Why We’re Averse to “Adverse”

A doodle looks over their glasses at a pamphlet titled "What you need to know about potential adverse reactions." The doodle says, "I'm having an adverse reaction to this terminology."

Here at We ❤️ Health Literacy Headquarters, we come across the word “adverse” a lot. Adverse drug events, adverse reactions, adverse childhood experiences… it’s a real health jargon regular! And, like most jargon terms, “adverse” has no place in consumer health materials.

Of course, as a health communicator, you’ll often need to communicate about an adverse something-or-other. For example, if you’re describing treatment options for a disease, explaining the potential side effects is really important!

But you can write about risks, side effects, and other unpleasant outcomes without calling them adverse anything! Here are a few simple plain language swaps to use instead.

Try this:

  • Most people have mild side effects from the vaccine.
  • If you have a bad reaction to the medicine, call your doctor right away.
  • Kids who have difficult experiences in childhood are more likely to have health problems as adults.

Not that:

  • Most people have mild adverse events from the vaccine.
  • If you have an adverse reaction to the medicine, call your doctor right away.
  • Kids who have adverse childhood experiences are more likely to have health problems as adults.

The bottom line: Ditch “adverse” in favor of plain language terms like “side effects” and “bad reactions.”

Tweet about it: “Adverse” is a health jargon regular (think “adverse events”) — but it’s not a good fit for #PlainLanguage health materials. @CommunicateHlth suggests some simple swaps: https://bit.ly/3cfJKqE #HealthLit
