Spermicide is a chemical that kills sperm. It is used to prevent pregnancy. It comes in different forms, such as foam, gel, cream, film, vaginal suppositories, and tablets. Spermicides work best when they are used with another form of birth control, such as a diaphragm or condom. You can buy a spermicide at a drugstore or grocery store without a prescription.
Spermicides are inserted into a woman's vagina before sex. During sex, the chemicals destroy the sperm in a man’s semen before the sperm can reach an egg.
If you have any questions, ask your healthcare provider or pharmacist for more information.
