Emergency Contraception

Emergency contraception, also known as the morning-after pill, EC, or Plan B, is available at all Planned Parenthood health centers in the St. Louis region and southwest Missouri.

EC is available at all health centers on a walk-in basis.

EC can stop a pregnancy before it starts. That means it's not the abortion pill. It works up to five days, or 120 hours, after unprotected sex. The sooner you take it, the higher your chances are to prevent pregnancy.

There Are Three Types of Emergency Contraception


The newest form of emergency contraception in the U.S. is a one-pill formula available by prescription only. Ella blocks the hormones your body needs to conceive. It's completely effective for five days after unprotected sex.

Plan B/Next Choice

Plan B/Next Choice works like birth control pills, but at a much higher dose. It works up to five days after unprotected sex, but the sooner you take it, the better it'll work.

Plan B/Next Choice is a two-pill formula where you take one right away and the second within 12 hours. The newer version, called Plan B-One Step, is a bit more expensive (but it's just one pill).

Intrauterine Device (IUD)

The IUD is the most effective emergency contraception there is. At Planned Parenthood, we'll insert it within five days of the unprotected sex and lower your chance of pregnancy by 99.9%.

Where Can I Get Emergency Contraception?

You can purchase emergency contraception at any Planned Parenthood location on a walk-in basis. It costs $25 and we accept cash, check, credit and debit. Please remember to bring a valid state ID when coming to purchase emergency contraception.

**For patients 17 and under who purchasing the ELLA method only, there is an additional $10 copay for the office visit (so you'll need to make an appointment).

If You Want An IUD

Then you'll need to make an appointment with us as well. We have eight health centers in the St. Louis region and Southwest Missouri, and all are able to help you get an IUD.
