Can You Take Plan B More than Once in a Month?

Linda Girgis | MD

Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.

Yes, you can take Plan B more than once in a month, though it's not recommended as routine birth control. The FDA states there are no safety concerns with multiple uses, but frequent use may cause irregular bleeding and is less reliable than regular contraceptive methods. Plan B is 95% effective when taken within 24 hours but drops to 61% effectiveness after 72 hours. Taking it multiple times can disrupt your menstrual cycle for several months. If you find yourself needing emergency contraception repeatedly, consider discussing long-term birth control options with your healthcare provider for better protection and fewer side effects.
