Kim Kardashian may be famous for her selfies, but the Food and Drug Administration wasn't a fan of her latest one.
An Instagram picture featuring Kim, morning sickness drug Diclegis and accompanying text promoting the drug's benefits garnered more than 450,000 "likes" but brought about a formal FDA warning letter for the drug's manufacturer.
Part of the letter says, "The social media post is misleading because it presents various efficacy claims for Diclegis, but fails to communicate any risk information."
The posts promoting the drug have since been taken down, but Kardashian originally claimed the drug made her feel "a lot better and most importantly, it's been studied and there was no increased risk to the baby."
Duchesnay, the pharmaceutical company behind the drug, issued a statement saying it would take quick action in responding to the FDA's letter.
"Duchesnay USA takes its regulatory responsibilities very seriously, and acknowledges that its communications, including in social media as in this particular instance, need to be in accordance with applicable rules and regulations," the company said.
The FDA warning letter also requests Duchesnay offer corrections to the claims "using the same media" for the same audience.
That could mean a corrected selfie for Kim's 42.4 million followers.
Kardashian did not immediately respond to a request for comment from CNBC.
