Kim Kardashian in hot water over morning sickness meds

The drug makers behind a morning sickness medication touted by Kim Kardashian have been accused of misbranding.

They have also been ordered to cease false promotion or pull the product from shelves.

Kardashian gushed about the benefits of Diclegis in a social media post last month, when she revealed she had signed on as a spokesperson for the brand after taking the pills to combat her own pregnancy ailments.

However her posts on Instagram, which also ran on her Facebook and Twitter pages, have run foul with authorities.

"Have you heard about this? As you guys know my #morningsickness has been pretty bad. I tried changing things about my lifestyle, like my diet, but nothing helped, so I talked to my doctor. He prescribed me #Diclegis, I felt a lot better and most importantly, it's been studied and there was no increased risk to the baby. I'm so excited and happy with my results that I'm partnering with Duchesnay USA to raise awareness about treating morning sickness," she wrote.

The posts have since been taken down.

But the publicity hungry reality TV star's online endorsement landed makers at the Duchesnay pharmaceutical company in trouble with officials at America's Food and Drug Administration (FDA), as it failed to include the required health and safety warnings.

FDA officials sent a "warning letter" to Duchesnay bosses last week, branding Kardashian's posts "misleading because it presents various efficacy claims for Diclegis, but fails to communicate any risk information".

They have ordered Duchesnay executives to "immediately cease misbranding" the drug or remove it from the market.

Kardashian, who is due to give birth to a boy in December, has since removed the posts in question from her Instagram and Facebook accounts, although her tweet still remains online.

She has yet to comment on the controversy.
