Consumer:CycloSPORINE can increase the blood levels and effects of fentaNYL. Contact your doctor if you experience dizziness, confusion, fainting, extreme sedation, slow heart rate, slow or difficult breathing, and shortness of breath. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of fentanyl, which is primarily metabolized by the isoenzyme. Increased fentanyl concentrations could conceivably increase or prolong adverse drug effects and may cause respiratory depression.
MANAGEMENT: Patients receiving fentanyl in combination with CYP450 3A4 inhibitors should be carefully monitored, and dosage adjustments made accordingly if necessary. Patients and/or their caregivers should be advised to seek medical attention if potential signs and symptoms of toxicity occur such as dizziness, confusion, fainting, extreme sedation, bradycardia, slow or difficult breathing, and shortness of breath. Patients treated with transdermal formulations of fentanyl should be cautioned that drug interactions and drug effects may be observed for a prolonged period beyond removal of the patch, as significant amounts of fentanyl are absorbed from the skin for 17 hours or more after the patch is removed.
