Plan B is safe to take multiple times, with no long-term fertility risks
Emergency contraception is most effective when taken as soon as possible
Frequent use may cause temporary menstrual cycle changes
Birth control alternatives might be more consistent for regular protection
Emergency contraception provides a critical safety net for unexpected reproductive health situations. Plan B, a popular emergency contraception method, helps prevent unintended pregnancy when primary birth control methods fail. Understanding its safe usage can help you make informed decisions about your reproductive health.
Emergency contraception works by temporarily delaying ovulation, preventing potential fertilization. While many people worry about repeated use, medical research shows that Plan B remains safe and effective for multiple applications.
Most healthcare professionals agree that you can take Plan B as needed. Birth control options like Plan B do not have a strict annual limit. However, frequent use might indicate a need to explore more consistent contraception methods.

While Plan B is generally safe, you might experience temporary side effects such as:
Menstrual cycle changes
Mild nausea
Headaches
Breast tenderness

Emergency contraception can be more expensive than regular birth control. A single Plan B dose ranges from $11 to $50, which can become costly with frequent use. Birth control alternatives might provide more consistent and affordable protection.
If you find yourself repeatedly using emergency contraception, it's wise to discuss more reliable birth control options with a healthcare professional.
