Overall figures on use are well described, but more detailed use patterns according to type and age need to be updated. <jats:italic>Objectives.<\/jats:italic> To assess trends in the use of OC including progestogen\u2010only pills among Danish women in 1998\u20132010 and to describe in detail use patterns in 2010. <jats:italic>Design.<\/jats:italic> Annual cross\u2010sectional prescription statistics. <jats:italic>Setting.<\/jats:italic> Denmark. <jats:italic>Population.<\/jats:italic> Danish women 10\u201349 years old. <jats:italic>Material and methods.<\/jats:italic> Analysis of prescription data from the National Registry of Medicinal Products Statistics from 1 January 1998 through 31 December 2010. <jats:italic>Results.<\/jats:italic> Combined OC (COC) with 50 \u03bcg estrogen decreased their market share from 3% in 1998 to zero in 2010, and COC with 30\u201340 \u03bcg estrogen decreased to 50% in 2010, in contrast, COC with 20 \u03bcg estrogen increased to 46% in 2010. Progestogen\u2010only pills accounted for 4%. COC with levonorgestrel decreased, while the use of pills with desogestrel and gestodene among two\u2010thirds of current users was constant. <jats:italic>Conclusion.<\/jats:italic> Low\u2010dose COCs gradually replaced middle\u2010dose pills. Pills with newer progestogens are used primarily by young women, and 85% of users in 2010 were on products with desogestrel, gestodene, drospirenone or cyproteroneacetate.
