Potential risk of drug-drug interactions with hormonal contraceptives and antiretrovirals: prevalence in women living with HIV.

Background: Family planning services are vital for women living with HIV (WLH); however, the use of concomitant antiretroviral therapy (ART) and hormonal contraceptives (HCs) may pose challenges due to the risk of potential drug-drug interactions (DDIs). The objectives of this study were to assess ART and HC use among WLH and quantify the frequency of potential DDIs between ART and HCs.

Methods: This was a retrospective, observational, cohort study of WLH aged 18-55 years, prescribed ART, with at least one clinic visit from January 1, 2010 to April 30, 2014.
