Kim Kardashian promotes morning sickness medicine

Kim Kardashian is gushing about the benefits of a morning sickness medication just weeks after insisting she always refuses to promote products online.

The reality TV star told the audience during a question-and-answer session at the Cannes Lions festival in France in June (15) that her Instagram.com account is "off limits" to brands hoping for promotion.

She added, "I can smell a mile away when something is not authentic... I just don't like it when people hold up similar products and post everyday about something different."

However, on Sunday (19Jul15) Kardashian, who is pregnant with her second child with rapper Kanye West, shared a picture of herself holding a bottle of morning sickness medicine and added a caption praising the product.

She writes, "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."
