Objective: To evaluate pregnancy complication rates and related charges in users of 84/7, 21/7 and 24/4 combined oral contraceptives (COCs).
Study design: Data were obtained from the i3 InVision Data Mart™ retrospective claims database. Subjects were aged 15-40 years, first prescribed a COC between 1/1/2006 and 4/1/2011 and continuously insured for ≥1 year. 84/7 users were matched 1:1 to 21/7 and 24/4 users.
Results: Pregnancy-related complication rates and associated charges were significantly lower with 84/7 vs. 21/7 and 24/4 regimens.
Conclusion: Preliminary data suggest 84/7 regimens may be associated with fewer pregnancy complications and lower related charges.
