What Makes it Different

  • All brands, including Portia, that contain the progestin levonorgestrel have been FDA approved for use as an Emergency Contraceptive.
  • Speak to a healthcare professional before using Portia as Emergency Contraception.
  • To use Portia as an Emergency Contraceptive, take all indicated pills no more than 120 hours (five days) after unprotected sex. It is most effective when taken within 72 hours (three days).
  • Dosage for emergency contraception: take four pink pills and, exactly 12 hours later, take another four pink pills.

How it Works

Portia (ethinyl estradiol and levonorgestrel) utilizes a combination of the female hormones, estrogen and progestin, to prevent pregnancy in three ways. First, the hormones prevent ovulation (the release of an egg from one of the ovaries). Second, Portia causes the cervical mucus to thicken, which blocks sperm from reaching and fertilizing the egg. Third, Portia prevents the uterine lining from thickening, which makes it less hospitable to implantation.

Oral contraceptives are to be utilized only as a form of birth control. The Pill does not protect against the transmission of HIV (AIDS) or other sexually transmitted infections (STIs).

How to Use

Take your first pill on the first day of your period or the first Sunday after your period has begun. Use Portia exactly as your healthcare provider has instructed. Do not take more often or for longer than your healthcare provider mandates.

Missing a dose of Portia increases the risk of pregnancy. There are ways to make up for missing a pill that will maintain the effectiveness of the birth control. Contact your healthcare provider for more information if you have missed one or more pills.


Portia is successful at preventing pregnancy in over 99% of situations when it is the only birth control method utilized and when Portia is used exactly as directed.


Most birth control pills cost between $15 and $50 per month.


When used as specified, Portia is an effective method of birth control. All birth control pills, Portia included, have also been shown to have the following possible benefits:

  • Menstrual cycle becomes more regular and blood flow is lightened (reducing the chances of anemia)
