REMS (Risk Evaluation and Mitigation Strategy)

A Risk Evaluation and Mitigation Strategy (REMS) is an FDA-required drug safety program for certain medications with serious safety concerns, designed to ensure that the benefits of the drug outweigh its risks through specific requirements such as medication guides, communication plans, and restricted dispensing programs.

Exam Tip

REMS adds product-specific safety controls; not every program has enrollment or lab requirements. ETASU can include restricted dispensing and certification. iPLEDGE remains an example. Clozapine REMS was removed June 13, 2025; ANC monitoring under labeling remains recommended.

What Is REMS?

A risk evaluation and mitigation strategy (REMS) is an FDA-required safety program for a particular drug or group of drugs when additional measures are necessary to ensure benefits outweigh risks. A boxed warning or Medication Guide alone does not establish that a current REMS exists.

Possible Program Elements

ElementPurpose
Medication Guide or patient informationCommunicate approved safety information when part of the program
Communication planInform healthcare providers about specified risks and actions
Elements to assure safe use (ETASU)May require certification, restricted dispensing, patient enrollment, or documented safe-use conditions
Implementation systemSupports monitoring and implementation of specified ETASU

Programs differ. Not every REMS requires enrollment, pharmacy certification, or laboratory results. Check the current FDA listing and the exact product's program before dispensing.

Examples and a Removed Program

Drug/programKey distinction
Isotretinoin / iPLEDGEA current REMS addressing embryo-fetal toxicity; follow current enrollment, pregnancy-testing, and authorization rules
MifepristoneIts REMS includes certified prescribers and certified dispensing pharmacies, with a patient agreement
ClozapineFDA removed the REMS effective June 13, 2025; enrollment and ANC submission to the former program are no longer dispensing requirements

Removal of the clozapine REMS does not remove the neutropenia risk. Prescribers should continue ANC monitoring according to the prescribing information. The pharmacy must follow current labeling and clinical review requirements without treating the removed program as active.

Technician Responsibilities

  • Identify whether the actual product has a current REMS.
  • Assist with the specific administrative checks required by that program.
  • Refer laboratory interpretation, clinical eligibility, and counseling to the pharmacist or prescriber.
  • Distribute required patient information and document authorized actions.
  • Escalate missing program authorization before completing dispensing.

Exam Alert

Distinguish ordinary labeling requirements from additional REMS controls. Learn ETASU and recognize iPLEDGE as an example, while remembering that REMS programs can change or be removed.
