Plan B (generic name: levonorgestrel) is a pill that is used in the prevention of unwanted pregnancies. The recommended dosage is to take the first Plan B pill as soon as possible after the intercourse. The second Plan B pill is taken twelve hours after the first one.

There is no medical scientific data from independent studies about taking one more pill 24 hours after another intercourse. There is a probability that the pill from the first treatment would be enough to prevent the pregnancy this time. However, taking one more pill would not cause more serious side effects than it might be expected when taken properly. You might experience a change in the period or menstrual cycle, unexpected spotting, or bleeding. If any of this happens and lasts for a longer period you might want to consult your gynecologist about taking medications that would bring back your regular hormonal fluctuations.
