FDA Strengthens TIRF Opioid Product REMS

Share

FDA says it has taken steps to strengthen the Risk Evaluation and Mitigation Strategies (REMS) program for transmucosal immediate-release fentanyl (TIRF) products to help ensure that the drugs’ benefits continue to outweigh their risks. An agency statement says that despite the decline in the use of TIRF products in recent years, data have suggested that prescribing TIRF medicines still occurs in patients who are not opioid-tolerant.

“With this in mind, FDA finalized modifications to the REMS program to address the persistence of these concerning prescribing practices,” the statement says. “These changes will also improve our ability to monitor for adverse events and ensure safe use of these medicines.”

The agency says the program has been strengthened to require: 

  •          prescribers to document a patient’s opioid tolerance with each prescription of a TIRF medicine for outpatient use;
  •          outpatient pharmacies dispensing TIRF medicines to document and verify a patient’s opioid tolerance before dispensing;
  •          require inpatient pharmacies to develop internal policies and procedures to verify opioid tolerance in patients who require TIRF medicines while hospitalized; and
  •          development of a new patient registry for use, along with other data sources, to monitor for accidental exposure, misuse, abuse, addiction, and overdose.
