FAQ: Can I take birth control pills as emergency contraception?

Sometimes things don’t go as planned, condoms break, pills might get missed, or barrier methods might not be used properly. When that happens, you might wonder:

“Can I take extra birth control pills as emergency contraception (EC)?”  

While it is possible to take birth control pills as emergency contraception (EC), this method is less effective than others as Emergency Contraception and can lead to more noticeable side effects. Ultimately medical professionals recommend using this method only when no other options are available.

What is emergency contraception?

Emergency contraception (EC) helps lower your chances of getting pregnant after unprotected sex. EC needs to be used within a few days usually 3-5 days depending on the method.  EC does not cause an abortion, it works before pregnancy starts by delaying to stopping ovulation in the uterus. This prevents an egg (ovum) from being  released, so sperm can’t fertilize it.

There are a few types:

  • EC Pills
    • Plan B (over the counter)
    • Ella (prescription)
  • IUD

A copper IUD can be inserted as an EC option as well but needs to be done within 5 days.

Can you use regular birth control pills as EC?

Yes, technically you can. Birth control pills contain some of the same hormones as EC, which is why higher doses can work in an emergency.

  • Birth control pills have much lower hormones levels than EC pills
  • To use them as EC, you’d need to take a specific number of pills, and that number depends on the brand and whether they contain progestin
  • Figuring out the right dose can be confusing if you’re not a doctor

Because of this, using birth control pills as EC is considered a back up option, not the first choice. If you are thinking about doing this, it’s best to talk to a healthcare provider so you take the correct amount and stay safe.

Is using birth control pills as EC effective?

The truth is that:

  • Regular EC methods: up to 99% effective when used correctly
  • Birth control pills used as EC: around 74% effective

So, while it can work, it isn’t as reliable as Plan B, Ella, or an EC IUD.

Is it Safe to take multiple birth control pills?

Usually yes. Birth control hormones are ones your body naturally makes, so taking extra isn’t toxic.

But taking several pills at once can cause stronger side effects, like:

  • Nausea
  • Vomiting
  • Headaches
  • Mood changes
  • Breast soreness
  • Spotting or unexpected bleeding

These aren’t dangerous, but they can be uncomfortable and preventable when using standard EC options instead.

If your birth control routine isn’t working for you

That’s okay! Everyone’s decisions when it comes to birth control are allowed to be different.
