Brief summary

The purpose of this study is to determine whether getting more packs of birth control pills leads to improved continuation, when compared with getting the traditional supply.

Detailed description

Discontinuation of oral contraceptive use in the initial months is common; successful early continuation is predictive of long term continuation and prevention of unintended pregnancy. The conventional approach to initiation of hormonal contraceptives in publicly funded clinics across the United States is to give the patient a limited supply of OCs, or a prescription with a limited number of refills, and then have her return to the clinic for a refill. This approach requires the patient to make frequent visits to the clinic, a barrier to method continuation. This randomized trial will evaluate a simple but potentially powerful change in family planning clinic practice, i.e., the effect of dispensing more versus fewer cycles of oral contraception (OC). The study will be carried out in an urban, publicly funded family planning clinic that serves a population that is poor, young and primarily Hispanic or AfricanAmerican. This population was targeted as its members are at increased risk of discontinuing contraception in the first year of use.

Interventions
