Spermicide
What is it?
Spermicide is a non-hormonal birth control that is available in several different forms, including creams, jellies, tablets, suppositories, foams, and film.
How does it work?
- Spermicide is inserted into the vagina in front of the cervix before intercourse.
- It contains an active ingredient (Nonoxynol-9) that destroys sperm.
- Always read the directions for use on the spermicide packaging.
- Some forms of spermicide, such as foam, require an applicator. Foam is effective immediately and up to one hour after insertion. Appy foam each time you have sex.
- Spermicide film must be inserted in the vagina at least 15 minutes before sex to allow time for it to melt and disperse. It is effective for up to three hours after insertion.
How effective is it?
Vaginal Spermicides are among the least effective form of birth control.
- Spermicide is 79% effective at preventing pregnancy
- 18–21 people out of 100 who use spermicide will become pregnant each year.
- Always use spermicide with another form of contraception, such as a condom, to prevent pregnancy.

Does it prevent sexually transmitted infections?
- Spermicide does not protect against sexually transmitted and blood-borne infections (STBBIs).
- To protect against pregnancy and STBBIs, use dual protection. This means using a condom and/or oral dam (dental dam) with another form of birth control each time you have sex.
- Talk to your healthcare provider or visit a sexual health clinic to find out what works best for you.
