Best Emergency Contraceptive Pills: Aftera, AfterPill & Plan B One-Step

What Are Emergency Contraceptive Pills?

Emergency contraceptive pills are medications used to reduce the chance of pregnancy after unprotected sex or birth-control failure. They may be considered when no contraception was used, a condom broke or slipped, regular birth-control pills were missed, or another contraceptive method was used incorrectly.

Aftera, AfterPill and Plan B One-Step are single-dose emergency contraceptive pills containing 1.5 milligrams of levonorgestrel. Levonorgestrel is a synthetic form of the hormone progestin that has been used in hormonal contraception for many years.

These products are commonly called morning-after pills, but they do not have to be taken the following morning. They should be taken as soon as possible after unprotected sex or contraceptive failure. Product labeling recommends taking levonorgestrel emergency contraception within 72 hours, or three days.

Emergency contraceptive pills are intended for backup contraception rather than routine birth control. They do not end an established pregnancy, do not affect an implanted pregnancy and do not protect against HIV or other sexually transmitted infections.

Quick Facts

• Product Type: Single-dose emergency contraceptive pill
• Category: Over-the-counter backup contraception
• Active Ingredient: Levonorgestrel 1.5 mg
• Best For: Reducing pregnancy risk after unprotected sex or contraceptive failure

• Number of Tablets: One tablet per treatment
• Prescription Required: No
• Suitable for Regular Birth Control: No
• Protects Against STIs: No

Why Are Emergency Contraceptive Pills Popular?

Levonorgestrel emergency contraceptive pills are popular because they provide an accessible backup option when regular contraception was not used or did not work as intended. They are available without a prescription and require only one tablet.

Emergency contraceptive pills may help:

• Reduce pregnancy risk after unprotected sex
• Provide backup after a condom breaks or slips
• Provide backup after missed birth-control pills
• Offer an over-the-counter contraceptive option
• Allow treatment with one oral tablet
• Provide an option that can be purchased in advance

Consumers also appreciate having several generic and branded choices. Aftera, AfterPill and Plan B One-Step contain the same type and amount of active ingredient, allowing buyers to compare price, availability and brand preference.

How Do Emergency Contraceptive Pills Work?

Levonorgestrel emergency contraception primarily works by delaying or preventing ovulation. Ovulation occurs when an ovary releases an egg. When no egg is released, sperm cannot fertilize it and begin a pregnancy.

The medication is more likely to work when taken before ovulation. It may be less effective after ovulation has already occurred, which is one reason taking it promptly is important.

Levonorgestrel emergency contraception is not an abortion pill. It does not terminate an established pregnancy and will not work when someone is already pregnant.

Important Active Ingredient

• Levonorgestrel 1.5 mg: A synthetic progestin that temporarily delays or prevents ovulation, helping reduce the likelihood of pregnancy.

Because Aftera, AfterPill and Plan B One-Step contain the same active ingredient and dose, brand name and package design are not the main factors affecting results. Taking the medication promptly and following the package directions are more important.

Scientific Evidence

Levonorgestrel has been widely studied and used as emergency contraception. Evidence supports taking a single 1.5-milligram dose as soon as possible following unprotected sex or contraceptive failure.

Levonorgestrel emergency contraception can significantly reduce the chance of pregnancy when taken correctly. However, no emergency contraceptive pill is completely effective, and effectiveness generally decreases as more time passes.

Research indicates that levonorgestrel works mainly by delaying or preventing ovulation. It does not interfere with an implanted pregnancy and should not be confused with medications used for abortion.

Some evidence suggests that levonorgestrel emergency contraceptive pills may be less effective at higher body weights or body mass indexes. People concerned about effectiveness can speak with a pharmacist or healthcare professional about other emergency contraceptive options, including prescription ulipristal acetate or an emergency intrauterine device.

Potential Benefits

• May reduce pregnancy risk after unprotected sex
• May provide backup after contraceptive failure
• May be purchased without a prescription
• May be purchased in advance for unexpected situations
• Requires only one tablet
• Does not affect long-term fertility
• Does not terminate an existing pregnancy
• Provides several branded and generic choices

Why Choose a Levonorgestrel Emergency Contraceptive?

Someone may choose levonorgestrel emergency contraception because it is widely available, easy to take and sold without a prescription. Generic versions offer the same active ingredient and strength as Plan B One-Step, often at a lower price.

People choose these products because they:

• Contain an established emergency contraceptive ingredient
• Provide a complete dose in one tablet
• Are available over the counter
• Can be stored in advance until the expiration date
• Are easy to take discreetly
• Offer different price and packaging options

Who May Benefit?

Emergency contraception may be useful for someone who:

• Had sex without contraception
• Experienced a broken or slipped condom
• Missed one or more regular birth-control pills
• Used a contraceptive method incorrectly
• Was late receiving a scheduled contraceptive method
• Needs backup after contraceptive failure

How to Use Emergency Contraception

1. Take one tablet by mouth as soon as possible after unprotected sex or birth-control failure.
2. Take the tablet within 72 hours, or three days.
3. Swallow the tablet with water.
4. It may generally be taken with or without food.
5. If vomiting occurs within two hours, contact a pharmacist or healthcare professional because another dose may be needed.
6. Begin or resume regular contraception according to its instructions.
7. Use condoms or avoid sexual intercourse for seven days after beginning or restarting regular hormonal contraception.
8. Take a pregnancy test if the next period is more than one week late or expected bleeding does not occur within approximately three weeks.

Emergency contraception only addresses sexual activity that occurred before the tablet was taken. It does not provide continuing pregnancy protection for unprotected sex later in the same menstrual cycle.

Always follow the manufacturer's directions.

Possible Side Effects

Most levonorgestrel emergency contraceptive pills are generally well tolerated.

Possible side effects may include:

• Nausea
• Headache
• Dizziness
• Tiredness
• Lower abdominal discomfort
• Breast tenderness
• Vomiting
• Spotting between periods
• Earlier or later menstrual bleeding
• Heavier or lighter menstrual bleeding

The next menstrual period may begin several days earlier or later than expected. Seek medical care for severe or persistent lower abdominal pain, especially three to five weeks after taking emergency contraception, because this requires evaluation for a possible ectopic pregnancy.

Discontinue use and seek medical advice if a serious reaction develops.

Who Should Consult a Healthcare Professional?

Speak with a pharmacist or healthcare professional if you:

• Know or suspect that you are already pregnant
• Have unexplained vaginal bleeding
• Experience severe or persistent abdominal pain
• Take seizure medications, rifampin, St. John’s wort or other medicines that may interact with levonorgestrel
• Have questions about whether body weight may affect effectiveness
• Vomit within two hours after taking the tablet
• Have a period that is more than one week late
• Need emergency contraception more than 72 hours after unprotected sex

Do not take levonorgestrel emergency contraception if you have previously experienced a serious allergic reaction to levonorgestrel or another ingredient listed on the package.

Does emergency contraception really work?

Take the tablet as soon as possible after unprotected sex or contraceptive failure. Product labeling recommends use within 72 hours, and earlier treatment generally works better.

What happens if I vomit after taking it?

Contact a pharmacist or healthcare professional if you vomit within two hours. Another dose may be necessary, but seek professional guidance before repeating it.

Can I use emergency contraception as regular birth control?

Emergency contraception is intended for backup use. Regular contraceptive methods are generally more effective and practical for ongoing pregnancy prevention.

Can emergency contraception be used more than once?

Levonorgestrel emergency contraception may be used again when needed. However, frequent need may be a reason to discuss a dependable ongoing contraceptive method with a healthcare professional.

Contact a pharmacist or healthcare professional promptly to discuss whether another emergency contraceptive option may be more appropriate.

Can medications interfere with levonorgestrel?

Some medicines and herbal products may reduce levonorgestrel levels. These may include certain seizure medicines, rifampin and St. John’s wort. Ask a pharmacist or healthcare professional about possible interactions.

What should I do if more than 72 hours have passed?

Contact a healthcare professional or reproductive-health provider promptly. Other emergency contraceptive options may still be available for up to five days after unprotected sex.

When should I seek urgent medical attention?

Seek prompt medical care for severe lower abdominal pain, fainting, unusually heavy bleeding, signs of an allergic reaction or a positive pregnancy test accompanied by pain.

Final Thoughts

Aftera, AfterPill and Plan B One-Step are single-dose levonorgestrel emergency contraceptives intended to reduce pregnancy risk after unprotected sex or birth-control failure. All three featured products contain the same 1.5-milligram active dose, so their primary differences involve price, packaging, brand recognition, inactive ingredients and availability.

Aftera is our Best Overall selection, AfterPill is our Best Budget choice and Plan B One-Step is our Most Popular option. However, the best choice in a time-sensitive situation is usually a properly sealed, unexpired levonorgestrel product that can be obtained and taken immediately.

Emergency contraceptive pills do not replace regular birth control, do not protect against sexually transmitted infections and do not terminate an existing pregnancy. Speak with a pharmacist or healthcare professional if more than 72 hours have passed, interacting medications may be involved, your period is late or you need help selecting the most appropriate emergency contraceptive.
