Brand Names: Abstral

What is fentanyl sublingual?

Fentanyl sublingual (under the tongue) is a narcotic pain medicine.

Fentanyl sublingual tablets (Abstral) are used to treat "breakthrough" cancer pain. Abstral is taken together with other non-fentanyl narcotic pain medicine that is used around the clock. Abstral is not for treating pain that is not cancer-related, such as pain from surgery or dental work, migraine headaches, or back pain.

Fentanyl sublingual may also be used for purposes not listed in this medication guide.

What is the most important information I should know about fentanyl?

Do not use Abstral to replace any other form of fentanyl, such as Actiq, Fentora, Onsolis, Duragesic, or generic brands of fentanyl (injection, skin patch, dissolving film, or "lollipop" device).

Before taking fentanyl, tell your doctor if you have a breathing disorder (asthma, wheezing, COPD), slow heartbeats, seizures, mental illness, low blood pressure, liver or kidney disease, a debilitating condition, or a history of head injury, brain tumor, or addiction to drugs or alcohol.

Tell your doctor if there are children living in the home where you will store this medicine. Keep Abstral out of the reach of children. The amount of fentanyl in each Abstral tablet can be fatal to a child. Never share fentanyl with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

What should I discuss with my healthcare provider before taking fentanyl?

Do not take fentanyl unless you are already being treated with a similar opioid pain medicine and your body is tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant. Do not take fentanyl if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. Tell your doctor if there are children living in the home where you will store this medicine. Keep out of the reach of children. The amount of fentanyl in each Abstral tablet can be fatal to a child.

To make sure you can safely take fentanyl sublingual, tell your doctor if you have any of these other conditions:

a breathing disorder such as wheezing, asthma, or chronic obstructive pulmonary disease (COPD);

seizures, epilepsy, or a history of head injury or brain tumor;

low blood pressure, slow heartbeats or other heart rhythm disorder;

mental illness such as depression, schizophrenia, or hallucinations;

liver or kidney disease;

any type of debilitating condition; or

a personal or family history of drug or alcohol addiction.

Fentanyl may be habit-forming and should be used only by the person it was prescribed for. Never share fentanyl with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it. FDA pregnancy category C. It is not known whether fentanyl will harm an unborn baby. Fentanyl may cause breathing problems, seizure, or addiction and withdrawal symptoms in a newborn if the mother takes the medication during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using fentanyl sublingual. Fentanyl may also cause drowsiness, breathing problems, or addiction and withdrawal symptoms in a nursing infant. Do not breast-feed while you are taking fentanyl sublingual. Do not give this medication to anyone under 18 years old.

How should I take fentanyl sublingual (Abstral)?

Use exactly as prescribed. Never use fentanyl in larger amounts, or for longer than recommended by your doctor. Keep using your around-the-clock narcotic pain medicine but never take Abstral together with a second form of fentanyl. Do not use Abstral to replace any other form of fentanyl, such as Actiq, Fentora, Onsolis, Duragesic, or generic brands of fentanyl (injection, skin patch, dissolving film, or "lollipop" device). If you switch to Abstral from another form of fentanyl, you will not use the same dose. You must start with the lowest dose (100 micrograms). Your doctor may change your dose to make sure you get the best results.

To use Abstral sublingual tablets:

Keep the tablet in its blister pack until you are ready to take the medicine. Separate a single blister from the rest of the pack by tearing along the dotted lines, then peel the foil backing off. Do not push a tablet through the foil or you may damage the tablet.

If your mouth is dry, swallow a sip of water before taking the Abstral tablet.

Drop the tablet into the palm of your hand. Using dry fingers, place the tablet under your tongue, as far back as you can. The tablet will begin to dissolve right away.

Do not break, chew, suck, or swallow the tablet whole. Allow it to dissolve in your mouth without chewing. Do not drink or eat anything during this time.

You may use a second tablet 30 minutes after the first. Use only the same strength and amount you used for the first dose.

Call your doctor if you still have pain after taking the second tablet. Do not take more than 2 tablets for each episode of breakthrough cancer pain.

You must wait at least 2 hours after your last dose of Abstral before you can treat a new pain episode.

Do not treat more than 4 pain episodes per day with Abstral. Call your doctor if you have breakthrough pain more than 4 times in one day.

Do not stop taking Abstral or your other narcotic pain medicine without your doctor's advice. Ask your doctor how to avoid withdrawal symptoms when you stop using pain medication. Keep out of the reach of children. The amount of fentanyl in each Abstral tablet can be fatal to a child. Store the blister pack in its original carton at room temperature, away from heat and moisture. Throw away any unused tablets by removing them from the blister pack and flushing them down a toilet. Keep track of the amount of medicine used from each carton. Fentanyl is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.

What happens if I miss a dose?

Since fentanyl sublingual is used as needed, you are not likely to miss a dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A fentanyl overdose can be fatal.

Overdose symptoms may include extreme drowsiness, weak pulse, fainting, and slow breathing (breathing may stop).

What should I avoid while taking fentanyl?

Fentanyl may impair your thinking or reactions. Do not drive or do anything that requires you to be alert. Do not drink alcohol. It can increase drowsiness or breathing problems caused by fentanyl.

Grapefruit and grapefruit juice may interact with fentanyl and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.

Fentanyl side effects

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using fentanyl and call your doctor at once if you have a serious side effect such as:

slow heart rate, weak or shallow breathing, sighing;

confusion, extreme fear, unusual thoughts or behavior; or

feeling like you might pass out.

Less serious side effects may include:

nausea, dry mouth, constipation;

headache, drowsiness, tired feeling; or

white patches or sores inside your mouth or on your lips.

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.

Fentanyl Dosing Information

Usual Adult Dose for Anesthesia:

Premedication for Anesthesia:
50 to 100 mcg IM, 30 to 60 minutes prior to surgery.
Lozenge: 5 mcg/kg (400 mcg is the maximum dose).
Lower doses should be used for vulnerable patients.

General Anesthesia:
Total Low dose: 2 mcg/kg (minor procedures).
Maintenance low dose: Infrequently needed.
Total Moderate dose: 2 to 20 mcg/kg.
Maintenance moderate dose: 25 to 100 mcg IV/IM.
Total high dose: 20 to 50 mcg/kg (prolonged surgeries).
Maintenance high dose: 25 mcg to half of the initial dose.

Adjunct to Regional Anesthesia:
50 to 100 mcg IM or slow IV over 3 to 5 minutes as required.

Postoperative :
50 to 100 mcg IM. May repeat dose in 1 to 2 hours as needed.

Usual Adult Dose for Pain:

Transdermal patch - Initial dose: 25 mcg/hour patch (unless opioid tolerance) every 72 hours.

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.

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.

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.

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.

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

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.
