Plan B One-Step is an emergency contraceptive pill that can help you avoid pregnancy if you’ve had unprotected sex or your birth control has failed. The pill contains a single highly concentrated dose of levonorgestrel, the same hormone found in many daily birth control pills. Levonorgestrel works by inhibiting the release of eggs, preventing them from fertilizing and implanting in the uterus. The drug is available over-the-counter in the form of a small tablet.
Plan B One-Step is eighty-seven percent effective, but certain medications or taking the pill past its expiration date may affect the effectiveness of the contraceptive. According to one study, more than one-third of American adults are taking prescription medications that have been linked to depression and suicide. Researchers found over 200 medications with possible negative health risks.
The best way to use Plan B is to take it 72 hours after having unprotected sex. The sooner you start taking it, the better it works. Plan B works for seven days, but it is not as effective as a regular birth control method.
Plan B has a number of side effects, such as upset stomach, lightheadedness, dizziness, and tender breasts. However, it is a safe and effective way to avoid pregnancy in a hurry. While it’s effective, it does not protect against sexually transmitted infections. For that reason, you must use a condom during sexual activity.
