Aftera and Plan B have similar active ingredients, but Plan B’s effectiveness is better supported by clinical studies.
Understanding Emergency Contraception: Aftera vs. Plan B
Emergency contraception pills (ECPs) are crucial options for preventing pregnancy after unprotected sex or contraceptive failure. Among the widely known brands, Plan B One-Step has long been a trusted name in the United States, while Aftera is a newer alternative gaining popularity due to its affordability and accessibility. Both claim to provide emergency contraception using levonorgestrel, but does Aftera work as well as Plan B? This question is vital for anyone considering their options in a time-sensitive situation.
The Active Ingredient: Levonorgestrel
Both Aftera and Plan B contain levonorgestrel, a synthetic progestin hormone. Levonorgestrel works primarily by preventing ovulation—the release of an egg from the ovary. If ovulation is delayed or prevented after unprotected intercourse, fertilization cannot occur, reducing the chance of pregnancy.
Despite sharing this active ingredient, the formulation and dosage can vary slightly between brands. Typically, both Aftera and Plan B One-Step contain 1.5 mg of levonorgestrel in a single-dose pill.
How Do These Pills Work?
Levonorgestrel-based emergency contraceptives function mainly by:
- Delaying or inhibiting ovulation: This stops eggs from being released.
- Thickening cervical mucus: This makes it harder for sperm to reach any egg that might be present.
- Altering the uterine lining: Though this effect is less significant, it may reduce the likelihood of implantation.
Neither pill will terminate an existing pregnancy; they are designed strictly to prevent pregnancy before it occurs.
Effectiveness Comparison: Does Aftera Work As Well As Plan B?
Clinical data on Plan B’s effectiveness is extensive due to its longer presence on the market and multiple studies conducted worldwide. Aftera, being relatively new and less studied in clinical trials, has less publicly available data. However, since both contain 1.5 mg levonorgestrel as a single dose, their theoretical effectiveness should be similar.
Plan B Effectiveness Statistics
Plan B One-Step has been shown to reduce the risk of pregnancy by approximately 89% when taken within 72 hours after unprotected sex. Its effectiveness decreases as time passes but remains somewhat effective up to 120 hours (5 days), though less so.
Aftera’s Effectiveness Insights
Aftera markets itself as a generic equivalent with the same active ingredient and dosage as Plan B. While specific large-scale clinical trials on Aftera are limited, regulatory authorities such as the FDA require generic medications to demonstrate bioequivalence—meaning Aftera must deliver levonorgestrel into the bloodstream at similar levels within a comparable timeframe.
This bioequivalence suggests that Aftera should work similarly to Plan B in preventing pregnancy if taken correctly within the recommended time frame.
Timing Is Everything: How Soon Should You Take Emergency Contraception?
Both Aftera and Plan B are most effective when taken as soon as possible after unprotected sex. The sooner you take them, the better your chances of preventing pregnancy.
The general window for levonorgestrel-based ECPs is up to 72 hours (3 days). Some studies suggest minor efficacy up to 120 hours (5 days), but this is not guaranteed and effectiveness declines sharply with time.
If more than five days have passed or if you are already ovulating or pregnant, these pills will not be effective.
The Role of Ovulation Timing
Emergency contraception works by delaying ovulation. If you have already ovulated before taking the pill, its ability to prevent pregnancy diminishes dramatically because fertilization could already occur.
Tracking your menstrual cycle or using ovulation predictor kits can help estimate your fertile window but should not delay taking emergency contraception if needed urgently.
Side Effects and Safety Profiles: Aftera vs. Plan B
Both medications share similar side effect profiles due to their identical active ingredient:
- Nausea and vomiting: Mild nausea is common; vomiting shortly after taking the pill may reduce effectiveness.
- Dizziness: Some users report lightheadedness.
- Fatigue: Temporary tiredness can occur.
- Headache:
- Breast tenderness:
- Changes in menstrual bleeding: Early or delayed periods are possible.
Both pills are considered safe for most women; however, they should not be used as regular contraception methods due to lower effectiveness compared with daily birth control methods.
A Closer Look: Price and Accessibility Differences
One reason consumers consider alternatives like Aftera is cost savings. Plan B One-Step typically costs between $35-$50 per pill at retail pharmacies in the U.S., whereas Aftera can be found online or at some pharmacies for roughly half that price—around $15-$25 per dose.
Availability also varies:
- Plan B One-Step: Widely available over-the-counter without age restrictions in many countries including the U.S., making it easy to find at pharmacies and drugstores.
- Aftera: Available online through various vendors; may not be stocked in all physical stores yet but gaining traction due to affordability.
Price can influence access significantly for some users who might delay treatment waiting for affordable options—a critical factor since timing impacts efficacy.
Dosing Instructions: Ensuring Maximum Effectiveness
Both pills require taking one tablet containing 1.5 mg levonorgestrel orally as soon as possible within 72 hours following unprotected intercourse.
It’s important not to split doses or take multiple pills unless directed by a healthcare provider because increasing dosage does not improve efficacy but may increase side effects.
If vomiting occurs within two hours of taking either pill, consult a healthcare professional about repeating the dose since absorption could be compromised.

Misinformation and Myths Surrounding Emergency Contraceptives Like Aftera and Plan B
Many myths surround emergency contraception that can cause confusion or hesitation:
- “They cause abortion”: This isn’t true; these pills prevent pregnancy before implantation occurs.
- “They cause infertility”: No evidence supports this claim; fertility returns immediately after use.
- “They work like regular birth control”: ECPs are less effective than daily contraceptives and shouldn’t replace them.
- “They have dangerous side effects”: The side effects are generally mild and temporary.
- “You can use them repeatedly without issues”: ECPs aren’t intended for frequent use; consult a doctor about ongoing contraception options.
Clearing these misconceptions helps individuals make informed decisions quickly during emergencies without unnecessary fear or delay.
