Plan B Safety Information

Although most women tolerate Plan B One-Step™ (levonorgestrel) well, this medication is not suitable for everyone. Before starting treatment with this emergency contraceptive, make sure you talk to your healthcare provider about any safety information with Plan B that may apply to you.
For example, make sure your healthcare provider is aware of any other medical conditions you may have. You may not be able to take Plan B safely if you have certain medical conditions, such as diabetes or certain allergies.
Plan B may also cause drug interactions with certain medications, so it is important to inform your healthcare provider about any other medications you are taking, including nonprescription medications, vitamins, and herbal supplements.
Other information on Plan B safety concerns applies to women who are pregnant or breastfeeding. This drug is not effective at terminating an established pregnancy. Also, Plan B does pass through breast milk, so you should talk to your healthcare provider before using this contraceptive while breastfeeding.
