Plan B® (levonorgestrel) is an emergency contraceptive used to prevent pregnancy in women who have had unprotected sex. However, because Plan B is not suitable for everyone, make sure to review the prescribing information on this medication before starting treatment.
For example, you may not be able to take Plan B if you have certain medical conditions, such as
diabetes or certain
allergies. Also, you may not be able to safely use this drug if you are currently taking certain medications (including some vitamins, herbal supplements, and nonprescription medications).
Although most people do not experience problems with this medication, Plan B can cause side effects -- common ones include nausea, fatigue, and
headaches.
If a fertilized egg has already implanted into the uterus, Plan B will not cause an abortion.
