Plan B and Birth Defects

If pregnancy is not part of your plan at this time, regular use of a reliable form of birth control should be. However, sometimes slip-ups do occur. Maybe you’ve forgotten to take several birth control pills in a row. Perhaps a condom broke or slipped off. Or maybe it was just an occasion of unanticipated unprotected sex. When that happens, some women turn to Emergency Contraception (EC) – Plan B, an emergency contraception pill—to reduce the chance of pregnancy. So how does this work? What comes after that? And what about Plan B and birth defects?

Here’s some information to assist you with your questions about Plan B and birth defects.

What exactly is Emergency Contraception and Plan B?

Plan B and Plan B One-Step are brand names for a “morning after pill” which can be used as an emergency contraceptive after an instance of unprotected sex or the failure of another birth control method. The pill contains levonorgestrel, a hormone used in many birth control pills. Its dosage is higher, however, in the emergency contraception application. It is intended to stop a pregnancy from occurring by preventing or delaying ovulation in the woman (keeping an egg from maturing). It may also serve to block fertilization, or keep a fertilized egg from attaching inside the womb. In order to be effective, the pill(s) must be taken as soon as possible, up to 5 days, after unprotected sex. Effectiveness will increase the more quickly it is taken.

Using Emergency Contraception (EC) is not an abortifacient. It does not stop an established pregnancy. If a fertilized egg has already implanted, this pill will not work.

What is the danger of Plan B and birth defects?

What if a woman is pregnant when she takes the Plan B pill? Although specific studies have not been done for cases of a woman becoming pregnant after taking the “morning after pill,” it is considered extremely unlikely that use of emergency contraception would lead to birth defects. Studies have noted if a woman inadvertently continues taking birth control pills, not realizing at first that she is pregnant, there is no increased risk of birth defects. Additionally, emergency contraception would be used much earlier than fetal organs would begin to develop, further reducing the likelihood of birth defects.

We hope this information has been helpful for your immediate question about Plan B and birth defects.
