In today’s world, navigating reproductive health can be daunting, especially with the changing landscape of laws and access to services. Fortunately, you don’t need to stress too much about emergency contraception like Plan B. While it should not replace regular birth control, it is an effective option shortly after unprotected intercourse. You can easily obtain it without a prescription, either by visiting a local pharmacy or ordering online from major retailers. Plus, you can have someone else pick it up for you if needed.
With many states limiting access to safe and legal abortions, having a reliable backup plan for any instances of unprotected sex is essential. It’s crucial to understand how Plan B works, its effects on your body, and how to use it correctly. If you have any doubts or questions, now is an excellent time to consult your healthcare provider.
How Does Plan B Function?
Plan B is a branded form of the medication levonorgestrel, which is a synthetic hormone. While Plan B is the most recognized name, other brands containing levonorgestrel are also available, often at a lower cost.
What is Levonorgestrel?
Levonorgestrel operates by releasing hormones in your body that inhibit ovulation and prevent a fertilized egg from implanting in the uterus. “Emergency contraceptives like Plan B are effective in preventing pregnancy no matter the brand,” explains Dr. Lisa Thompson, a professor at the University of California and a certified Women’s Health Care Nurse Practitioner. Essentially, it prevents the conditions necessary for pregnancy to occur, distinguishing it from abortion pills, which terminate an existing pregnancy.
When Should You Use Plan B?
Timing is critical with emergency contraceptives. Plan B is most effective when taken within the first five days (120 hours) following unprotected sex. “Plan B is 98-99% effective when taken within 72 hours,” Dr. Thompson states. It remains effective for up to five days, with an effectiveness rate of 85-90%.
What is the Cost of Plan B?
According to GoodRx, the price of brand-name Plan B ranges from $38 to $50, while generic alternatives can be found for as little as $10, depending on your location. These can all be purchased over-the-counter.
Can You Use Plan B Frequently?
Planned Parenthood informs that Plan B can be used as often as necessary. Repeated use does not diminish its effectiveness or lead to long-term health issues. However, it is not meant to be a substitute for regular contraceptive methods.
Does Plan B Influence Fertility?
There is a common misconception that Plan B can impact fertility. However, using Plan B, even multiple times, does not affect your chances of conceiving in the future. The hormones in Plan B are not harmful and are part of the natural reproductive process.
What is the Shelf Life of Plan B?
Plan B has a shelf life of approximately four years. If you wish to keep it on hand for emergencies, it’s advisable to replace it after that timeframe to ensure its effectiveness.
Is There a Weight Limit for Plan B?
While there is no strict weight limit, studies suggest that Plan B may be less effective in individuals over 165 pounds or with a BMI greater than 25. In such cases, Dr. Thompson recommends considering ELLA, a prescription-only emergency contraceptive that may offer better efficacy. It’s always best to consult with a healthcare professional for tailored advice.
Are There Side Effects from Plan B?
Some individuals may experience side effects such as nausea or headaches after taking Plan B, so it is advisable to consume it with food. Your menstrual cycle may also be slightly altered, coming earlier or later than expected. If you are already pregnant, taking Plan B will not harm you or the fetus.

Always consult with a healthcare professional for personalized guidance.
