The Food and Drug Administration is warning against cooking chicken in NyQuil after at least one video went viral of someone dousing poultry in cold medicine on a stovetop.

“The challenge sounds silly and unappetizing — and it is,” the FDA warning last week said. “But it could also be very unsafe.”

The FDA says boiling medication can make it much more concentrated and that people could ingest dangerous levels of the drugs simply by inhaling the vapors, hurting their lungs.  

NyQuil’s ingredients are acetaminophen, dextromethorphan, and doxylamine.

The FDA referred to it as a “video challenge,” but it’s unclear if the video was intended to be a challenge, whether it ever reached “trend” status or if anyone became ill as a result.

As of Wednesday morning, TikTok had blocked search results for “NyQuil chicken” or “sleepy chicken,” as it was being called. Search attempts led to a message saying: “Some online challenges can be dangerous, disturbing, or even fabricated. Learn how to recognize harmful challenges so you can protect your health and well-being.”

The top search results using misspellings — a common tactic used to evade content moderation — found mostly videos of users reacting in disbelief to the “challenge” or poking fun at it.

According to Forbes, one video, which has since been removed, included the narrator saying, “Sometimes the steam really makes you sleepy.” The narrator explains, “Season that NyQuil in there just at the right temperature. You want to let it sit there and let it sizzle for about five to 30 minutes,” adding, “What you are looking for is that blue color.”

The FDA urged parents to keep over-the-counter and prescription drugs away from children and lock up medications to prevent accidental overdoses. It also recommended parents discuss with their kids the dangers of misusing drugs and the harm that can come from some social media trends.

Procter & Gamble, the maker of NyQuil, said in a statement to Spectrum News on Wednesday that “consumer safety is our number one priority, and we do not endorse any inappropriate use of our product.” It stressed NyQuil should be used only as directed.

TikTok did not immediately respond to an email seeking comment.

Past dangerous TikTok challenges have involved people eating Tide detergent pods, using the over-the-counter allergy medicine Benadryl to induce hallucinations and pressing a penny against a phone charger plugged halfway into a wall outlet.
