Plan B

Plan B (Levonorgestrel)

Active Ingredient: Levonorgestrel

Dosages: 1,5mg

Indications for the Medication

Plan B, commonly known as the morning-after pill, is an emergency contraceptive pill that is used in specific situations. It is important to understand the indications for this medication to ensure its proper use and effectiveness.

1. Unprotected Intercourse

The primary indication for using Plan B is in situations of unprotected intercourse. This can occur due to a variety of reasons, such as a condom slipping or breaking, missed birth control pills, or no contraceptive method being used. When unprotected intercourse happens, there is an increased risk of unintended pregnancy.

2. Contraceptive Failure

Plan B can also be used in cases of contraceptive failure. This can happen when the chosen contraceptive method, such as birth control pills or an IUD, fails to effectively prevent pregnancy. In such cases, taking Plan B as soon as possible after the failure can help reduce the chances of becoming pregnant.

3. Missed Contraceptive Methods

In situations where contraceptive methods are missed or not used correctly, Plan B can act as a backup option. This includes scenarios where birth control pills are forgotten, patches or rings are not replaced on time, or condoms are not used consistently or correctly. Taking Plan B can provide an additional layer of protection against unintended pregnancy.

4. Sexual Assault

In cases of sexual assault, Plan B can be an important tool for individuals who do not wish to become pregnant as a result of the assault. Survivors of sexual assault can take Plan B to help prevent unwanted pregnancy, although it is important to seek immediate medical attention and support after such incidents.

5. Inadequate Use of Birth Control

Plan B may also be used when individuals recognize that their chosen birth control method was not used properly. This can include scenarios where the condom was not used throughout intercourse or if the birth control pill was not taken at the right time. In situations where there is a chance of contraception failure, taking Plan B can help prevent pregnancy.

It is crucial to note that Plan B is not intended to be used as a regular form of contraception. It should only be used in emergency situations as specified above. Additionally, consulting a healthcare professional or pharmacist is recommended to discuss the appropriate use and potential side effects of Plan B.

2. How does Plan B work?

Plan B works by primarily preventing ovulation, which is the release of an egg from the ovary. It contains levonorgestrel, a synthetic hormone that is similar to the hormone progesterone, which is naturally produced by the ovaries. Levonorgestrel works by inhibiting the release of luteinizing hormone (LH), which is necessary for ovulation to occur.

In addition to preventing ovulation, Plan B also alters the cervical mucus, making it thicker and less favorable for sperm to travel through. This makes it more difficult for sperm to reach an egg if fertilization were to occur.

If fertilization has already occurred, Plan B may still be effective in preventing pregnancy by interfering with the implantation of the fertilized egg in the uterus. It can make the uterine lining less receptive to the fertilized egg, thus preventing implantation and ultimately pregnancy.

Effectiveness of Plan B

Plan B is most effective when taken as soon as possible after unprotected intercourse or contraceptive failure. It is recommended to take it within 72 hours, but it can still be effective up to 120 hours (5 days) after intercourse. However, the effectiveness decreases as time passes.

Studies have shown that Plan B can reduce the risk of pregnancy by 75-89% when taken within 72 hours. The effectiveness decreases to about 61% when taken between 72-120 hours after unprotected intercourse.

Side Effects of Plan B

Like any medication, Plan B can cause side effects. Common side effects include nausea, fatigue, headache, abdominal pain, and breast tenderness. These side effects are usually mild and go away on their own.

Rare but more serious side effects may include severe abdominal pain, persistent vomiting, severe dizziness, chest pain, or shortness of breath. If any of these symptoms occur, it is important to seek medical attention immediately.

It is worth noting that Plan B does not protect against sexually transmitted infections (STIs). It is only meant to prevent pregnancy and should not be used as a regular form of contraception.

In conclusion, Plan B is an emergency contraceptive pill that primarily works by preventing ovulation and altering the cervical mucus. It can also potentially prevent implantation of a fertilized egg if taken after fertilization has occurred. While it is effective in preventing pregnancy, it is important to remember that it does not protect against STIs and should not be used as a regular form of contraception.

Point 3: Dosage and Administration

When it comes to using Plan B, it is important to understand the correct dosage and administration guidelines. Here’s what you need to know:

Dosage:

  • The recommended dosage for Plan B is one pill, taken as soon as possible within 72 hours (3 days) after unprotected sex or contraceptive failure.
  • The sooner you take Plan B, the more effective it is at preventing pregnancy.
  • Plan B is not intended to be used as a regular method of contraception and should only be taken in emergency situations.

Administration:

  • Plan B is available over-the-counter without a prescription, and it is most effective when taken as soon as possible after unprotected sex or contraceptive failure.
  • Simply take one pill orally with water. There is no need to take additional pills after the initial dose.
  • Plan B can be taken with or without food.
  • If you vomit within two hours of taking Plan B, it is advised to consult a healthcare professional as you may need to take another dose.
  • Plan B does not protect against sexually transmitted infections (STIs), so it is important to also use barrier methods, such as condoms, to prevent STIs.

It is crucial to remember that Plan B is designed for emergency use only and should not be used as a regular contraceptive method. If you find yourself needing to use Plan B frequently, it may be worth considering a more reliable form of birth control, such as daily oral contraceptive pills or long-acting reversible contraceptives like an intrauterine device (IUD) or implant.
