The Buzz: Text message-based reminder system for OCP use does not seem to improve adherence.
Citation: Hou MY et al. Using daily text-message reminders to improve adherence with oral contraceptives: A randomized controlled trial. Obstet Gynecol 2010 Sep; 116:633.
Summary: Study authors randomized 82 predominantly white, all high-school graduate new or resuming OCP users to to receive daily text-message reminders or no reminders for three cycles. The number of missed pills per cycle was the same in both groups (around 4.5/month). There were no pregnancies in either group.
Commentary: The high rate of missed pills reported in this study suggests that even with advanced reminder systems, many women on OCPs are at higher risk for pregnancy then we might think. OCPs are still a valid option, but this study may aid in shared decision-making around optimal methods.
