If you opt to take the emergency contraception pill containing levonorgestrel, there are several options to choose from. According to Planned Parenthood, these options include Plan B One-Step, Take Action, My Way, Option 2, Preventeza, AfterPill, My Choice, Aftera, and EContra. Perhaps the most common options you'll spot on drugstore shelves are the Plan B One-Step and Aftera. Many are likely to opt for Aftera, as it costs $39.99 per pill, while the Plan B One-Step costs $49.99 per pill (via CVS).
While Aftera and Plan B One-Step may differ in price, they each contain the same active and inactive ingredients. Plan B One-Step and Aftera both contain 1.5 milligrams of levonorgestrel and colloidal silicon dioxide, corn starch, lactose monohydrate, magnesium stearate, potato starch, and talc, according to the Food and Drug Administration and the U.S. National Library of Medicine. So, the only real difference between the two emergency contraception pills is their price.
Emergency contraception pills like Plan B and Aftera are ideal for most women as they don't require a prescription from a doctor and can be purchased over the counter. It is important to note that, according to Planned Parenthood, emergency contraceptive pills like Plan B and Aftera might not work for those who weigh 155 pounds or more or those who take the pill three days or more after engaging in unprotected sex. The sooner you take the emergency contraception pill, the better.
