Certain high-risk medications can’t be dispensed like a typical prescription. The FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for drugs where the risks require extra controls beyond standard labeling — and pharmacists are often the last checkpoint before a REMS-restricted drug reaches a patient. Here’s how REMS programs generally work and what they require at the pharmacy level.
What a REMS actually is
A REMS is a drug safety program the FDA can require as a condition of approval for certain medications — either at initial approval or later, if new safety signals emerge. It’s a formal risk management strategy layered on top of standard prescribing and dispensing rules, with FDA authority behind it.
Not every drug with black box warnings has a REMS, and having a REMS doesn’t necessarily mean a drug is rarely used — some REMS-restricted drugs, like isotretinoin (iPLEDGE) and certain opioid formulations, are dispensed in meaningful volume across community pharmacies.
Common elements of a REMS program
REMS programs vary significantly depending on the drug and the specific risks being managed, but they typically draw from a defined set of tools:
Medication guides — Patient-facing information that must generally be provided with each dispensing, similar to but distinct from standard counseling.
Communication plans — Materials directed at prescribers and pharmacists to reinforce safe-use conditions.
Elements to Assure Safe Use (ETASU) — The more restrictive tier, which can include:
- Pharmacy, prescriber, or patient certification/enrollment in the REMS program
- Documentation of specific safety criteria before dispensing (such as negative pregnancy tests for isotretinoin)
- Dispensing only in certain healthcare settings
- Patient monitoring and periodic reassessment requirements
Implementation system — In many ETASU-level REMS, this includes an FDA-mandated enrollment and verification system pharmacies must use to confirm dispensing authorization before a prescription can be filled.
The pharmacist’s role in practice
For REMS-restricted drugs with ETASU requirements, pharmacies generally need to be certified with the REMS program itself, separate from any pharmacy or pharmacist license. This typically means:
- Completing REMS-specific training for pharmacy staff
- Enrolling the pharmacy in the drug manufacturer’s REMS system
- Verifying patient and prescriber authorization status before dispensing, often through a dedicated online portal
- Documenting compliance with program-specific requirements at the point of sale
Because ETASU requirements are program-specific, a pharmacist dispensing several different REMS-restricted drugs may be managing several entirely separate certification systems, each with its own portal, training, and documentation requirements.
Why REMS status can affect access and workflow
REMS requirements can meaningfully slow down or restrict dispensing compared to non-REMS medications. Common friction points include:
- Time-sensitive verification windows (e.g., pregnancy test validity periods for isotretinoin)
- Pharmacy certification lapses that block dispensing until resolved
- Limited pharmacy network participation for certain REMS drugs, which can affect where patients can fill prescriptions
- Coordination required between prescriber offices and pharmacies to keep enrollment and documentation current
For pharmacists working across multiple states or multiple pharmacy locations, keeping REMS certifications current at each site is a separate administrative task from state licensure — worth tracking alongside standard DEA registration renewals and other recurring compliance deadlines.
REMS modifications and discontinuation
The FDA can modify or remove REMS requirements over time as new safety data emerges, or in response to petitions from manufacturers or other stakeholders. Pharmacies need to track these changes since dispensing requirements can shift — a drug that required ETASU-level certification may later have those requirements relaxed, or new requirements could be added to an existing REMS.
How this intersects with other compliance obligations
REMS compliance sits alongside, not instead of, standard pharmacy law obligations. A pharmacist dispensing a REMS-restricted controlled substance, for example, still needs to meet standard controlled substance recordkeeping and diversion reporting obligations in addition to REMS-specific requirements — the two frameworks operate independently.
Verify current requirements before dispensing
REMS program details — certification steps, verification windows, and documentation requirements — are set by the FDA and each drug manufacturer, and they can change. This article is a general overview, not dispensing guidance for any specific REMS program. Confirm current requirements through the FDA’s REMS database, the manufacturer’s REMS materials, and your pharmacy’s policies before dispensing any REMS-restricted medication, and consult your state board or legal counsel with questions specific to your practice.

Between REMS certifications, DEA registrations, and state license renewals, pharmacists juggle a lot of recurring deadlines. RxByState helps track state-specific requirements so nothing slips through the cracks. Start your free trial →
