Advance provision of abortion medications is the prescription of mifepristone and misoprostol before pregnancy occurs. Physicians in the US do not routinely engage in advance provision, yet there is considerable interest among US populations. Following recent abortion bans, advance provision could allow people to have abortion medications immediately available if needed. Using data from Aid Access, an online telemedicine service that has offered advance provision since September 2021, we examined trends in the demand and characteristics and motivations of requestors.
