That’s a good question, sometimes I believe it’s because other medications could be interfering with its mechanisms; also not to account for failure necessarily, it is to prevent a law suite. If the claim was 100% effective and for some unknown reason someone became pregnant, the company who manufactures and markets that contraceptive could be held liable.

I hope this helps :)
