What is emergency contraception (also known as “the morning-after pill”)?

  • Emergency contraception (EC) prevents pregnancy. EC will not disrupt an existing pregnancy.
  • EC pills that contain the progestin hormone levonorgestrel (LNG) are sold as Plan B One-Step®, Take Action™, My Way™, Aftera®, and others. One-pill LNG EC products are available over-the-counter (OTC) without age restrictions.
  • EC pills containing ulipristal acetate are sold under the brand name ella® and are prescription only.
  • EC pills work best if taken as soon as possible after unprotected sex but may work up to 5 days after.
  • EC is safe for women of all ages to use.

What are the restrictions for purchasing EC over-the-counter? Do customers need to show ID?

  • There are no age or point-of-sale restrictions on the OTC purchase of 1.5-mg LNG EC products (Plan B One-Step® and generic equivalents).
  • Ulipristal acetate (ella®) is available by prescription only.
  • Any woman or man of any age can purchase LNG EC products without needing to show ID.
  • There is no limit on the number of packages that a person can purchase.
  • A woman can get a prescription for LNG EC if she needs that for insurance reimbursement.
