Can You Take Plan B While on Birth Control?

Yes, you can safely take Plan B emergency contraception while on regular birth control. Taking Plan B with hormonal birth control like pills, patches, or rings does not cause dangerous interactions or reduce the effectiveness of either medication. Plan B contains levonorgestrel, a synthetic hormone that temporarily prevents ovulation, while your regular birth control maintains consistent hormone levels to prevent pregnancy. If you're on birth control and took it correctly, Plan B is typically unnecessary since your regular contraception is already 91-99% effective. However, Plan B can provide extra protection if you missed pills, experienced vomiting, or had other factors that might reduce your birth control's effectiveness.
