(Page 2)
VAGINAL SPONGE
- Vaginal contraceptive sponges are soft artificial sponges covered with a spermicide. Before intercourse, the sponge is moistened, inserted into the vagina, and placed over the cervix. After intercourse, the sponge is left in place for 6 - 8 hours.
- The sponge is similar to the diaphragm (which you must get from a doctor) as a barrier protection method.
- About 18 - 28 pregnancies occur out of every 100 women using this method over 1 year. The sponge may be more effective in women who have not already given birth to a baby.
-
Risks include irritation, allergic reaction, trouble removing the sponge. In rare cases, toxic shock syndrome may occur.

EMERGENCY ("MORNING AFTER") BIRTH CONTROL
- The "morning after" pill consists of two doses of hormone pills taken within 72 hours after unprotected intercourse.
- The emergency contraceptive pill is available as either single pill (Plan B One-Step) or as two pills (Plan B, Next Choice). See: Emergency contraception
