If you've had unprotected sexual intercourse, or are worried that your method of contraception has failed, you can choose emergency contraception.
Birth control failure can result from broken condoms, a diaphragm slipping out of place, several missed birth control pills during the two weeks before intercourse, or more than two to three birth control pills missed in a row.
In accordance with the Affordable Care Act (ACA) requirements for preventive services, most of our plans cover emergency contraceptive pills in full. You may get emergency contraception through your personal primary care provider. Or in Washington state, emergency contraception is also available in retail pharmacies without a prescription at no cost. No exam is needed if you decide to use a pill form of emergency contraception.
One of Kaiser Permanente's recommended emergency contraception options is known as levonorgestrel (EContra EZ), a form of the female hormone progesterone. If taken within three to five days after you have unprotected sex, it can prevent pregnancy in at least 80 percent of cases. It's most effective when one pill is taken soon after intercourse. If you're treated more than 72 hours after having unprotected sex, your chance of getting pregnant is higher.
If it's been more than five days since you had unprotected sex or a birth control failure, and you are not trying to get pregnant, contact your personal physician, a women's health care provider, or our Consulting Nurse Service to discuss options and next steps. Emergency contraception pills are not intended as routine contraception, and will not protect you from sexually transmitted disease.
Emergency contraception uses a high dose of hormones to disrupt the process of fertilization. There are different types of emergency contraceptive pills. Typically, the emergency contraceptive pill is taken in one dose. This may vary depending on the brand, so it's always essential to follow the instructions that come with the pills.
No serious side effects have been reported in women who have used these emergency contraception drugs. In general, birth control pills are not known to cause fetal defects if a pregnancy occurs. However, it's not known for certain that evonorgestrel or other emergency contraception drugs are completely safe for the fetus if the pills don't prevent a pregnancy.
If you use emergency contraception, your next period will usually start within a few days of its normal timing. If your normal period hasn't started within four weeks of taking emergency contraception, or if your period arrives but is abnormal, you should have a pregnancy test and possibly be examined by your doctor.
