Q: What are the different kinds of emergency contraception?
A: One type of emergency contraception uses hormones that are the same type
and dose as hormones used in some kinds of ordinary birth control pills
(estrogen and progestin: combined ECPs) and another type contains only
the hormone called progestin (progestin-only ECPs).
One brand name of combined ECPs is called Preven and is specially packaged and labeled for emergency use. There are several other brands packaged for ongoing contraception that can be used as well.
Progestin-only pills do not contain estrogens, only progesterone. This type is specially packaged and labeled for use as the brand name Plan B.
