Use emergency contraception as a backup if a condom breaks or slips off.

Using an additional method of birth control is a good backup measure in case a condom breaks.

That night, a condom breaks and Robin becomes pregnant, although she is unaware of this until weeks later.

Emergency contraception is a backup method to prevent pregnancy if you forget to use birth control or a condom breaks.

But for single unique events, or for when the condom breaks, my suspicion is that it may be a reasonable thing to do.

Lubrication may give some extra protection in preventing pregnancy, especially if the condom breaks.

These methods are very dangerous and potentially lethal; if the condom breaks, the drugs inside become absorbed into the bloodstream and can cause an overdose.
