What is spermicide in mouth?

It is not recommended to use spermicide in the mouth. Spermicide is a contraceptive agent that is designed to be used in the vagina to prevent pregnancy. It contains chemicals that are harmful if ingested, and there is no evidence to suggest that it would be effective if used in the mouth. If you have concerns about contraception or sexually transmitted infections, it is important to speak with a healthcare provider to determine the best course of action.
