in fatalities. Before administering, confirm patient is opioid tolerant and clarify ambiguous orders; have second practitioner independently check original order and dose calculations.
- 12-mcg patch delivers 12.5 mcg/hr of fentanyl. Use supplemental doses of short-acting opioid analgesics to manage pain until relief is obtained with the transdermal system. Patients may continue to require supplemental opioids for breakthrough pain. If >100 mcg/hr is required, use multiple transdermal systems.
- Titrate dose based on patient’s report of pain until adequate analgesia (50% reduction in patient’s pain rating on numerical or visual analogue scale or patient reports satisfactory relief) is attained. Determine dose by calculating the previous 24-hr analgesic requirement and converting to the equianalgesic morphine dose using. The conversion ratio from morphine to transdermal fentanyl is conservative; 50% of patients may require a dose increase after initial application. Increase after 3 days based on required daily doses of supplemental analgesics. Increases should be based on ratio of 45 mg/24 hr of oral morphine to 12.5 mcg/hr increase in transdermal fentanyl dose.
- Coadministration with nonopioid analgesics may have additive analgesic effects and permit lower opioid doses.
- To convert to another opioid analgesic, remove transdermal fentanyl system and begin treatment with half the equianalgesic dose of the new analgesic in 12–18 hr.
- Medication should be discontinued gradually after long-term use to prevent withdrawal symptoms.
- Transdermal: Apply system to flat, nonirritated, and nonirradiated site such as chest, back, flank, or upper arm. If skin preparation is necessary, use clear water and clip, do not shave, hair. Allow skin to dry completely before application. Apply immediately after removing from package. Do not alter the system (i.e., cut) in any way before application. Remove liner from adhesive layer and press firmly in place with palm of hand for 30 sec, especially around the edges, to make sure contact is complete. Remove used system and fold so that adhesive edges are together. Flush system down toilet immediately on removal or follow the institutional policy. Apply new system to a different site.
- Instruct patient in how and when to ask for and take pain medication.
- Instruct patient in correct method for application and disposal of transdermal system. Fatalities have occurred from children having access to improperly discarded patches. May be worn while bathing, showering, or swimming.
- Advise patient to avoid grapefruit juice during therapy.
- May cause drowsiness or dizziness. Caution patient to call for assistance when ambulating or smoking and to avoid driving or other activities requiring alertness until response to medication is known.
- Advise patient to change positions slowly to minimize dizziness.
- Caution patient to avoid concurrent use of alcohol or other CNS depressants with this medication.
- Advise patient that fever, electric blankets, heating pads, saunas, hot tubs, and heated water beds increase the release of fentanyl from the patch.
- Advise patient that good oral hygiene, frequent mouth rinses, and sugarless gum or candy may decrease dry mouth.
- Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications.
- Instruct female patient to notify health care professional if pregnancy is planned or suspected or if breast feeding.
- Advise patient referred for MRI test to discuss patch with referring health care professional and MRI facility to determine if removal of patch is necessary prior to test and for directions for replacing patch.
- Decrease in severity of pain without a significant alteration in level of consciousness, respiratory status, or BP.
