What is the US law for the morning after pill?

In the United States, the morning-after pill, which is an emergency contraceptive, can be obtained without a prescription for individuals of all ages. Two primary types, Plan B One-Step and Ella, are available over-the-counter at pharmacies. The pills should ideally be taken within 72 to 120 hours after unprotected intercourse to effectively prevent pregnancy. However, access and availability may vary by state and individual pharmacy policies.
