Two years after U.S. approval of the first over-the-counter birth control pill, new research shows many people who face barriers to medical care are turning to it.

The study, published Monday in JAMA Network Open, included data from 986 people ages 15 to 45 across 44 states. All had obtained the pill -- known as Opill -- either online or from a pharmacy.

Researchers found many switched from less effective birth control methods or from using no contraception at all.

There was a 31.8% increase in use among people who had previously used no birth control, and a 41% increase among those who had relied on methods like condoms or emergency contraception.
