Specializes in Preventive Medicine

"Up to 89%": Information about the effectiveness of the Morning-After Pill or Plan B One-Step is that the progestin/levonogestrel pills are up to 89% effective when taken within 72 hours of unprotected sex, even at time of ovulation. Some effectiveness remains up to 120 hours after. Please pursue more reliable methods of regular contraception; Morning-after pill should rarely be taken. Good wishes!
