If you get irritated using spermicide, you're probably allergic to it. Unfortunately, all spermicides and contraceptive gels sold in the United States contain the same active ingredient, Nonoxynol-9.

Spermicide is a contraceptive substance that destroys sperm, inserted vaginally prior to intercourse to prevent pregnancy. As a contraceptive, spermicide may be used alone. However, the pregnancy rate experienced by couples using only spermicide is higher than that of couples using other methods. Usually, spermicides are combined with contraceptive barrier methods such as diaphragms, condoms, cervical caps, and sponges.
