Diethylstilboestrol, DES, was one of the first synthetic non-steroidal oestrogenic compounds that was developed in 1938. One of the uses of these oestrogenic compounds was in pregnancy to prevent miscarriages and premature births, particularly in those pregnancies that were complicated by diabetes or toxaemia.
Medical preparations containing diethylstilbestrol were available in this country during the 1940s, 1950s, 1960s and 1970s. There is no relevant information available on the level of prescribing or use of diethylstilbestrol during these years. In 1972 and again in 1975, the National Drugs Advisory Board reviewed the position and drew attention to the problems associated with the use of oestrogens and with stilboestrol and recommended that high doses of stilboestrol should not be used during pregnancy.
In 1979 the following medicinal products were authorised by the Minister for Health on the recommendation of the National Drugs Advisory Board for purposes other than use in the course of pregnancy: Boestrol tablets, for the treatment of malignancy and atrophic vaginitis, and Tampovagan Stilboestrol and Lactic Acid Pessaries, for the treatment of atrophic vaginitis, senile or post menopausal disorders. This product was discontinued in 1992 for commercial reasons.
