Healthcare professionals who prescribe Oral Transmucosal Fentanyl Citrate (OTFC) on an outpatient basis must enroll in the TIRF REMS Access program and comply with the requirements of the REMS to ensure safe use of OTFC [see Warnings and Precautions (5.10)].
As with all opioids, the safety of patients using such products is dependent on health care professionals prescribing them in strict conformity with their approved labeling with respect to patient selection, dosing, and proper conditions for use.
2.1 Initial Dose
Individually titrate OTFC to a dose that provides adequate analgesia and minimizes side effects. The initial dose of OTFC to treat episodes of breakthrough cancer pain is always 200 mcg. The OTFC unit should be consumed over 15 minutes. Patients should be prescribed an initial titration supply of six 200 mcg OTFC units, thus limiting the number of units in the home during titration. Patients should use up all units before increasing to a higher dose to prevent confusion and possible overdose.
2.2 Dose Titration
From this initial dose, closely follow patients and change the dosage level until the patient reaches a dose that provides adequate analgesia using a single OTFC dosage unit per breakthrough cancer pain episode. If signs of excessive opioid effects appear before the unit is consumed, the dosage unit should be removed from the patient’s mouth immediately, disposed of properly, and subsequent doses should be decreased. Patients should record their use of OTFC over several episodes of breakthrough cancer pain and review their experience with their physicians to determine if a dosage adjustment is warranted.
In cases where the breakthrough pain episode is not relieved 15 minutes after completion of the OTFC unit (30 minutes after the start of the unit), patients may take ONLY ONE additional dose of the same strength for that episode. Thus, patients should take a maximum of two doses of OTFC for any breakthrough pain episode.
Patients must wait at least 4 hours before treating another episode of breakthrough pain with OTFC. To reduce the risk of overdosing during titration, patients should have only one strength of OTFC available at any one time.
2.3 Maintenance Dosing
Once titrated to an effective dose, patients should generally use ONLY ONE OTFC unit of the appropriate strength per breakthrough pain episode.
On those occasions when the breakthrough pain episode is not relieved 15 minutes after completion of the OTFC unit, patient may take ONLY ONE additional dose using the same strength for that episode.
Patients MUST wait at least 4 hours before treating another episode of breakthrough pain with OTFC. Once a successful dose has been found (i.e., an average episode is treated with a single unit), patients should limit consumption to four or fewer units per day.
Dosage adjustment of OTFC may be required in some patients in order to continue to provide adequate relief of breakthrough pain.
Generally, the OTFC dose should be increased only when a single administration of the current dose fails to adequately treat the breakthrough pain episode for several consecutive episodes.
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.
2.4 Administration of OTFC
Open the blister package with scissors immediately prior to product use. The patient should place the OTFC unit in his or her mouth between the cheek and lower gum, occasionally moving the drug matrix from one side to the other using the handle. The OTFC unit should be sucked, not chewed. A unit dose of OTFC, if chewed and swallowed, might result in lower peak concentrations and lower bioavailability than when consumed as directed [see Clinical Pharmacology (12.3)].
The OTFC unit should be consumed over a 15-minute period. Longer or shorter consumption times may produce less efficacy than reported in OTFC clinical trials. If signs of excessive opioid effects appear before the unit is consumed, remove the drug matrix from the patient’s mouth immediately and decrease future doses.
2.5 Discontinuation of OTFC
For patients requiring discontinuation of opioids, a gradual downward titration is recommended because it is not known at what dose level the opioid may be discontinued without producing the signs and symptoms of abrupt withdrawal.
