- Abstract
The article looks at the annual number of oral contraceptive prescriptions dispensed at retail pharmacies in the U.S. From 1981 to 1988, the annual number of oral contraceptive prescriptions dispensed at retail pharmacies in the U.S. remained between 51 and 58 million. The average doses of estrogen and progestin in oral contraceptive prescriptions decreased dramatically between 1964 and 1988. Using information from the National Prescription Audit and the National Disease Therapeutic Index, a pair of databases maintained by IMS America, researchers analyzed trends in oral contraceptive prescriptions between 1964 and 1988. The investigators also looked at trends in "mentions" in 1980,1984 and 1988. The total number of mentions for oral contraceptives increased between 1980 and 1988. Although this is true for all age-groups of women 15-44, the proportion of oral contraceptive mentions to 25-34-year-olds increased from 37 percent of all mentions to women aged 15-44 in 1980 to 45 percent in 1988, while the proportion of mentions to 15-24-year-olds decreased from 57 percent to 48 percent during that period.
