No, it should not (especially if you are referring to the condom and not the oral contraceptive pill). This may be related to the CYP3A4 enzyme that is responsible for slowly breaking down many drugs and toxins in our body, with the OCP (oral contraceptive pill) being one of the affected drugs. This ensures that the drug levels (and of course toxin levels) do not stay in our bodies permanently. However grapefruit juice is an inhibitor of the enzyme, and as such it slows down the breakdown of the contraceptive in the body. By applying the double negative makes a positive rule, you'll understand that this would cause the effect of the drug to be "stronger" instead. However this does not mean that women should take less OCPs and more grapefruit juice if they want to prevent pregnancy, this "stronger" effect only happens in some drugs, but has yet to be proven in OCPs. St. John's Wort, which is available over the counter on the other hand is a CYP3A4 inducer, and that has the opposite effect in causing the OCP to be broken down faster, so it has been proven in some clinical trials that women on both should approach their doctor for advise on tailoring their OCP dosage, else be at higher risk of unexpected pregnancy
Prune juice does not affect how well the birth control pill works. There's no increased risk of pregnancy.
grapefruit can interact with birth control and certain antibiotics. so if you are sexually active and into grapefruits try a different contraceptive for a week after your last grapefruit
Grapefruit juice inhibits the metabolism of many medications, including cyclosporine, felodipine, nifedipine, nitrendipine, nisoldipine, carbamazepine, triazolam, and midazolam
No. It does not. Nor will it ever. That is a complete myth. The only ones you need to worry about, are ones like Fresca which contain REAL grapefruit juice. Grapefruit is known to interact with many drugs, including birth control. Grapefruit slows down your body's ability to eliminate the estrogen from your pills which leaves it circulating in your system longer which then greatly increases all of the risks that birth control carries. You can still drink it, (I do) but sparingly and not often.
Sprite does not have grapefruit juice. There is a grapefruit juice which has sprite in it. You can add sprite to nearly any drink to make a spritzer.
Grapefruit juice is an inhibitor of enzymes.
No. Some medications give instructions not to have grapefruit juice with the medicine. I know statins are explicit about not having grapefruit juice.
