Spermicides are creams, foams, gels, suppositories, and films that contain a chemical lethal to sperm. They can be used alone or together with a barrier method. Some condoms can be purchased at the pharmacy over the counter; others are available in the family planning aisle of pharmacies and retail stores.
Creams, foams, and gels are placed high up in the vagina, near the cervix, with a plastic plunger-type applicator. Spermicidal suppositories and films are inserted into the vagina and take 10–15 minutes to dissolve and become effective. Spermicides can be applied up to 1 hour before intercourse and must be reapplied with each act of intercourse. Women should not rinse the vagina or douche for at least 6 hours after the last act of intercourse.
This method is somewhat effective. Spermicides have a failure rate of 18% with perfect use and 28% with typical use.18
Possible mucosal damage to the vagina and cervix with high or prolonged exposure91
Increased risk of vaginal irritation, yeast infection, bacterial vaginosis, UTI, and HIV transmission with frequent use (twice daily or more).92
