REMS

Also called Risk Evaluation and Mitigation Strategy, REMS program, restricted distribution program · Reviewed

Definition: A REMS (Risk Evaluation and Mitigation Strategy) is a drug safety program FDA can require for certain medicines with serious safety concerns, to help make sure the benefits outweigh the risks. FDA says only a few medicines need one. It targets one specific serious risk rather than every side effect.

How it differs from the label

FDA says every medicine has labeling that tells providers about its risks, and that most adverse events are covered there, in the prescribing information. A REMS adds actions on top: it focuses on preventing, monitoring or managing one serious risk by informing, educating or reinforcing steps that make it rarer or less severe. Some programs limit who can prescribe or dispense the drug.

Examples from labels on this site

Two REMS programs on current US labels
ProductRiskWhat the program requires
Aveed (testosterone undecanoate)Oil microembolism in the lungs (POME) and anaphylaxis during or after an injectionCertified prescribers and health care settings; 30 minutes of observation after each shot
Qsymia (phentermine and topiramate)Birth defects, including cleft lip or palateDispensed only by certified pharmacies; pregnancy test before starting and monthly

FDA's own example is Zyprexa Relprevv, a long-acting injection that may only be given in certified facilities that can watch patients for at least 3 hours.

Why it matters for your log

A REMS can shape where and when you get a dose. With Aveed, for example, every shot happens in a certified clinic with a wait afterwards. Logging the date and site of each clinic dose keeps your history complete even when you do not inject it yourself.
