Did you know the popular hemorrhoid ointment Preparation H was originally developed as a burn relief cream in the 1930s? The fascinating story of **who developed Preparation H** involves a brilliant, multifaceted scientist and a significant rebranding by a major pharmaceutical company.

In December 2005, pharmaceutical company Wyeth made the decision to discontinue Microval, a progestogen-only contraceptive pill containing levonorgestrel. The primary cause for the withdrawal was a commercial decision to rationalize their product portfolio, following a period of supply difficulties, rather than concerns related to the medication's safety or efficacy.

According to the European Medicines Agency (EMA), manufacturer Wyeth voluntarily withdrew its applications for Pristiq (desvenlafaxine) in Europe in 2008 after regulators expressed concerns over the drug's efficacy and risk-benefit profile. This was a withdrawal of applications for marketing authorization, not a ban, and it is the key reason **why did Europe ban Pristiq** is a misconception.
