Inadvertent pregnancies in oral contraceptive users.
Two hundred and nine inadvertent pregnancies in oral contraceptive users were studied to determine the associated factors. The percentage of Pill types also were compared with the market usage over the same period. We found that the classically-suggested cofactors, such as missed pills, late pills, drug ingestion, and gastrointestinal upsets were reported commonly. The triphasic Pills also were represented more frequently than would have been expected from their share of the market.
