И сега какви, като пия противозачатъчки - никакви грейпфрути
Зависи какви са противозачатъчните, ако са на базата на естроген, е по-добре да избягваш грейпфрутите.

Grapefruit Juice: Grapefruit juice is one of the few foods that interacts with prescription drugs. Grapefruit juice causes some drugs to be absorbed too quickly - a dangerous effect for people taking drugs with high potential for toxicity or serious side effects. Don't drink grapefruit juice if you take calcium channel blockers for high blood pressure. The combination can be fatal! Grapefruit juice can also have dangerous interactions with drugs for allergies like Claritin and Allegra, antihistamines like Benadryl, and high blood pressure drugs. Grapefruit juice may interact with organ transplant drugs, estrogens and oral contraceptives, anti-anxiety medications, Methadone, Viagra, HIV drugs, seizure drugs and statin drugs for high cholesterol. Note: While grapefruit juice has the reputation for interactions, the fruit may have the same effect if consumed in large amounts.
Possible Harmful Interaction
Grapefruit juice slows the body's normal breakdown of several drugs, including estrogen, allowing it to build up to potentially excessive levels in the blood.14 A recent study indicates this effect can last for 3 days or more following the last glass of juice.15
If you take estrogen, the safest approach is to avoid grapefruit juice altogether.
Studies have shown that grapefruit juice significantly increases estradiol levels in the blood.1 2 One of the flavonoids found in grapefruit juice is quercetin. In a test tube study, quercetin was found to change estrogen metabolism in human liver cells in a way that increases estradiol levels and reduces other forms of estrogen.3 This effect is likely to increase estrogen activity in the body. However, the levels of quercetin used to alter estrogen metabolism in the test tube were much higher than levels found in the body after supplementing with quercetin.
There is evidence from test tube stuudies that another flavonoid in grapefruit juice, naringenin, also has estrogenic activity.4 It has yet to be shown that dietary or supplemental levels of quercetin (or naringenin) could create a significant problem.
