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

  • They're easy to get.

  • No prescription is needed.

  • Either partner can apply them, so responsibility can be shared.

  • They come in many forms.

  • They're easy to stop if you decide you want to become pregnant.

Cons

  • They have a high pregnancy rate when used alone.
