Celebrity socialite Kim Kardashian has taken to social media platforms to promote Diclegis, a new morning sickness drug that combines vitamin B6 with an antihistamine. Diclegis was formerly on the market under the name Benedicten until it was pulled from the shelves in 1983 after fears of birth defects surfaced.
Several anti-nausea drugs have been used to treat morning sickness despite fears that taking the drugs could lead to birth defects. Most recently, popular anti-nausea drug Zofran has been linked to an increased risk of birth defects among women who use the drug during pregnancy.
Zofran has only been approved to treat nausea in post-surgery and cancer patients, though doctors have increasingly prescribed the drug to treat morning sickness. At least three studies have since linked the drug to an increased risk of serious defects, including cleft palate defects, heart defects and other congenital birth defects.
