THE FDA posted a warning letter online Tuesday aimed at a drug company Kim Kardashian has been promoting on social media. Kardashian has been promoting a prescription pill to treat morning sickness called Diclegis without mention of the drugβs various side effects. βI tried changing things about my lifestyle, like my diet, but nothing helped, so I talked to my doctor,β Kardashian wrote in a post on Instagram and Facebook. βHe prescribed me #Diclegis, and I felt a lot better and most importantly, itβs been studied and there was no increased risk to the baby.β The FDAβs warning, addressed to the CEO of drugmaker Duchesnay Inc., calls for the company to remove the social media posts immediately and outline a plan to prevent future posts like it.
