Hormonal contraceptives are among the most widely used reversible methods of preventing pregnancy. In 2002, oral contraceptive pills (OCPs) were the most popular contraceptive method, used by 11.6 million women in the USA [1]. Unfortunately, for methods such as OCPs, which depend on adherence in order to be effective, there is a large difference in failure rates between perfect use and typical use. For example, the first year failure rate for OCPs with perfect use is only 0.3%, but with typical use it is 8% [2].
