When did you have sex

without a contraceptive or have a contraceptive accident?

Please select a time earlier than the present.

You have hours remaining to take Plan B®.

The sooner you take Plan B®, the better it works. Plan B® can help prevent pregnancy if taken within 72 hours, and preferably within 12 hours, after a contraceptive accident or unprotected sex.

It has been more than 72 hours since you had unprotected sex or a contraceptive accident. Please contact a healthcare professional for advice.

The #1 choice of Canadian women.

Whatever happened during plan A, you can choose Plan B® as an effective emergency contraceptive as long as you take it within 72 hours (three days) of unprotected sex.

What is Plan B®?

Plan B® is the emergency contraceptive pill, most trusted by Canadian women and their healthcare providers.*

Plan B® contains 1.5 mg of levonorgestrel—an ingredient that is also commonly found in birth control pills.

How does Plan B® work?

If taken within 72 hours of unprotected sex or following a contraceptive accident, Plan B® works by:

  • Stopping ovulation temporarily
  • Preventing fertilization
  • Preventing implantation

Where can I buy Plan B®?

Plan B® is available on shelf in pharmacies across Canada, and you don’t need to visit your doctor first.

What should I expect?

You may experience some spotting a few days after taking Plan B®, but this is not your period. You should get your next period at the expected time, though it could be a few days early or late.

Avoid a “next time”

Plan B® is here if you need it, but it should not be your plan A for birth control.
