Plan B® One-Step Pharmacists: What is Plan B® One-Step?

Consumers | Prescribers | Pharmacists

Plan B^® One-Step is the only FDA-approved single-tablet, single-dose emergency contraceptive currently available, composed of one (levonorgestrel, 1.5 mg) progestin-only tablet. When taken as directed— within 72 hours (3 days) after contraceptive failure or unprotected intercourse—approximately seven out of eight women who would have gotten pregnant will not become pregnant after taking Plan B^® One-Step. Plan B^® One-Step is more effective the sooner it’s taken, especially within the first 24 hours, so the tablet should be taken as soon as possible.

Plan B^® One-Step is different from other emergency contraceptive formulations such as the Yuzpe regimen (levonorgestrel and ethinyl estradiol) in that it contains no estrogen.

Plan B^® One-Step is available behind the counter at pharmacies and sold under the supervision of a licensed pharmacist. A prescription is needed for women under 17.

Plan B^® One-Step isn’t RU-486 (the abortion pill). Plan B^® One-Step will not affect an existing pregnancy.
Plan B^® One-Step isn’t a substitute for a routine contraception method; it should not be used that way, because it is not as effective as other methods of birth control used consistently and correctly.
