An infection in the vagina, cervix, or uterus.An allergy to sulfa drugs, polyurethane, or spermicides.Vaginal bleeding or are having your period.Leave the sponge in the vagina for 6 to 8 hours after having sex.Push the sponge as far back into the vagina as possible, and place it over the cervix.Follow the specific instructions that came with the product.Vaginal contraceptive sponges are soft sponges covered with a spermicide.Ī sponge can be inserted into the vagina up to 24 hours before intercourse. Risks include irritation and allergic reactions. They may increase the risk for spreading HIV.

Spermicides do not reduce your chance of an infection. (Douching is never recommended, as it can cause infection in the uterus and tubes.) DO NOT douche for at least 6 hours after sex.You will need to use more spermicide every time you have sex.It should continue to work for about 60 minutes. Using your fingers or applicator, place the spermicide deep into the vagina 10 minutes before having sex.Even by using a spermicide alone, however, you are still much less likely to become pregnant than if you did not use any birth control.Using spermicides along with other methods, such as male or female condoms or the diaphragm, will reduce the chance of pregnancy even more.If spermicides are not used correctly, the risk of pregnancy is more than 25 for every 100 women each year.About 15 pregnancies occur out of every 100 women who correctly use this method alone over 1 year. Spermicides alone do not work very well.You can buy spermicides in most drug and grocery stores. They are inserted into the vagina before sex. They come as gels, foams, creams, or suppositories. Spermicides are chemicals that stop sperm from moving. However, using a spermicide or sponge is much better than not using birth control at all.
