Plan B, also known as the "morning-after pill," is emergency contraception that can prevent pregnancy after unprotected sex or contraceptive failure. Understanding how to use it correctly is crucial for its effectiveness. This guide will walk you through the process, addressing common questions and concerns.
What is Plan B?
Plan B is a type of emergency contraception containing levonorgestrel, a hormone that works primarily by preventing ovulation. It can also interfere with fertilization and implantation, although the exact mechanism isn't fully understood. It's important to remember that Plan B is not a regular form of birth control and should not be used as a substitute.
Types of Emergency Contraception
While Plan B One-Step is a well-known brand, other emergency contraceptive options exist, including those containing ulipristal acetate (UPA) like Ella. These different types may have varying effectiveness and instructions, so always carefully read the product packaging. Consult a pharmacist or doctor if you have questions about which type is best for you.
How to Use Plan B One-Step
The instructions for Plan B One-Step are generally straightforward:
-
Take the pill as soon as possible after unprotected sex. The sooner you take it, the more effective it will be. Ideally, it should be taken within 72 hours (3 days), but the sooner the better.
-
Take only one pill. Do not take more than one pill unless explicitly instructed by a healthcare professional.
-
Follow the instructions on the packaging. Each brand may have slightly different instructions, so it’s vital to read them carefully.
-
Don't vomit. If you vomit within 2 hours of taking Plan B, contact your doctor or pharmacist; you might need to take another pill.
What to Expect After Taking Plan B
After taking Plan B, you might experience some side effects, including:
- Nausea: This is a common side effect.
- Vomiting: As mentioned, vomiting within two hours requires contacting a healthcare professional.
- Breast tenderness: Some women experience breast discomfort.
- Fatigue: Feeling tired is also possible.
- Menstrual changes: Your period may be lighter, heavier, earlier, or later than usual.
These side effects are usually mild and temporary. If you experience severe or persistent side effects, seek medical attention.
When Plan B Might Not Be Effective
While Plan B is highly effective, its efficacy decreases significantly the longer you wait to take it. Other factors can also affect its effectiveness, such as:
- Weight: Higher body weight can slightly reduce its effectiveness.
- Drug interactions: Some medications may interact with Plan B, reducing its effectiveness.
When to See a Doctor
It's essential to see a doctor if:
- You experience severe side effects.
- You have unprotected sex frequently.
- Your period is significantly late or irregular after taking Plan B.
- You suspect you might be pregnant.
Plan B vs. Regular Birth Control
Plan B is not a substitute for regular birth control. It's designed for emergency situations, and consistent use of a regular birth control method is crucial for preventing unwanted pregnancies. Talk to your doctor about the best birth control option for your needs.
