Birth Control: Spermicides

Spermicides help prevent pregnancy by killing sperm before they can enter the uterus. They come in many forms, including foam, jelly, film, and suppository-like inserts. These can be bought in drugstores without a prescription.

Using spermicides

• For best protection against pregnancy, use spermicides with a barrier method (condom, diaphragm, or cervical cap).

• Apply before there is any contact between the penis and vagina.

• Check the package for instructions on how to apply.

• Reapply each time you have sex.

• Don't douche or use tampons for 6 to 8 hours after using a spermicide.

Pros

• Easy to get
