Plan B, also known as the morning-after pill, is an emergency contraceptive pill used to prevent pregnancy after unprotected sex. It contains the hormone levonorgestrel and is most effective when taken as soon as possible after unprotected sex.

Plan B can reduce the risk of pregnancy by up to 87% if taken within 72 hours after unprotected sex. However, its effectiveness decreases as time passes, so it’s recommended to take it as soon as possible. It is important to note that Plan B is less effective than regular contraception and does not protect against sexually transmitted diseases.

Plan B Effectiveness Timeframe
Plan B is most effective when taken as soon as possible after unprotected sex. The effectiveness of the pill decreases with time, so it is essential to act quickly. Research has shown that Plan B can reduce the risk of pregnancy by up to 87% if taken within 72 hours after unprotected sex.

Using condoms or other forms of contraception in addition to Plan B is highly recommended to prevent unintended pregnancies.

Side Effects of Levonorgestrel
Potential side effects of levonorgestrel, the active ingredient in Plan B, may include vomiting, unexpected bleeding, and changes in menstrual cycle. It’s important to note that not everyone experiences these side effects, and they are generally temporary and resolve on their own. If you have concerns or persistent side effects, it’s always best to consult with a healthcare professional.
Some individuals may experience nausea or vomiting after taking Plan B. If vomiting occurs within two hours of taking the pill, it is recommended to speak with a healthcare provider, as another dose may be necessary. However, even if vomiting does not occur, it’s common to have temporary changes in the menstrual cycle, such as earlier or later periods or irregular bleeding. These changes typically resolve within a few cycles.
Unexpected bleeding is a common side effect of levonorgestrel emergency contraception. It may occur before your next expected period or in between periods. The amount and duration of bleeding can vary from person to person. If you experience heavy or prolonged bleeding, or if you have concerns about the bleeding, it’s advisable to seek medical advice.
While side effects are possible with any medication, it’s important to remember that levonorgestrel is a safe and effective form of emergency contraception. Plan B’s benefits in preventing unintended pregnancy greatly outweigh the potential risks associated with temporary side effects.

Plan B, also known as the morning-after pill, is designed to be used as an emergency contraceptive option after unprotected sex or contraceptive failure. It is not intended to replace regular contraception methods, such as condoms or hormonal birth control.
Using Plan B as your primary method of contraception is not recommended, as it is less effective than regular contraception in preventing pregnancy.

Therefore, it is crucial to discuss with your healthcare provider and explore more reliable and sustainable contraceptive options for everyday use.
While Plan B is easily accessible over the counter at drugstores without a prescription or age verification, it is essential to remember that it does not protect against sexually transmitted diseases (STDs). It is crucial to prioritize your sexual health and utilize barrier methods, such as condoms, to reduce the risk of STD transmission.
To ensure the most effective protection against unwanted pregnancies and STDs, it is advisable to use Plan B as an emergency contraceptive only. Incorporating a reliable form of birth control into your regular routine will help to prevent unintended pregnancies and provide ongoing protection. Consult with your healthcare provider to find the best contraceptive method that suits your needs and preferences.

Plan B Does Not Protect Against STDs
It is essential to remember that Plan B, also known as the morning-after pill, does not protect against sexually transmitted diseases (STDs). While Plan B is an effective emergency contraceptive pill used to prevent pregnancy after unprotected sex, it does not provide any protection against STDs. This is an important distinction to keep in mind when considering the use of Plan B as a form of contraception.
Plan B contains the hormone levonorgestrel, which helps prevent pregnancy by stopping the release of an egg from the ovary and may also prevent sperm from fertilizing the egg. However, it does not offer any defense against STDs such as chlamydia, gonorrhea, or HIV. If there is a risk of exposure to STDs, it is crucial to use additional methods of protection, such as condoms, to reduce the risk of infection.

When using emergency contraception like Plan B, it is essential to prioritize your sexual health and take necessary precautions. Utilizing barrier methods, such as condoms, can help reduce the risk of both pregnancy and STD transmission. It is also advisable to get tested for STDs regularly, especially if you have been involved in unprotected sexual encounters.
| Common STDs | Transmission | Prevention |
|---|---|---|
| Chlamydia | Sexual contact with an infected individual | Condom use, regular testing |
| Gonorrhea | Sexual contact with an infected individual | Condom use, regular testing |
| HIV/AIDS | Sexual contact, sharing needles | Condom use, abstinence, regular testing |
