The first birth control pill to be available without a prescription in the United States is now online.

The product called Opill can be bought on Amazon and Opill.com. Orders are expected to be filled in a day or two.

A month’s supply has a recommended price of $19.99. A three-month supply is $49.99. Some OBGYNs said online access to the pill will benefit women who live in remote areas or may not have transportation to stores that carry it.
