Black Box Warnings

What is a black box warning?

A life-threatening adverse event that may result from taking a particular medication

  • This is the most serious warning granted by the FDA (Food and Drug Administration)1
  • This warning is denoted by a black box around its perimeter
  • These adverse events are typically witnessed after the drug has been released on the market
  • A black box warning is required if a fatal adverse event (risk) should be considered versus the benefit of taking the medication2

 

Where should I go to find information about black box warnings?

 

Should I be concerned about taking my medication if it has a black box warning?

  • Black box warnings are important to be aware of, but the adverse event in a black box warning rarely occurs.
  • Talk to your pharmacist or prescriber about how serious the black box warning is in comparison to your disease state.
