Eating pineapple an hour before taking the Dionelle contraceptive pill will not affect its effectiveness. Pineapple does not affect the effectiveness of hormonal contraception.

It is believed that citrus fruits can slow down the metabolism of the hormones contained in the pills, which is associated with an increase in the concentration of hormones in the body and their intensified effects. Like taking an extra pill, this does not affect the effectiveness of contraception, but may contribute to side effects such as spotting. The ingredients in pineapple do not have a strong effect on liver function and drug metabolism, so consuming it in normal amounts is unlikely to result in a significant effect on the effects of medications.
