Ever since the Thalidomide case fifty years ago, when Thalidomide use by pregnant women resulted in more than 400 disabled babies being born, drug companies have been more than cautious about warning signs for pregnant women.
More than often, the affects of these drugs are not even evaluated or tested on pregnant women but the warnings signs were put anyway. Such attitude led to many women refusing to take certain drugs, like paracetamol and other over-the-counter drugs that are safe to use.

Doctors call for a rethink about this attitude because many women may actually be at risk for not being treated in the best way.

They also said that most of the drugs on the market carry warnings about use during pregnancy although there is no evidence of harm in many cases.
In the end, they advise that pregnant women should consult with their doctors about whether they could be taking certain drugs or not.
