How can you make the birth control patch fail?

The patch can fail if not put on right. If It's not staying on the right way, saying it got wet and is falling off, put on a new one soon as you can. Remebering when you need to change the patch will help form the patch failling.

Answer

Different medicines and some teas I have heard can affect the effectivmess of the patch. Calling your local pharmacist or the hospital or even a doctor and they could give you the list of the things that can affect the patch

The ortho evra patch is very effective in order for it to fail you would have to not use it properly and if you take antibiotics it increases your changes of getting pregnant.
