How other medicines diminish the effectiveness of birth control pills?

The active ingredients of birth control contraceptives are hormones oestrogen and progesterone, which prevent ovulation and protect you from pregnancy. Most medications possess enzyme inducers to exert their effects. These enzyme inducers speed up the processing and metabolism of hormones inside your body. So, when these enzyme inducers interact with contraceptive hormones, they lower hormonal levels and lessen their effectiveness.
