Choosing a Birth Control Method – Spermicides

(Updated June 2014)

Description

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.

Use

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.

Effectiveness

This method is somewhat effective. Spermicides have a failure rate of 18% with perfect use and 28% with typical use.¹⁹

Risks

Possible mucosal damage to the vagina and cervix with high or prolonged exposure⁹¹

Side Effects

Increased risk of vaginal irritation, yeast infection, bacterial vaginosis, UTI, and HIV transmission with frequent use (twice daily or more).⁹¹
