Plan B® is approved by the FDA for use as an emergency contraceptive. And it contains the same birth control hormone that healthcare professionals have been prescribing for more than 35 years. When used as directed, Plan B® is safe for women. Plan B® has no serious or lasting medical side effects. Some women will experience non-serious side effects, such as nausea, stomach pain, headache, dizziness, or breast tenderness. These are similar to the side effects of regular birth control pills. Some women have menstrual changes such as spotting or bleeding before their next period. Some women may have a heavier or lighter next period, or a period that is early or late. If your period is more than a week late, you should get a pregnancy test.
However, if you should vomit within 1 hour of taking either Plan B® tablet, call your healthcare professional to see if you should repeat the dose.
Although Plan B® is safe and effective, it is not right for every woman. Do not use Plan B®
- If you are already pregnant, because Plan B® will not work
- If you are allergic to levonorgestrel or any of the ingredients in Plan B®
- If you have abnormal vaginal bleeding that has not been evaluated by a healthcare professional
- In place of regular birth control
Remember, Plan B® is not a substitute for routine birth control, and it does not protect you from HIV infection (the virus that causes AIDS) and any other sexually transmitted disease (STD).
