There is no minimum age to buy the morning-after pill over the counter in the United States. Since June 20, 2013, the FDA has allowed anyone to purchase levonorgestrel emergency contraception — Plan B One-Step and its generics — without a prescription, without an ID, and without any age check.1U.S. Food and Drug Administration. Plan B One-Step 1.5 mg Levonorgestrel Information
No Age Limit, No ID, No Prescription
The rule applies to Plan B One-Step and to every generic version of levonorgestrel emergency contraception, including My Way, Take Action, and Aftera. These products sit on open store shelves in the family planning aisle, not behind the pharmacy counter. The cashier should not ask for identification or proof of age, and the rule is not limited by gender. A friend, partner, or parent can buy the pill for you.
If a store clerk or pharmacist tells you otherwise, they’re wrong about federal law. The 2013 FDA decision removed every prior age cutoff.
One Type Still Requires a Prescription
The age-free rule covers levonorgestrel pills only. Ella (ulipristal acetate) is a different emergency contraceptive and still requires a prescription at any age.2U.S. Food and Drug Administration. FDA Label – ella (Ulipristal Acetate) It works longer than Plan B — up to 120 hours (five days) after unprotected sex — and holds its effectiveness more steadily across that window.3U.S. Food and Drug Administration. FDA Label – ella (Ulipristal Acetate)
Getting ella means seeing a doctor, nurse practitioner, or physician assistant. Telehealth platforms have made this much faster; several offer online consultations that send a prescription to your local pharmacy within hours, and some arrange overnight delivery.
Timing Matters More Than Age
Speed is the single biggest factor in whether the pill works. Levonorgestrel is roughly 95 percent effective when taken within 24 hours of unprotected sex, and drops to about 89 percent by the 72-hour mark. After 72 hours the window is closing fast. If you’re weighing whether to take it, take it now.
Levonorgestrel works by temporarily delaying ovulation so an egg isn’t released and can’t be fertilized. The FDA’s 2022 label update states directly that Plan B One-Step “will not work if a person is already pregnant” and “does not terminate a pregnancy.”1U.S. Food and Drug Administration.

Weight can also affect how well levonorgestrel works. Research suggests it becomes less effective for people who weigh more than 165 pounds; ella works better in that range, though its own effectiveness may decline above 195 pounds.
Side effects tend to be mild and short: headache, nausea, dizziness, breast tenderness. Your next period may come a few days early or late, or be heavier or lighter than usual.
Where to Buy It
Levonorgestrel pills are stocked at CVS, Walgreens, Rite Aid, Walmart, Target, and many grocery and convenience stores. Look in the family planning or reproductive health aisle. If you don’t see it, ask — some stores keep it in a locked case on the shelf, which still doesn’t require ID to unlock.
College students often have a closer option. Emergency contraception vending machines now operate on more than 140 campuses across roughly 40 states, and prices there tend to run lower than at retail pharmacies, often between $7 and $15 for generics.
Online ordering works better as preparation than as an emergency response. Delivery time is the problem when every hour matters.
What It Costs and Whether Insurance Covers It
Brand-name Plan B One-Step usually runs $40 to $50 at retail. Generics are considerably cheaper, often $10 to $25. Ella generally costs $40 to $60, plus any telehealth consultation fee.
Under the Affordable Care Act, most health plans must cover FDA-approved contraception, including emergency contraception, without cost sharing when it’s obtained with a prescription.4Health Resources and Services Administration. Women’s Preventive Services Guidelines The catch for the OTC pill: buying it off the shelf without a prescription usually means paying out of pocket. Asking your doctor to write a prescription for a pill that’s also available OTC triggers the ACA coverage requirement.
A proposed federal rule that would have required insurers to cover OTC contraception without a prescription was withdrawn in January 2025.5Federal Register. Enhancing Coverage of Preventive Services Under the Affordable Care Act
If you have a Health Savings Account or Flexible Spending Account, emergency contraception is a reimbursable expense even without a prescription. The CARES Act removed the prescription requirement for OTC products purchased through those accounts.6Internal Revenue Service. IRS Outlines Changes to Health Care Spending Available Under CARES Act
State Rules That Can Slow You Down
Emergency contraception is legal in every state, but a few state-level rules affect access in practice.
A small number of states have conscience clauses that allow a pharmacist to refuse to dispense contraception on moral or religious grounds. Some require a referral to another pharmacist or nearby pharmacy; others don’t. If you’re refused, asking for a different pharmacist at the same store usually resolves it, and you can file a complaint with your state board of pharmacy.
A growing number of states let pharmacists prescribe certain contraceptives directly, which can make ella available without a separate doctor visit.
At least 17 states and the District of Columbia require hospital emergency departments to dispense emergency contraception to sexual assault survivors on request. Other states require hospitals to at least provide information about it.
