What is it?
Spermicide is a chemical that kills sperm. The chemical is mixed into a medium that acts as the transport method, for example a cream, jelly, suppository, foam or film.
What do I need to know about using spermicide?
Spermicide agents are recommended for use with condoms, diaphragms, and cervical caps. When used with these items spermicide increases their effectiveness.
The dose of the sperm-killing chemical in each type of vaginal spermicidal product varies from product to product.
Women and men can have a sensitivity or allergy to spermicide. These reactions can include redness, itching, burning and swelling. If you have a sensitivity to one product you might try a different one (i.e. if a particular suppository causes you irritation, try a vaginal film or cream). However, if you consistently have irritation, itching or rash after using a spermicide, you should avoid use of these items until you speak to a health care provider.
Read the instructions carefully for each form of spermicide that you may use.
-
Suppositories and films require some time to dissolve before they offer any contraceptive benefit.
-
The spermicidal agent must be placed deep inside the vagina so that it comes in contact with the surface of the cervix.
-
If placed in the vaginal more than an hour prior to intercourse, additional spermicide must be used.
Effectiveness
Effectiveness ratings are very low when spermicides are used as the only method of contraception. When used in combination with a condom or diaphragm, effectiveness ratings increase. However, if no other method of birth control is available, using a spermicidal agent is certainly better than using nothing at all.
Additional information
A variety of spermicidal agents are available in supermarkets and drugstores.
-
Spermicides should be stored in cool dry location.
