Types of Emergency Contraception
Which birth control pills can be used for emergency contraception in the United States?
In the U.S., Plan B One-Step is available without age restrictions to women and men (check the family planning aisle). One-pill generics (My Way and Next Choice One Dose) will soon be available on the shelf for consumers aged 17 and older, but this change has not taken effect yet; women 16 and younger still need a prescription. Two-pill generics (Levonorgestrel Tablets) are still available only behind the counter without prescription if you are 17 or older; younger women need a prescription.
There are nearly two dozen brands of pills that can be used for emergency contraception in the United States today. Several products are specifically approved and marketed here as emergency contraceptive pills:
Plan B One-Step is sold on the shelf (check the family planning aisle) with no restrictions. That means anyone can buy it without having to show ID. Plan B One-Step generally costs about $40-50.
- Soon, the generic one-pill products (Next Choice One Dose and My Way) will be available on the shelf next to Plan B One-Step, but you need to be 17 to buy them. Be prepared to show ID to buy these products. These generics generally cost about $35-45.
- The generic two-pill products Levonorgestrel Tablets are still available only at the pharmacy counter. Women and men aged 17 or older can buy them without a prescription. If you are 16 or younger, you need a prescription.
- ella is sold by prescription only, regardless of age. You can also order ella through an online prescription service for $40, including shipping.
EC should be taken as soon as possible after sex. If you are using Levonorgestrel Tablets, take both doses at the same time. Plan B One-Step, Next Choice One Dose and My Way contain the same amount of progestin as Levonorgestrel Tablets, but there's only one pill to take.
You can also use a different dose of a number of brands of regular birth control pills. While these are not sold specifically as emergency contraceptive pills, they have been proven safe and effective for preventing pregnancy in the few days after sex. These daily birth control pills contain two hormones, progestin and estrogen, and are taken in two doses. You take the first dose as soon as possible (up to 120 hours after you have sex without using birth control, your birth control failed, or you were made to have sex against your will. You take the second dose 12 hours later (although being an hour or two early or late probably won’t make a difference in how effective the pills are).
Emergency contraceptive pills have no long-term or serious side effects, and it is safe for almost every woman to use them.
Here are some other things to know about taking emergency contraceptive pills:
- Don't take more than one kind of EC. The active ingredient in ella may counteract the effect of levonorgestrel, the active ingredient in Plan B One-Step and Next Choice One Dose.
- Don’t take extra pills. They probably won’t reduce your risk of pregnancy any more than the recommended dose for emergency contraception. But they will make it more likely you’ll feel sick to your stomach (one of the more common side effects).
- If you feel sick to your stomach, it should be only mild nausea that goes away in a day or so.
- If you throw up within an hour after taking the pills, call your health care provider. You may need to repeat a dose, and it might make sense to take some anti-nausea medication (Find out more about side effects here).
- If you have any other symptoms you are worried about,
contact your health care provider. Ask for an appointment right
away if you have:
- Severe pain in your leg (calf or thigh)
- Several abdominal pain
- Chest pain or cough or shortness of breath
- Severe headaches, dizziness, weakness, or numbness
- Blurred or loss of vision or trouble speaking
- Jaundice (if you see a yellowish tint in the whites of your eyes, your skin, or your mucus membranes)
- Your next period should start within the next month, although it might come a few days early or late (find out more here). If you don’t get your period by the time you expect it, you might consider getting a pregnancy test.
- Start using a regular birth control method you think you’ll be able to use every time you have sex because that will be more effective than relying only on emergency contraception. And, if there’s any chance you could be at risk of sexually transmitted infections, use a condom.
