How is the sponge contraceptive used?

If the brand is "Today" the sponge needs to run under water until thoroughly wet before inserted. Other brands are Protectaid and Pharmatex and come ready to use.

The sponge can be inserted up to 24 hours before intercourse, over the cervix (beginning of the uterus). It must be left in place for at least six hours after the last time you have intercourse. It should not be worn for more than 30 hours in a row.

Note that contraceptive sponges do not protect against STD's and are only 75 to 99% effective in preventing pregnancy. It is wise to use the sponge accompanied by a condom or the pill.
