OTFC is an opioid agonist indicated for the management of breakthrough pain in cancer patients 16 years of age and older who are already receiving and who are tolerant to around-the-clock opioid therapy for their underlying persistent cancer pain. ( 1 ) Patients considered opioid tolerant are those who are taking, for one week or longer, around-the-clock medicine consisting of at least 60 mg of oral morphine per day, at least 25 mcg of transdermal fentanyl per hour, at least 30 mg of oral oxycodone per day, at least 8 mg of oral hydromorphone per day, at least 25 mg oral oxymorphone per day, at least 60 mg of oral hydrocodone per day, or an equianalgesic dose of another opioid. Patients must remain on around-the-clock opioids while taking OTFC. Limitations of Use: Not for use in opioid non-tolerant patients. Not for use in the management of acute or postoperative pain, including headache/migraine or dental pain. ( 4 ) As a part of the TIRF REMS, OTFC may be dispensed by outpatient pharmacies only to outpatients enrolled in the program. ( 5.7 ) For inpatient administration of OTFC, patient and prescriber enrollment are not required. Dosage and administration 2 DOSAGE AND ADMINISTRATION Patients must require and use around-the-clock opioids when taking OTFC. ( 1 ) OTFC should be prescribed only by healthcare professionals who are knowledgeable about the use of opioids and how to mitigate the associated risks. ( 2.1 ) Use the lowest effective dosage for the shortest duration of time consistent with individual patient treatment goals. Reserve titration to higher doses of OTFC for patients in whom lower doses are insufficiently effective and in whom the expected benefits of using a higher dose opioid clearly outweigh the substantial risks. ( 2.1 , 5 ) Initiate the dosing regimen for each patient individually, taking into account the patient’s underlying cause and severity of pain, patient response, prior analgesic experience, and risk factors for addiction, abuse, and misuse. ( 2.1 , 5.1 ) Respiratory depression can occur at any time during opioid therapy, especially when initiating and following dosage increases with OTFC. Consider this risk when selecting an initial dose and when making dose adjustments. ( 2.1 , 5.2 ) Discuss opioid overdose reversal agents and options for acquiring them with the patient and/or caregiver both when initiating and renewing treatment with OTFC, especially if the patient has additional risk factors for overdose, or close contacts at risk for exposure and overdose. ( 2.2 , 5.1 , 5.2 , 5.4 ) Initial dose of OTFC: 200 mcg. Prescribe an initial supply of six 200 mcg OTFC units. ( 2.3 ) Individually titrate to a tolerable dose that provides adequate analgesia using single OTFC dosage unit per breakthrough cancer pain episode. ( 2.4 ) No more than two doses can be taken per breakthrough pain episode. ( 2.4 , 2.5 ) Wait at least 4 hours before treating another episode of breakthrough pain with OTFC. ( 2.4 , 2.5 ) Limit consumption to four or fewer units per day once successful dose is found. ( 2.5 ) Periodically reassess patients receiving OTFC to evaluate the continued need for opioid analgesics to maintain pain control, for the signs or symptoms of adverse reactions, and for the development of addiction, abuse, or misuse. ( 2.5 ) When opioid therapy is no longer required, consider discontinuing OTFC along with a gradual downward of other opioids to minimize possible withdrawal effects. ( 2.7 ) 2.1 Important Dosage and Administration Instructions Healthcare professionals who prescribe Oral Transmucosal Fentanyl Citrate (OTFC) for outpatients must enroll in the TIRF REMS and comply with the requirements of the REMS to ensure safe use of OTFC [se
Boxed Warning
WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF ORAL TRANSMUCOSAL FENTANYL CITRATE (OTFC) Addiction, Abuse, and Misuse Because the use of OTFC exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death, assess each patient’s risk prior to prescribing and reassess all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions ( 5.1 )]. Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has occurred in patients treated with Oral Transmucosal Fentanyl Citrate (OTFC), including following use in opioid non-tolerant patients and improper dosing. Evaluate patients for respiratory depression, especially during initiation of OTFC or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of OTFC are essential. The substitution of OTFC for any other fentanyl product may result in fatal overdose [see Warnings and Precautions ( 5.2 )]. Due to the risk of respiratory depression, OTFC is contraindicated in the management of acute or postoperative pain including headache/migraine and in opioid non-tolerant patients [see Contraindications ( 4 )]. Accidental Ingestion Accidental ingestion of even one dose of OTFC, especially by children, can result in a fatal overdose of fentanyl. Death has been reported in children who have accidentally ingested OTFC. OTFC must be kept out of reach of children [see Warnings and Precautions ( 5.3 )]. Risks From Concomitant Use with Benzodiazepines or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of OTFC and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate [see Warnings and Precautions ( 5.4 ), Drug Interactions ( 7 )]. Risk of Medication Errors Substantial differences exist in the pharmacokinetic profile of OTFC compared to other fentanyl products that result in clinically important differences in the extent of absorption of fentanyl and that could result in fatal overdose [see Dosage and Administration ( 2.1 ), Warnings and Precautions ( 5.5 )]. When prescribing, do not convert patients on a mcg per mcg basis from any other fentanyl products to OTFC [see Dosage and Administration ( 2.1 )]. When dispensing, do not substitute an OTFC prescription for other fentanyl products. Cytochrome P450 3A4 Interaction The concomitant use of OTFC with all cytochrome P450 3A4 inhibitors may result in an increase in fentanyl plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in fentanyl plasma concentration. Evaluate patients at frequent intervals receiving OTFC and any CYP3A4 inhibitor or inducer [see Warnings and Precautions ( 5.6 ), Drug Interactions ( 7 ), Clinical Pharmacology ( 12.3 )]. Risk Evaluation and Mitigation Strategy (REMS) Because of the risk for accidental exposure, misuse, abuse, addiction, and overdose, OTFC is available only through a restricted program required by the Food and Drug Administration, called a Risk Evaluation and Mitigation Strategy (REMS). Under the Transmucosal Immediate Release Fentanyl (TIRF) REMS, pharmacies, outpatients, and healthcare professionals who prescribe to outpatients must enroll in the program. Inpatient pharmacies must develop policies and procedures to verify opioid tolerance in inpatients who require OTFC while hospitalized. Further information is available at www.TIRFREMSAccess.com or by calling 1-866-822-1483 [see Warnings and Precautions ( 5.7 )]. Neonatal Opioid Withdrawal Syndrome (NOWS) Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery [see Warnings and Precautions ( 5.8 )]. WARNING: SERIOUS AND LIFE-THREATENING RISKS FROM USE OF OTFC See full prescribing information for complete boxed warning. OTFC exposes users to risks of addiction, abuse, and misuse, which can lead to overdose and death. Assess patient’s risk before prescribing and reassess regularly for these behaviors and conditions. ( 5.1 ) Serious, life-threatening, or fatal respiratory depression has occurred in patients treated with OTFC, including following use in opioid non-tolerant patients and improper dosing. Regularly evaluate patients, especially upon initiation or following a dosage increase. To reduce the risk of respiratory depression, proper dosing and titration of OTFC are essential. The substitution of OTFC for any other fentanyl product may result in fatal overdose. Due to the risk of fatal respiratory depression, OTFC is contraindicated in opioid non-tolerant patients and in management of acute or postoperative pain, including headache/migraines. ( 1 , 4 , 5.2 ) Accidental ingestion of OTFC, especially by children, can result in a fatal overdose of fentanyl. Keep out of reach of children. Ensure proper storage and disposal. ( 2.8 , 5.3 ) Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate. ( 5.4 , 7 ) Advise pregnant women using opioids for an extended period of time of the risk of Neonatal Opioid Withdrawal Syndrome, which may be life-threatening if not recognized and treated. Ensure that management by neonatology experts will be available at delivery . ( 5.8 ) OTFC is available only through a restricted program called the TIRF REMS. Pharmacies, outpatients, and healthcare professionals who prescribe to outpatients are required to enroll in the program. Patients must be opioid tolerant to receive a TIRF medicine ( 5.7 ) When prescribing, do not convert patients on a mcg per mcg basis from any other fentanyl product to OTFC. ( 5.5 ) When dispensing, do not substitute with any other fentanyl products. ( 5.5 ) Concomitant use with CYP3A4 inhibitors (or discontinuation of CYP3A4 inducers) can result in a fatal overdose of fentanyl. ( 5.6 , 7 , 12.3 )
Monitoring
- • 5 WARNINGS AND PRECAUTIONS Opioid-Induced Hyperalgesia and Allodynia : Opioid-Induced Hyperalgesia (OIH) occurs when an opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain.
- • If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic or opioid rotation.
- • ( 5.9 ) Serotonin Syndrome : Potentially life-threatening condition could result from concomitant serotonergic drug administration.
- • Discontinue OTFC if serotonin syndrome is suspected.
Interaction Notes
- • 7 DRUG INTERACTIONS Table 3 includes clinically significant drug interactions with Oral Transmucosal Fentanyl Citrate (OTFC).
- • Table 3: Clinically Significant Drug Interactions with OTFC Inhibitors of CYP3A4 Clinical Impact: The concomitant use of OTFC and CYP3A4 inhibitors can increase the plasma concentration of fentanyl, resulting in increased or prolonged opioid effects, particularly when an inhibitor is added after a stable dose of OTFC is achieved [see Warnings and Precautions ( 5.6 )] .
- • After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the fentanyl plasma concentration will decrease [see Clinical Pharmacology ( 12.3 )] , resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to fentanyl.
- • Intervention: If concomitant use is necessary, consider dosage reduction of OTFC until stable drug effects are achieved.
