Usual Adult Dose for Pain

FENTANYL TRANSDERMAL PATCH:
Initial dose: 25 mcg/hour patch (unless opioid tolerance) every 72 hours.

FENTANYL TRANSMUCOSAL:
Initial dose: 200 mcg, place in mouth (between cheek and lower gum) and suck over 15 minutes (do not chew or swallow).

FENTANYL IONTOPHORETIC TRANSDERMAL SYSTEM:
Patients should be titrated to comfort before initiating the fentanyl iontophoretic transdermal system. Fentanyl iontophoretic transdermal system should be applied to intact, nonirritated, nonirradiated skin on the chest or upper outer arm.
Patients must have access to supplemental analgesia during treatment with the fentanyl iontophoretic transdermal system. Fentanyl iontophoretic transdermal system provides a 40 mcg dose of fentanyl per activation on-demand. It is important to instruct patients how to operate fentanyl iontophoretic transdermal system to self-administer doses of fentanyl as needed to manage their acute, short-term, postoperative pain. Only the patient should administer doses from fentanyl iontophoretic transdermal system. Each on-demand dose is delivered over a 10-minute period. To initiate administration of a fentanyl dose, the patient must press the button firmly twice within 3 seconds. An audible tone (beep) indicates the start of delivery of each dose; the red light remains on throughout the 10 minute dosing period.
Patients on chronic opioid therapy or with a history of opioid abuse may require higher analgesic doses in the postoperative period than are available from fentanyl iontophoretic transdermal system. Therefore, these patients should be evaluated frequently to ensure they are receiving adequate analgesia.
A maximum of six 40 mcg doses per hour can be administered by fentanyl iontophoretic transdermal system. The maximum amount of fentanyl that can be administered from a single fentanyl iontophoretic transdermal system over 24 hours is 3.2 mg (eighty 40 mcg doses). Each fentanyl iontophoretic transdermal system operates for 24 hours or until eighty doses have been administered, whichever occurs first. Up to three consecutive fentanyl iontophoretic transdermal systems may be used sequentially, each applied to a different skin site for a maximum of 72 hours of therapy for acute, short-term, postoperative pain.

FENTANYL BUCCAL TABLET:
Initial Dose: 100 mcg.
Dose Titration: Patients should be titrated to a dose of fentanyl buccal tablet that provides adequate analgesia with tolerable side effects.
For patients switching from oral transmucosal fentanyl citrate to fentanyl buccal tablet, the starting dose of fentanyl buccal tablet should be as follows. An oral transmucosal fentanyl citrate dose of 200 mcg or 400 mcg converts to an initial fentanyl buccal tablet dose of 100 mcg. An oral transmucosal fentanyl citrate dose of 600 or 800 mcg converts to an initial fentanyl buccal tablet dose of 200 mcg. And, an oral transmucosal fentanyl citrate dose of 1200 mcg or 1600 mcg converts to an initial fentanyl buccal tablet dose of 400 mcg.
Redosing Patients Within a Single Episode: Dosing may be repeated once during a single episode of breakthrough pain if pain is not adequately relieved by one fentanyl buccal tablet dose. Redosing may occur 30 minutes after the start of administration of fentanyl buccal tablet and the same dosage strength should be used.

FENTANYL BUCCAL SOLUBLE FILM:
For use only for the management of breakthrough pain in patients with cancer who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain:
The goal of dose titration is to find the individual patient's effective and tolerable dose. The dose of fentanyl buccal soluble film is not predicted from the daily maintenance dose of opioid used to manage the persistent cancer pain and must be determined by dose titration.
Individually titrate fentanyl buccal soluble film to a dose that provides adequate analgesia with tolerable side effects.
Initial dose: All patients must begin treatment using one 200 mcg fentanyl buccal soluble film. Due to differences in pharmacokinetic properties and individual variability, patients switching from another oral transmucosal fentanyl product must be started on no greater than 200 mcg of fentanyl buccal soluble film. When prescribing, do not switch patients on a mcg per mcg basis from any other oral transmucosal fentanyl product to fentanyl buccal soluble film as fentanyl buccal soluble film is not equivalent on a mcg per mcg basis with any other fentanyl product. Fentanyl buccal soluble film is not a generic version of any other oral transmucosal fentanyl product.
Following the initial dose, closely follow patients and change the dosage level until the patient reaches a dose that provides adequate analgesia. If adequate pain relief is not achieved after one 200 mcg fentanyl buccal soluble film, titrate using multiples of the 200 mcg fentanyl buccal soluble film (for doses of 400, 600, or 800 mcg). Increase the dose by 200 mcg in each subsequent episode until the patient reaches a dose that provides adequate analgesia with tolerable side effects. Do not use more than four of the 200 mcg fentanyl buccal soluble film simultaneously. When multiple 200 mcg fentanyl buccal soluble films are used, they should not be placed on top of each other and may be placed on both sides of the mouth.
If adequate pain relief is not achieved after 800 mcg fentanyl buccal soluble film (i.e., four 200 mcg fentanyl buccal soluble films), and the patient has tolerated the 800 mcg dose, treat the next episode by using one 1200 mcg fentanyl buccal soluble film. Doses above 1200 mcg fentanyl buccal soluble film should not be used.
The patient should then get a prescription for fentanyl buccal soluble film of the dose determined by titration (i.e., 200, 400, 600, 800, or 1200 mcg) to treat subsequent episodes.
Single doses should be separated by at least 2 hours. Fentanyl buccal soluble film should only be used once per breakthrough cancer pain episode, i.e., fentanyl buccal soluble film should not be redosed within an episode.
During any episode of breakthrough cancer pain, if adequate pain relief is not achieved from use of fentanyl buccal soluble film, the patient may use a rescue medication (after 30 minutes) as directed by their healthcare provider.
During maintenance treatment, if the prescribed dose no longer adequately manages the breakthrough cancer pain episode for several consecutive episodes, increase the dose of fentanyl buccal soluble film. Once a successful dose has been found, each episode is treated with a single film. Fentanyl buccal soluble film should be limited to four or fewer doses per day. Consider increasing the dose of the around-the-clock opioid medicine used for persistent cancer pain in patients experiencing more than four breakthrough cancer pain episodes daily.
The tongue should be used to wet the inside of the cheek or rinse the mouth with water to wet the area for placement of fentanyl buccal soluble film. The fentanyl buccal soluble film package should be opened immediately prior to product use. Place the entire fentanyl buccal soluble film near the tip of a dry finger with the pink side facing up and hold in place. Place the pink side of the fentanyl buccal soluble film against the inside of the cheek. Press and hold the fentanyl buccal soluble film in place for five seconds. The fentanyl buccal soluble film should stay in place on its own after this period. Liquids may be consumed after five minutes. Fentanyl buccal soluble film, if chewed and swallowed, might result in lower peak concentrations and lower bioavailability than when used as directed.
The fentanyl buccal soluble film should not be cut or torn prior to use. The fentanyl buccal soluble film will dissolve within 15 to 30 minutes after application. The film should not be manipulated with the tongue or finger(s). Eating food should be avoided until the film has dissolved.

FENTANYL SUBLINGUAL TABLETS:
For use only for the management of breakthrough pain in patients with cancer who are 18 years of age and older and who are already receiving and are tolerant to opioid therapy for their underlying persistent cancer pain. Patients considered opioid tolerant are those who are taking pain relief medication around-the-clock of at least 60 mg of oral morphine daily, or at least 25 mcg of transdermal fentanyl/hour, or at least 30 mg of oral oxycodone daily, or at least 8 mg of oral hydromorphone daily or at least 25 mg oral oxymorphone daily, or an equal dose of another opioid medication daily for 7 days or more.
The goal of dose titration is to find the effective and tolerable dose for the individual patient. The dose of fentanyl sublingual is not predicted from the daily maintenance dose of opioid used to manage the persistent cancer pain and must be determined by dose titration.
Fentanyl sublingual tablets should be placed on the floor of the mouth directly under the tongue immediately after removal from the packaging. The patient should be instructed not to chew, suck, or swallow the sublingual tablet. Patients should not eat or drink anything until the tablet is completely dissolved. Water may be used to moisten the buccal mucosa before taking fentanyl sublingual in patients who have a dry mouth.
Initial dose: All patients must begin treatment with a single 100 mcg sublingual tablet. Due to differences in pharmacokinetic properties and individual variability, patients switching from another fentanyl product must be started on the 100 mcg sublingual dose. Patients should not be switched on a mcg per mcg basis from any other fentanyl product to fentanyl sublingual as fentanyl sublingual is not equivalent on a mcg per mcg basis with any other fentanyl product. Fentanyl sublingual is not a generic version of any other fentanyl product. Following the initial dose, patients should be followed closely and the dosage level adjusted until the patient reaches a dose that provides adequate analgesia. If adequate analgesia is obtained within 30 minutes of administration of the 100 mcg tablet, continue to treat subsequent episodes of breakthrough pain with this dose. If adequate pain relief is not achieved after one 100 mcg tablet, the patient may take a second dose (after 30 minutes). No more than 2 doses may be used to treat one episode of breakthrough pain. Patients must wait at least 2 hours after the last dose to treat another episode of breakthrough pain.
Titration: If adequate pain relief is not achieved after the first 100 mcg dose, the dose should be increased in a stepwise manner over consecutive breakthrough pain episodes until adequate analgesia with tolerable side effects is achieved. The dose should be increased by 100 mcg multiples up to 400 mcg if needed. If adequate analgesia is not obtained with a 400 mcg dose, increase to 600 mcg. If adequate analgesia is not obtained with a 600 mcg dose, increase to 800 mcg. During titration, patients can be instructed to use multiples of 100 mcg tablets and/or 200 mcg tablets for any single dose. Patients should not use more than 4 tablets at one time. If adequate analgesia is not obtained 30 minutes after use, the patient may repeat the same dose. No more than two doses of may be used to treat an episode of breakthrough pain. Rescue medication as directed by the healthcare provider may be used if adequate analgesia is not achieved.
The efficacy and safety of doses higher than 800 mcg have not been evaluated in clinical studies.
Maintenance: Once an appropriate dose for pain management has been established, patients should be instructed to use only one tablet of the appropriate strength per dose. Patients should be maintained on this dose. If adequate analgesia is not obtained, the patient may use a second dose (after 30 minutes) as directed by their health care provider. No more than two doses may be used to treat an episode of breakthrough pain. Patients must wait at least 2 hours before treating another episode of breakthrough pain.
Dose readjustment: If the response (analgesia or adverse reactions) to the titrated dose markedly changes, an adjustment of dose may be necessary to ensure that an appropriate dose is maintained.
If more than four episodes of breakthrough pain are experienced daily, the dose of the long-acting opioid used for persistent underlying cancer pain should be reevaluated. If the long-acting opioid or dose of long-acting opioid is changed, the fentanyl sublingual dose should be retitrated as necessary to ensure the patient is on an appropriate dose.
The use of fentanyl sublingual should be limited to treat four or fewer episodes of breakthrough pain per day.
It is important that any dose retitration is monitored carefully by a healthcare professional.
Discontinuation: Patients no longer requiring opioid therapy may discontinue fentanyl sublingual along with a gradual downward titration of other opioids to minimize possible withdrawal effects. Patients who continue to take chronic opioid therapy for chronic pain but no longer need treatment for breakthrough pain may discontinue fentanyl sublingual immediately.

FENTANYL NASAL SPRAY:
For use only for the management of breakthrough pain in patients with cancer who are 18 years of age and older and who are already receiving and are tolerant to opioid therapy for their underlying persistent cancer pain.
Fentanyl nasal spray should be titrated to a dose that provides adequate analgesia with tolerable side effects.
Initial dose: Treatment of all patients (including those switching from another fentanyl product) should be initiated with 1 spray into 1 nostril.
Maintenance dose: If adequate analgesia is achieved within 30 minutes of administration of 1 spray in 1 nostril, subsequent episodes of breakthrough pain may be treated with this dose. If adequate analgesia is not achieved with the first dose, the dose should be escalated in a step wise manner over consecutive episodes of breakthrough pain until adequate analgesia with tolerable side effects is achieved.
Titration: Patients must wait at least 2 hours between doses:
Step 1: 1 spray (100 mcg per spray) into 1 nostril (100 mcg)
Step 2: 1 spray (100 mcg per spray) into each nostril (200 mcg)
Step 3: 1 spray (400 mcg per spray) into 1 nostril (400 mcg)
Step 4: 1 spray (400 mcg per spray) into each nostril (800 mcg)
Maximum dose: 800 mcg per episode of breakthrough pain no more often than every 2 hours and no more than 4 doses per day.
During any episode of breakthrough cancer pain, if there is inadequate pain relief after 30 minutes following fentanyl nasal spray dosing or if a separate episode of breakthrough cancer pain occurs before the next dose is permitted (i.e., within 2 hours), the healthcare provider should be prepared to offer the patient another medication for rescue.
There are no clinical data to support the use of a combination of dose strengths to treat an episode.

FENTANYL SUBLINGUAL SPRAY:
For use only for the management of breakthrough pain in patients with cancer who are 18 years of age and older and who are already receiving and are tolerant to opioid therapy for their underlying persistent cancer pain.
Fentanyl sublingual spray should be titrated to a dose that provides adequate analgesia with tolerable side effects. Patients should not be switched on a mcg per mcg basis to fentanyl sublingual spray from any other oral transmucosal fentanyl product. Fentanyl products are not equivalent on a mcg per mcg basis.
Initial dose: 100 mcg is always used as the initial dose
Titration: After the initial 100 mcg dose, patients should be assessed and the dose changed until the patient reaches a dose that provides adequate analgesia using a single dose per breakthrough cancer pain episode with tolerable side effects. For each breakthrough pain episode treated, if no relief is achieved after 30 minutes, patients may take only one additional dose of the same strength for that episode. (Maximum of 2 doses for any breakthrough pain episode). After the maximum 2 doses are taken, the patient must wait 4 hours before treating another episode of breakthrough pain. Generally, the dose should only be increased when a single administration of the current dose fails to adequately treat the breakthrough pain episode for several consecutive episodes. Subsequent titration steps are 400, 600, 800, 1200, and 1600 mcg. Patients should have only one strength available at any time. If the patient experiences greater than 4 breakthrough pain episodes per day, the dose of the maintenance (around-the-clock) opioid used for persistent pain should be reevaluated.

Usual Pediatric Dose for Anesthesia

Doses should be titrated to appropriate effects; wide range of doses exist, dependent upon desired degree of analgesia/anesthesia, clinical environment, patient's status, and presence of opioid tolerance.

Neonates: Analgesia: International Evidence-Based Group for Neonatal Pain recommendations:
Intermittent doses: Slow IV push: 0.5 to 3 mcg/kg/dose
---Continuous IV infusion: 0.5 to 2 mcg/kg/hour
---Sedation/analgesia: Slow IV push: 1 to 4 mcg/kg/dose; may repeat every 2 to 4 hours
---Continuous sedation/analgesia: Initial IV bolus: 1 to 2 mcg/kg, then 0.5 to 1 mcg/kg/hour; titrate upward
---Mean required dose: Neonates with gestational age less than 34 weeks: 0.64 mcg/kg/hour; neonates with gestational age greater than or equal to 34 weeks: 0.75 mcg/kg/hour

Older Infants and Children 1 to 12 years:
---Sedation for minor procedures/analgesia: IM or IV: 1 to 2 mcg/kg/dose; may repeat at 30 to 60 minute intervals. Note: Children 18 to 36 months of age may require 2 to 3 mcg/kg/dose.
--- Intranasal: Children greater than or equal to 10 kg: 1.5 mcg/kg once (maximum: 100 mcg/dose); reported range: 1 to 2 mcg/kg; some studies allowed for additional incremental doses of 0.5 mcg/kg to be administered every 5 minutes, not to exceed a total dose of 3 mcg/kg depending on pain type and severity.
---Continuous sedation/analgesia: Initial IV bolus: 1 to 2 mcg/kg then 1 mcg/kg/hour; titrate upward; usual: 1 to 3 mcg/kg/hour; some require 5 mcg/kg/hour
---Moderate to severe chronic pain: Transdermal patch: Opioid-tolerant children greater than or equal to 2 years receiving at least 60 mg oral morphine equivalents per day: Initial: 25 mcg/hour system or higher, based on conversion to fentanyl equivalents and administration of equianalgesic dosage (see package insert for further information); use short-acting analgesics for first 24 hours with supplemental PRN doses thereafter (for breakthrough pain); dose may be increased after 3 days, based on the daily dose of supplementary PRN opioids required; use the ratio of 45 mg of oral morphine equivalents per day to a 12.5 mcg/hour increase in transdermal patch dosage; change patch every 72 hours; Note: Dosing intervals less than every 72 hours are not recommended for children and adolescents. Initiation of the transdermal patch in children taking less than 60 mg of oral morphine equivalents per day has not been studied in controlled clinical trials; in open-label trials, children 2 to 18 years of age who were receiving at least 45 mg of oral morphine equivalents per day were started with an initial transdermal dose of 25 mcg/hour (or higher, depending upon equianalgesic dose of opioid received).

Children greater than or equal to 5 years and less than 50 kg:
Patient-controlled analgesia (PCA): IV: Opioid-naive: Note: PCA has been used in children as young as 5 years of age; however, clinicians need to assess children 5 to 8 years of age to determine if they are able to use the PCA device correctly. All patients should receive an initial loading dose of an analgesic (to attain adequate control of pain) before starting PCA for maintenance. Adjust doses, lockouts, and limits based on required loading dose, age, state of health, and presence of opioid tolerance. Use lower end of dosing range for opioid-naive. Assess patient and pain control at regular intervals and adjust settings if needed.

Usual concentration: Determined by weight; some clinicians use the following:
---Children less than 12 kg: 10 mcg/mL
---Children 12 to 30 kg: 25 mcg/mL
---Children greater than 30 kg: 50 mcg/mL
---Demand dose: Usual initial: 0.5 to 1 mcg/kg/dose; usual range: 0.5 to 1 mcg/kg/dose
---Lockout: Usual initial: 5 doses/hour
---Lockout interval: Range: 6 to 8 minutes
---Usual basal rate: 0 to 0.5 mcg/kg/hour

Children greater than 12 years to adult:
Sedation for minor procedures/analgesia: IV: 0.5 to 1 mcg/kg/dose; may repeat after 30 to 60 minutes; or 25 to 50 mcg, repeat full dose in 5 minutes if needed, may repeat 4 to 5 times with 25 mcg at 5 minute intervals if needed. Note: Higher doses are used for major procedures.

Continuous sedation/analgesia:
---Less than 50 kg: Initial IV bolus: 1 to 2 mcg/kg; continuous infusion rate: 1 to 2 mcg/kg/hour
---Greater than 50 kg: Initial IV bolus: 1 to 2 mcg/kg or 25 to 100 mcg/dose; continuous infusion rate: 1 to 2 mcg/kg/hour or 25 to 200 mcg/hour

Patient-controlled analgesia (PCA): IV: Children greater than 50 kg, Adolescents greater than 50 kg, and Adults: Note: All patients should receive an initial loading dose of an analgesic (to attain adequate control of pain) before starting PCA for maintenance. Adjust doses, lockouts, and limits based on required loading dose, age, state of health, and presence of opioid tolerance. Use lower end of dosing range for opioid-naive. Assess patient and pain control at regular intervals and adjust settings if needed:

---Usual concentration: 50 mcg/mL
---Demand dose: Usual initial: 20 mcg; usual range: 10 to 50 mcg
---Lockout interval: Usual initial: 6 minutes; usual range: 5 to 8 minutes
---Usual basal rate: less than or equal to 50 mcg/hour

Preoperative sedation, adjunct to regional anesthesia, postoperative pain: IM, IV: 25 to 100 mcg/dose

Adjunct to general anesthesia: Slow IV:
---Low dose: 0.5 to 2 mcg/kg/dose depending on the indication
---Moderate dose: Initial: 2 to 20 mcg/kg/dose; Maintenance (bolus or infusion): 1 to 2 mcg/kg/hour. Discontinuing fentanyl infusion 30 to 60 minutes prior to the end of surgery will usually allow adequate ventilation upon emergence from anesthesia. For "fast-tracking" and early extubation following major surgery, total fentanyl doses are limited to 10 to 15 mcg/kg.
---High dose: 20 to 50 mcg/kg/dose; Note: High dose fentanyl as an adjunct to general anesthesia is rarely used, but is still described in the manufacturer label.

General anesthesia without additional anesthetic agents: IV: 50 to 100 mcg/kg with oxygen and skeletal muscle relaxant

Moderate to severe chronic pain: Transdermal patch: Opioid tolerant patients receiving at least 60 mg oral morphine equivalents per day: Initial: 25 mcg/hour system or higher, based on conversion to fentanyl equivalents and administration of equianalgesic dosage (see package insert for further information); use short-acting analgesics for first 24 hours with supplemental PRN doses thereafter (for breakthrough pain); dose may be increased after 3 days based on the daily dose of supplementary PRN opioids required; use the ratio of 45 mg of oral morphine equivalents per day to a 12.5 mcg/hour increase in transdermal patch dosage; transdermal patch is usually administered every 72 hours but select adult patients may require every 48-hour administration; dosage increase administered every 72 hours should be tried before 48-hour schedule is used.

Adolescents greater than or equal to 16 years to adult: Breakthrough cancer pain: Transmucosal lozenge: Opioid-tolerant patients: Titrate dose to provide adequate analgesia: Initial: 200 mcg; may repeat dose only once, 15 minutes after completion of first dose if needed. Do not exceed a maximum of 2 doses per each breakthrough cancer pain episode; patient must wait at least 4 hours before treating another episode. Titrate dose up to next higher strength if treatment of several consecutive breakthrough episodes requires more than 1 lozenge per episode; evaluate each new dose over several breakthrough cancer pain episodes (generally 1 to 2 days) to determine proper dose of analgesia with acceptable side effects. Once the dose has been determined, consumption should be limited to less than or equal to 4 units/day. Reevaluate maintenance (around-the-clock) opioid dose if patient requires more than 4 units/day. If signs of excessive opioid effects occur before a dose is complete, the unit should be removed from the mouth immediately, and subsequent doses decreased.

Preoperative sedation, adjunct to regional anesthesia, postoperative pain: IM, IV: 25 to 100 mcg/dose

Adjunct to general anesthesia: Slow IV:
---Low dose: 0.5 to 2 mcg/kg/dose depending on the indication
---Moderate dose: Initial: 2 to 20 mcg/kg/dose; Maintenance (bolus or infusion): 1 to 2 mcg/kg/hour. Discontinuing fentanyl infusion 30 to 60 minutes prior to the end of surgery will usually allow adequate ventilation upon emergence from anesthesia. For "fast-tracking" and early extubation following major surgery, total fentanyl doses are limited to 10 to 15 mcg/kg.
---High dose: 20 to 50 mcg/kg/dose; Note: High dose fentanyl as an adjunct to general anesthesia is rarely used, but is still described in the manufacturer label.

General anesthesia without additional anesthetic agents: IV: 50 to 100 mcg/kg with oxygen and skeletal muscle relaxant

Moderate to severe chronic pain: Transdermal patch: Opioid tolerant patients receiving at least 60 mg oral morphine equivalents per day: Initial: 25 mcg/hour system or higher, based on conversion to fentanyl equivalents and administration of equianalgesic dosage (see package insert for further information); use short-acting analgesics for first 24 hours with supplemental PRN doses thereafter (for breakthrough pain); dose may be increased after 3 days based on the daily dose of supplementary PRN opioids required; use the ratio of 45 mg of oral morphine equivalents per day to a 12.5 mcg/hour increase in transdermal patch dosage; transdermal patch is usually administered every 72 hours but select adult patients may require every 48-hour administration; dosage increase administered every 72 hours should be tried before 48-hour schedule is used.

Adolescents greater than or equal to 16 years to adult: Breakthrough cancer pain: Transmucosal lozenge: Opioid-tolerant patients: Titrate dose to provide adequate analgesia: Initial: 200 mcg; may repeat dose only once, 15 minutes after completion of first dose if needed. Do not exceed a maximum of 2 doses per each breakthrough cancer pain episode; patient must wait at least 4 hours before treating another episode. Titrate dose up to next higher strength if treatment of several consecutive breakthrough episodes requires more than 1 lozenge per episode; evaluate each new dose over several breakthrough cancer pain episodes (generally 1 to 2 days) to determine proper dose of analgesia with acceptable side effects. Once the dose has been determined, consumption should be limited to less than or equal to 4 units/day. Reevaluate maintenance (around-the-clock) opioid dose if patient requires more than 4 units/day. If signs of excessive opioid effects occur before a dose is complete, the unit should be removed from the mouth immediately, and subsequent doses decreased.

Usual Pediatric Dose for Sedation

Doses should be titrated to appropriate effects; wide range of doses exist, dependent upon desired degree of analgesia/anesthesia, clinical environment, patient's status, and presence of opioid tolerance.

Neonates: Analgesia: International Evidence-Based Group for Neonatal Pain recommendations:
Intermittent doses: Slow IV push: 0.5 to 3 mcg/kg/dose
---Continuous IV infusion: 0.5 to 2 mcg/kg/hour
---Sedation/analgesia: Slow IV push: 1 to 4 mcg/kg/dose; may repeat every 2 to 4 hours
---Continuous sedation/analgesia: Initial IV bolus: 1 to 2 mcg/kg, then 0.5 to 1 mcg/kg/hour; titrate upward
---Mean required dose: Neonates with gestational age less than 34 weeks: 0.64 mcg/kg/hour; neonates with gestational age greater than or equal to 34 weeks: 0.75 mcg/kg/hour
---Continuous sedation/analgesia during extracorporeal membrane oxygenation (ECMO): Initial IV bolus: 5 to 10 mcg/kg slow IV push over 10 minutes, then 1 to 5 mcg/kg/hour; titrate upward; tolerance may develop; higher doses (up to 20 mcg/kg/hour) may be needed by day 6 of ECMO.

Younger infants:
---Sedation/analgesia: Slow IV push: 1 to 4 mcg/kg/dose; may repeat every 2 to 4 hours
---Continuous sedation/analgesia: Initial IV bolus: 1 to 2 mcg/kg, then 0.5 to 1 mcg/kg/hour; titrate upward
---Continuous sedation/analgesia during extracorporeal membrane oxygenation ECMO: Initial IV bolus: 5 to 10 mcg/kg slow IV push over 10 minutes, then 1 to 5 mcg/kg/hour; titrate upward; tolerance may develop; higher doses (up to 20 mcg/kg/hour) may be needed by day 6 of ECMO.

Older Infants and Children 1 to 12 years:
---Sedation for minor procedures/analgesia: IM or IV: 1 to 2 mcg/kg/dose; may repeat at 30 to 60 minute intervals. Note: Children 18 to 36 months of age may require 2 to 3 mcg/kg/dose.
--- Intranasal: Children greater than or equal to 10 kg: 1.5 mcg/kg once (maximum: 100 mcg/dose); reported range: 1 to 2 mcg/kg; some studies allowed for additional incremental doses of 0.5 mcg/kg to be administered every 5 minutes, not to exceed a total dose of 3 mcg/kg depending on pain type and severity.
---Continuous sedation/analgesia: Initial IV bolus: 1 to 2 mcg/kg then 1 mcg/kg/hour; titrate upward; usual: 1 to 3 mcg/kg/hour; some require 5 mcg/kg/hour
---Moderate to severe chronic pain: Transdermal patch: Opioid-tolerant children greater than or equal to 2 years receiving at least 60 mg oral morphine equivalents per day: Initial: 25 mcg/hour system or higher, based on conversion to fentanyl equivalents and administration of equianalgesic dosage (see package insert for further information); use short-acting analgesics for first 24 hours with supplemental PRN doses thereafter (for breakthrough pain); dose may be increased after 3 days, based on the daily dose of supplementary PRN opioids required; use the ratio of 45 mg of oral morphine equivalents per day to a 12.5 mcg/hour increase in transdermal patch dosage; change patch every 72 hours; Note: Dosing intervals less than every 72 hours are not recommended for children and adolescents. Initiation of the transdermal patch in children taking less than 60 mg of oral morphine equivalents per day has not been studied in controlled clinical trials; in open-label trials, children 2 to 18 years of age who were receiving at least 45 mg of oral morphine equivalents per day were started with an initial transdermal dose of 25 mcg/hour (or higher, depending upon equianalgesic dose of opioid received).

Children greater than or equal to 5 years and less than 50 kg:
Patient-controlled analgesia (PCA): IV: Opioid-naive: Note: PCA has been used in children as young as 5 years of age; however, clinicians need to assess children 5 to 8 years of age to determine if they are able to use the PCA device correctly. All patients should receive an initial loading dose of an analgesic (to attain adequate control of pain) before starting PCA for maintenance. Adjust doses, lockouts, and limits based on required loading dose, age, state of health, and presence of opioid tolerance. Use lower end of dosing range for opioid-naive. Assess patient and pain control at regular intervals and adjust settings if needed.

Usual concentration: Determined by weight; some clinicians use the following:
---Children less than 12 kg: 10 mcg/mL
---Children 12 to 30 kg: 25 mcg/mL
---Children greater than 30 kg: 50 mcg/mL
---Demand dose: Usual initial: 0.5 to 1 mcg/kg/dose; usual range: 0.5 to 1 mcg/kg/dose
---Lockout: Usual initial: 5 doses/hour
---Lockout interval: Range: 6 to 8 minutes
---Usual basal rate: 0 to 0.5 mcg/kg/hour

Children greater than 12 years to adult:
Sedation for minor procedures/analgesia: IV: 0.5 to 1 mcg/kg/dose; may repeat after 30 to 60 minutes; or 25 to 50 mcg, repeat full dose in 5 minutes if needed, may repeat 4 to 5 times with 25 mcg at 5 minute intervals if needed. Note: Higher doses are used for major procedures.

Continuous sedation/analgesia:
---Less than 50 kg: Initial IV bolus: 1 to 2 mcg/kg; continuous infusion rate: 1 to 2 mcg/kg/hour
---Greater than 50 kg: Initial IV bolus: 1 to 2 mcg/kg or 25 to 100 mcg/dose; continuous infusion rate: 1 to 2 mcg/kg/hour or 25 to 200 mcg/hour

Patient-controlled analgesia (PCA): IV: Children greater than 50 kg, Adolescents greater than 50 kg, and Adults: Note: All patients should receive an initial loading dose of an analgesic (to attain adequate control of pain) before starting PCA for maintenance. Adjust doses, lockouts, and limits based on required loading dose, age, state of health, and presence of opioid tolerance. Use lower end of dosing range for opioid-naive. Assess patient and pain control at regular intervals and adjust settings if needed:

---Usual concentration: 50 mcg/mL
---Demand dose: Usual initial: 20 mcg; usual range: 10 to 50 mcg
---Lockout interval: Usual initial: 6 minutes; usual range: 5 to 8 minutes
---Usual basal rate: less than or equal to 50 mcg/hour

Preoperative sedation, adjunct to regional anesthesia, postoperative pain: IM, IV: 25 to 100 mcg/dose

Adjunct to general anesthesia: Slow IV:
---Low dose: 0.5 to 2 mcg/kg/dose depending on the indication
---Moderate dose: Initial: 2 to 20 mcg/kg/dose; Maintenance (bolus or infusion): 1 to 2 mcg/kg/hour. Discontinuing fentanyl infusion 30 to 60 minutes prior to the end of surgery will usually allow adequate ventilation upon emergence from anesthesia. For "fast-tracking" and early extubation following major surgery, total fentanyl doses are limited to 10 to 15 mcg/kg.
---High dose: 20 to 50 mcg/kg/dose; Note: High dose fentanyl as an adjunct to general anesthesia is rarely used, but is still described in the manufacturer label.

General anesthesia without additional anesthetic agents: IV: 50 to 100 mcg/kg with oxygen and skeletal muscle relaxant

Moderate to severe chronic pain: Transdermal patch: Opioid tolerant patients receiving at least 60 mg oral morphine equivalents per day: Initial: 25 mcg/hour system or higher, based on conversion to fentanyl equivalents and administration of equianalgesic dosage (see package insert for further information); use short-acting analgesics for first 24 hours with supplemental PRN doses thereafter (for breakthrough pain); dose may be increased after 3 days based on the daily dose of supplementary PRN opioids required; use the ratio of 45 mg of oral morphine equivalents per day to a 12.5 mcg/hour increase in transdermal patch dosage; transdermal patch is usually administered every 72 hours but select adult patients may require every 48-hour administration; dosage increase administered every 72 hours should be tried before 48-hour schedule is used.

Adolescents greater than or equal to 16 years to adult: Breakthrough cancer pain: Transmucosal lozenge: Opioid-tolerant patients: Titrate dose to provide adequate analgesia: Initial: 200 mcg; may repeat dose only once, 15 minutes after completion of first dose if needed. Do not exceed a maximum of 2 doses per each breakthrough cancer pain episode; patient must wait at least 4 hours before treating another episode. Titrate dose up to next higher strength if treatment of several consecutive breakthrough episodes requires more than 1 lozenge per episode; evaluate each new dose over several breakthrough cancer pain episodes (generally 1 to 2 days) to determine proper dose of analgesia with acceptable side effects. Once the dose has been determined, consumption should be limited to less than or equal to 4 units/day. Reevaluate maintenance (around-the-clock) opioid dose if patient requires more than 4 units/day. If signs of excessive opioid effects occur before a dose is complete, the unit should be removed from the mouth immediately, and subsequent doses decreased.

Renal Dose Adjustments

CrCl less than 10 mL/min: The dose should be reduced to 50% of the normal dose.

CrCl 10 to 50 mL/min: The dose should be reduced to 75% of the normal dose.

Liver Dose Adjustments

Use with caution. Specific dose adjustment guidelines are not available. However, a lower dose is recommended.

Dose Adjustments

To convert patients from oral or parenteral opioids to fentanyl patch use the following methodology: 1. Calculate the previous 24-hour analgesic requirement. 2. Convert this amount to the equianalgesic morphine dose using Table in other comments section. 3. Use the following table to find the calculated 24-hour morphine dose and the corresponding fentanyl patch dose. FENTANYL DOSE BASED ON TOTAL DAILY MORPHINE DOSE:

ORAL MORPHINE 45 to 134 MG/DAY or IM MORPHINE 23 to 37 MG/DAY = FENTANYL 25 MCG/HR
ORAL MORPHINE 135 to 224 MG/DAY or IM MORPHINE 8 to 22 MG/DAY = FENTANYL 50 MCG/HR
ORAL MORPHINE 225 to 314 MG/DAY or IM MORPHINE 38 to 52 MG/DAY = FENTANYL 75 MCG/HR
ORAL MORPHINE 315 to 404 MG/DAY or IM MORPHINE 53 to 67 MG/DAY = FENTANYL 100 MCG/HR
ORAL MORPHINE 405 to 494 MG/DAY or IM MORPHINE 68 to 82 MG/DAY = FENTANYL 125 MCG/HR
ORAL MORPHINE 495 to 584 MG/DAY or IM MORPHINE 83 to 97 MG/DAY = FENTANYL 150 MCG/HR
ORAL MORPHINE 585 to 674 MG/DAY or IM MORPHINE 98 to 112 MG/DAY = FENTANYL 175 MCG/HR
ORAL MORPHINE 675 to 764 MG/DAY or IM MORPHINE 113 to 127 MG/DAY = FENTANYL 200 MCG/HR
ORAL MORPHINE 765 to 854 MG/DAY or IM MORPHINE 128 to 142 MG/DAY = FENTANYL 225 MCG/HR
ORAL MORPHINE 855 to 944 MG/DAY or IM MORPHINE 143 to 157 MG/DAY = FENTANYL 250 MCG/HR
ORAL MORPHINE 945 to 1034 MG/DAY or IM MORPHINE 158 to 172 MG/DAY = FENTANYL 275 MCG/HR
ORAL MORPHINE 1035 to 1124 MG/DAY or IM MORPHINE 173 to 187 MG/DAY = FENTANYL 300 MCG/HR

Initiate fentanyl patch treatment using the recommended dose and titrate patients upwards (no more frequently than every 3 days after the initial dose or than every 6 days thereafter) until analgesic efficacy is attained. If the patient needs more than 4 units per 24 hours of the transmucosal preparation for breakthrough pain control, titrate dosage upward to the next larger dose. Give each transmucosal unit no sooner than every 30 minutes. Buccal Tablet - Increasing the Dose: From an initial dose, patients should be closely followed and the dosage strength changed until the patient reaches a dose that provides adequate analgesia with tolerable side effects using a single fentanyl buccal tablet. Patients should record their use of fentanyl buccal tablet over several episodes of breakthrough pain and discuss their experience with their physician to determine if a dosage adjustment is warranted. Titration should be initiated using multiples of the 100 mcg fentanyl buccal tablet. Patients needing to titrate above 100 mcg can be instructed to use two 100 mcg tablets (one on each side of the mouth in the buccal cavity). If this dose is not successful in controlling the breakthrough pain episode, the patient may be instructed to place two 100 mcg tablets on each side of the mouth in the buccal cavity (total of four 100 mcg tablets). Although not bioequivalent, four 100 mcg fentanyl buccal tablet tablets were found to deliver approximately 12% and 13% higher values for Cmax and AUC, respectively, compared to one 400 mcg fentanyl buccal tablet. Consequently, patients converting from four 100 mcg tablets to one 400 mcg fentanyl buccal tablet would be expected to experience a decrease in plasma concentration. The impact of this decrease on pain relief has not been evaluated clinically. Titrate above 400 mcg by 200 mcg increments bearing in mind that 1) using more than 4 tablets simultaneously has not been studied and 2) it is important to minimize the number of strengths available to patients at any time to prevent confusion and possible overdose. To reduce the risk of overdose during titration, patients should have only one strength fentanyl buccal tablet available at any one time. Patients should be strongly encouraged to use their entire quantity fentanyl buccal tablets of one strength prior to being prescribed the next strength. If this is not practical, unused fentanyl buccal tablet should be disposed of safely. Once a successful dose has been established, if the patient experiences greater than four breakthrough pain episodes per day, the dose of the maintenance (around-the-clock) opioid used for persistent pain should be re-evaluated. Dosage Adjustment: Dosage adjustment of both fentanyl buccal tablet and the maintenance (around-the-clock) opioid analgesic may be required in some patients in order to continue to provide adequate relief of breakthrough pain. Generally, the fentanyl buccal tablet dose should be increased when patients require more than one dose per breakthrough pain episode for several consecutive episodes.

For patients no longer requiring opioid therapy, discontinuing fentanyl nasal spray along with a gradual downward titration of other opioids should be considered to minimize possible withdrawal effects.

Fentanyl nasal spray therapy can usually be discontinued immediately in patients who continue to take their chronic opioid therapy for persistent pain but no longer require treatment for breakthrough pain.

Precautions

Initial doses should be reduced in elderly or debilitated patients. To convert patients to another opioid, remove fentanyl and titrate the dose of the new analgesic based upon the patient's report of pain until adequate analgesia has been attained. Upon system removal, 17 hours or more are required for a 50% decrease in serum fentanyl levels. For patients requiring discontinuation of opioids, a gradual downward titration is recommended since it is not known what dose level the opioid may be discontinued without producing the signs and symptoms of abrupt withdrawal.

The IV injection must be administered very slowly to avoid paralysis of the muscles of respiration and/or apnea.

Withdrawal symptoms have been reported in the newborn treated with continuous infusion for 5 days or greater.

Patients should be advised that the fine mist spray of fentanyl nasal spray is not always felt on the nasal mucosal membrane and to rely on the audible click and the advancement of the dose counter to confirm a spray has been administered.

Fentanyl nasal spray is used only for the management of breakthrough pain in cancer patients 18 years of age and older who are already receiving and who are tolerant to opioid therapy for underlying persistent cancer pain. Patients considered opioid tolerant are those who are taking at least 60 mg of oral morphine/day, 25 mcg of transdermal fentanyl/hour, 30 mg of oxycodone/day, 8 mg oral hydromorphone/day, 25 mg oral oxymorphone/day, or an equianalgesic dose of another opioid for one week or longer. There are differences in the pharmacokinetics of fentanyl nasal spray relative to other fentanyl products which could potentially result in clinically important differences in the amount of fentanyl absorbed and could result in a fatal overdose. Directions for safely converting patients to fentanyl nasal spray from other fentanyl products are not currently available. (Note: This includes oral, transdermal, or parenteral formulations). Therefore, for opioid-tolerant patients starting treatment for breakthrough pain, the initial dose of fentanyl nasal spray is 100 mcg. Each patient dose should be titrated to provide adequate analgesia while minimizing side effects.

Safety and effectiveness of fentanyl sublingual, fentanyl nasal spray, and fentanyl sublingual spray have not been established in pediatric patients (less than 18 years of age).

Other Comments

The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for extended-release and long-acting opioid analgesics and transmucosal immediate-release fentanyl products. Both of the REMS consist of a medication guide and elements to assure safe use; the transmucosal products also include an implementation system. Additional information is available at www.fda.gov/Drugs/DrugSafety/postmarketDrugSafetyInformationforPatientsandProviders/ucm111350.htm.

The efficacy of the 12 mcg/hour transdermal patch as an initiating dose has not been determined.

Each fentanyl patch may be worn continuously for 72 hours. If analgesia for more than 72 hours is required, a new system should be applied to a different skin site after removal of the previous transdermal system. For delivery rates in excess of 100 mcg/hour, multiple systems may be used.

During the initial application of fentanyl, patients should use short-acting analgesics for the first day as needed. Thereafter, some patients still may require periodic supplemental doses of other short-acting analgesics for 'breakthrough' pain.

Buccal Tablet - Patients should remove the tablet from the blister unit and immediately place the entire fentanyl buccal tablet in the buccal cavity (above a rear molar, between the upper cheek and gum). Patients should not attempt to split the tablet. The fentanyl buccal tablet should not be sucked, chewed or swallowed, as this will result in lower plasma concentrations than when taken as directed. The fentanyl buccal tablet should be left between the cheek and gum until it has disintegrated, which usually takes approximately 14 to 25 minutes. After 30 minutes, if remnants from the fentanyl buccal tablet remain, they may be swallowed with a glass of water. The length of time that the tablet takes to fully disintegrate following buccal administration does not appear to affect early systemic exposure to fentanyl.
