What is it?
Spermicides come in several different forms, including creams, jellies, tablets, suppositories, foams, and film.
How does it work?
The spermicide, which is inserted into the vagina before intercourse, contains an ingredient that impairs the sperm. It should always be used with another form of contraception.
Does it prevent sexually transmitted infections?
Remember that most birth control or contraceptive methods will not protect a person from sexually transmitted infections (STIs). To reduce the risk of STIs, including HIV, use a condom with another method of contraception. This is referred to as dual protection.
To be effective, birth control must be used correctly and consistently. If you want to prevent pregnancy, choose a method that you and your partner will use every time you have intercourse.
Talk to your health-care provider or visit a sexual health clinic to find out what might work best for you and your partner.
