Abstract
Importance
The US Supreme Court Dobbs v Jackson Women’s Health Organization decision
allowed states to strengthen restrictions on abortion access, triggering the closure of family planning
clinics and leading to confusion about the legality of emergency contraceptives (ECs).
Objectives
To evaluate the association between the Dobbs decision and fills for oral and
emergency contraceptives in states that enacted the most restrictive abortion policies after Dobbs.
Design, setting, and participants
This cohort study used data on contraceptive fills for women of reproductive age (15-49 years) in the US from IQVIA’s National Prescription Audit Payer Trak and data from the Guttmacher Institute were used to categorize changes in abortion restrictions in each state. A difference-in-differences analysis compared changes in monthly fill rates for daily oral contraceptive pills (OCPs) and ECs in states that became most restrictive (implemented a full abortion ban after Dobbs) and comparison states (kept a medium level of abortion restrictions after Dobbs) before (March 2021 to November 2021) and after (July 2022 to October 2023) the Dobbs decision.
Exposure
State-level abortion restrictions.
Main outcomes and measures
Monthly fills of OCPs and ECs per 100 000 women of reproductive age.
Results
Between March 2021 and October 2023, 142.8 million prescriptions for OCPs and 904 269 prescriptions for ECs were dispensed at US retail pharmacies. Before Dobbs, trends in monthly fill rates were similar for OCPs and ECs between the most restrictive and comparison states. After the Dobbs decision, states that became the most restrictive experienced an additional 4.1% decline in OCP fills with 285.9 fewer fills per 100 000 (95%CI, −495.8 to −6.8; P = .04). In contrast to OCPs, fills for ECs increased during the first year after Dobbs (July 2022 to June 2023) in both groups of states. However, 1 year after Dobbs (July 2023 to October 2023), the most restrictive states experienced an additional 65%decrease in emergency contraceptive fills with 13.2 fewer fills per 100 000 (95%CI, −27.2 to −4.1; P = .01).
Conclusions and relevance
In this cohort study of prescriptions filled at US pharmacies, the Dobbs decision was associated with declines in oral contraceptives, particularly ECs, in states enacting the most restrictive abortion policies. Given the important role of OCPs and ECs in preventing pregnancy and the need for abortion, efforts to improve access may be needed, especially in states where legal abortion is no longer an option.
