What are the side effects of emergency contraceptives?
There are some minor side effects of emergency contraceptives. The emergency contraceptives Plan B One-Step®
and Next Choice® are
made from levonorgestrel - a common ingredient of many birth control pills. Some of the side
effects are similar to those of regular birth control pills such as: nausea, abdominal pain,
tiredness, headache, dizziness, and breast tenderness.
Some women may experience changes in their menstrual cycle after taking Plan B One-Step® or Next Choice® - spotting or bleeding before their next expected cycle, heavier or lighter bleeding - or they may start their period earlier or later than usual. Most women should expect to get their period at their expected time or within a week of their expected time. However, if your period is more than a week late, you may be pregnant and should contact your healthcare provider.
Important Note: If you are taking Plan B One-Step® or Next Choice® and vomit within 1 hour of taking either medication, then call your healthcare provider immediately to determine whether you need to repeat the dose.
Remember that Plan B One-Step® or Next Choice® is not meant to be a routine method of birth control. In addition, neither medication protects against sexually transmitted diseases, including HIV/AIDS.
