What Is A Plan B? It’s an emergency contraception pill that can help prevent pregnancy after unprotected sex. At WHAT.EDU.VN, we understand you need clear and quick answers, so we’ve compiled everything you need to know. Discover backup plans, reproductive options, and immediate solutions with us.
1. Understanding Plan B: The Basics
Plan B, also known as the morning-after pill, is a type of emergency contraception that can be taken to prevent pregnancy after unprotected sex or if your regular birth control method fails.
1.1 What is Plan B and How Does it Work?
Plan B contains levonorgestrel, a synthetic progestin. It works primarily by delaying ovulation, preventing the release of an egg from the ovary. If ovulation has already occurred, Plan B may also prevent fertilization of the egg or implantation in the uterus.
1.2 When Should You Take Plan B?
Plan B is most effective when taken as soon as possible after unprotected sex. It can be taken up to 72 hours (3 days) after, but its effectiveness decreases with each passing day. Some studies suggest it might still have some effect up to 120 hours (5 days) after, but other options like the ella morning-after pill or a copper IUD might be more effective at that point.
1.3 Is Plan B the Same as an Abortion Pill?
No, Plan B is not an abortion pill. It prevents pregnancy from occurring. An abortion pill, on the other hand, terminates an existing pregnancy. Plan B will not work if you are already pregnant.
2. Effectiveness of Plan B
Plan B is a reliable option for emergency contraception, but it’s important to understand its effectiveness rates and factors that can influence them.
2.1 How Effective is Plan B?
When taken within 72 hours of unprotected sex, Plan B can reduce the risk of pregnancy by 75-89%. The sooner you take it, the more effective it is.
2.2 Factors Affecting Effectiveness
Several factors can affect how well Plan B works:
- Time since unprotected sex: The sooner you take Plan B, the more effective it is.
- Weight: Plan B may be less effective for women who weigh over 165 pounds (75 kg). In such cases, other emergency contraception options like ella or a copper IUD might be more suitable.
- Medications: Certain medications, such as some antibiotics, antifungals, HIV medications, anti-seizure medications, and St. John’s Wort, can reduce the effectiveness of Plan B.
2.3 Comparing Plan B to Other Emergency Contraception Methods
Plan B is one of several emergency contraception options available. Here’s a quick comparison:
| Method | Effectiveness | Window of Time | Availability | Notes |
|---|---|---|---|---|
| Plan B | 75-89% within 72 hours | Up to 72 hours | Over-the-counter | Less effective for women over 165 lbs. |
| Ella | Up to 85% within 120 hours | Up to 120 hours | Prescription required | Maintains effectiveness for women with higher BMI. |
| Copper IUD | Over 99% | Up to 120 hours | Requires insertion by a healthcare provider | Most effective emergency contraception method; can also be used as ongoing birth control. |
For more detailed information, consult with a healthcare provider or visit WHAT.EDU.VN for reliable resources.
3. How to Use Plan B
Using Plan B is straightforward, but it’s crucial to follow the instructions carefully.
3.1 Dosage and Administration
Plan B is typically a single-dose pill. Simply swallow the tablet as soon as possible after unprotected sex. Read the instructions that come in the package for more information.
3.2 What to Do If You Vomit
If you vomit within 2 hours of taking Plan B, the medication may not be absorbed properly. You will need to take another dose as soon as possible. Contact your healthcare provider or pharmacist for guidance.
3.3 When to Expect Your Next Period
After taking Plan B, your next period may come earlier, later, or be different than usual. It’s normal to experience some spotting or changes in flow. If you don’t get your period within 3 weeks of taking Plan B, take a pregnancy test to rule out pregnancy.

4. Side Effects of Plan B
While Plan B is safe for most women, it can cause some side effects. Understanding these potential effects can help you be prepared.
4.1 Common Side Effects
The most common side effects of Plan B include:
- Nausea
- Vomiting
- Headache
- Dizziness
- Breast tenderness
- Changes in your period
These side effects are usually mild and temporary, resolving within a few days.
4.2 Serious Side Effects
Serious side effects from Plan B are rare. However, if you experience severe abdominal pain, persistent vomiting, or signs of an allergic reaction (such as rash, itching, or difficulty breathing), seek immediate medical attention.
4.3 Managing Side Effects
To manage common side effects, you can try:
- Taking Plan B with food to reduce nausea.
- Using over-the-counter pain relievers for headaches or breast tenderness.

5. Where to Get Plan B
Plan B is readily available at most pharmacies and drugstores.
5.1 Over-the-Counter Availability
In the United States, Plan B is available over the counter without a prescription for people of all ages and genders. You can find it at drugstores, pharmacies, and some convenience stores.
5.2 Cost of Plan B
The cost of Plan B can vary depending on the brand and location. Generic versions are typically less expensive than brand-name Plan B. You may also be able to get Plan B for free or at a reduced cost from family planning clinics or health departments.
5.3 Online Options
You can also order Plan B online, but be sure to use a reputable source to ensure you are getting a genuine product. Keep in mind that shipping times may vary, so it’s best to have Plan B on hand before you need it.
6. Plan B and Your Health
Plan B is a safe option for emergency contraception, but it’s essential to consider its impact on your overall health.
6.1 Impact on Future Fertility
Plan B does not affect your future fertility. It prevents pregnancy from occurring but does not have any long-term effects on your ability to get pregnant in the future.
6.2 Interactions with Medications
As mentioned earlier, certain medications can reduce the effectiveness of Plan B. It’s important to inform your healthcare provider about any medications or supplements you are taking to ensure Plan B will work effectively.
6.3 When to See a Doctor
You should see a doctor if:
- You don’t get your period within 3 weeks of taking Plan B.
- You experience severe abdominal pain.
- You have signs of an allergic reaction.
- You have concerns or questions about Plan B.
7. Common Misconceptions About Plan B
It’s crucial to dispel common misconceptions about Plan B to ensure informed decision-making.
7.1 Plan B Causes Abortions
As mentioned earlier, Plan B is not an abortion pill. It prevents pregnancy from occurring and will not terminate an existing pregnancy.
7.2 Plan B is 100% Effective
Plan B is not 100% effective. Its effectiveness depends on how quickly you take it after unprotected sex. The sooner you take it, the better.
7.3 You Can Use Plan B as Regular Birth Control
Plan B is intended for emergency use only and should not be used as a regular form of birth control. Regular birth control methods, such as birth control pills, IUDs, and condoms, are more effective at preventing pregnancy.
8. Emergency Contraception: Beyond Plan B
Plan B is just one option for emergency contraception. It’s helpful to know about other available methods.
8.1 Ella (Ulipristal Acetate)
Ella is another type of morning-after pill that requires a prescription. It can be taken up to 120 hours (5 days) after unprotected sex and may be more effective than Plan B for women with a higher BMI.
8.2 Copper IUD
A copper IUD (intrauterine device) can be inserted up to 120 hours (5 days) after unprotected sex to prevent pregnancy. It is the most effective form of emergency contraception and can also be used as ongoing birth control.
8.3 Choosing the Right Method
The best emergency contraception method for you depends on your individual circumstances. Consider factors such as your weight, how long it has been since unprotected sex, and whether you want ongoing birth control. Consult with a healthcare provider for personalized advice.
9. Preventing Unplanned Pregnancy
Emergency contraception is a backup plan, but the best approach is to prevent unplanned pregnancy in the first place.
9.1 Regular Birth Control Methods
There are many effective methods of regular birth control, including:
- Birth control pills
- IUDs
- Implants
- Shots
- Rings
- Condoms
Talk to your healthcare provider to find the best method for you.
9.2 Importance of Safe Sex Practices
Always practice safe sex by using condoms to protect against both pregnancy and sexually transmitted infections (STIs). Regular STI testing is also important for maintaining your sexual health.
9.3 Resources for Sexual Health Education
There are many resources available for sexual health education, including:
- Planned Parenthood
- Local health departments
- Online resources like WHAT.EDU.VN
