Can I substitute Plan B one step with birth control pills?
Answer
Plan B contains a high dose (1.5 mg) of the progestin levonorgestrel. Levonorgestrel is the hormone that has been most studied to be both effective and safe for use as an emergency contraceptive.
Emergency contraceptives should be used as soon as possible after unprotected sex to decrease the chances of pregnancy. If you do not have access to Plan B, some brands of daily birth control pills can be substituted.
Below is a list of daily birth control pills that are generally considered safe and effective for emergency contraception when used in place of Plan B when Plan B is not available.
Unlike Plan B One-Step, the most daily pills when used as an emergency contraceptive need to be taken in 2 doses.
- The the first dose as soon as possible after unprotected sex (within 120 hours).
- Take the second dose 12 hours later.

While emergency contraception is considered safe, there can be acute side effects such as:
- Depression or depressed mood
- General mood changes
- Irritability
- Headache
- Migraine
- Dizziness
- Spotting and breakthrough bleeding
- Amenorrhea (missed period)
The above side effects tend to be mild and any menstrual changes (e.g. spotting or a missed period) should resolve when your next cycle begins.
If you are in a situation where emergency contraception is needed and you don't have access to Plan B, it would be prudent to speak with your doctor regarding whether or not using your daily birth control pills as an alternative is the right choice in your specific situation.
