Ulipristal acetate emergency contraception (EC), sold under the brand name Ella, is a highly effective, well tolerated form of oral EC. It is available for sale by prescription, but some pharmacies and clinics may not carry Ella. This document lists the retail pharmacies in Massachusetts, all open 24 hours/day, that typically stock Ella. Supply may vary day by day, so it is best practice to call ahead and ensure stock. Not included on this list are hospital/clinic-based pharmacies and non-24 hours/day retail pharmacies, many of which also stock Ella.
