How do I use it?
Spermicide (in any form) is placed deeply inside the vagina and works by killing sperm before it reaches an egg. Instructions are different for each type of spermicide, so read the label carefully before use. Some types of spermicide (like tablets and films) should be in place at least 10 minutes before you have sex, otherwise they won't be effective.
With any type of spermicide, don't insert it more than one hour before having sex. Spermicide should remain in the vagina at least six hours after sex.
