Over-dosage with thalidomide was unlikely to prove fatal. It was marketed in Europe and in Britain as a "safe sedative". The tragic results that followed its use by women in the early weeks of pregnancy are how well known. Babies were born with severe deformities of limbs, internal organs or both. That effect could not have been foretold from any animal tests in use at that time. Since that date new drugs have been subjected to strict testing in various animal species to check the effect on foetal development, along with the older tests for toxicity which had always been undertaken by well-known drug companies
