Grapefruit juice

· Severity: Mild

· Notes for Consumers: Grapefruit juice and grapefruit-containing foods may increase the side effects of estrogen in some females, such as nausea, breast tenderness, headache or fluid retention. There may be no interaction. Do not significantly change your grapefruit intake while taking estrogens for hormone replacement therapy or as part of hormonal birth control products. Report any unusual side effects, like unusual non-menstrual vaginal bleeding, promptly for evaluation.

· Notes for Professionals: Grapefruit juice has been reported to decrease the metabolism of some estrogens. Grapefruit juice contains a compound that inhibits CYP3A4 in enterocytes. Estrogen levels may increase by up to 30 percent with chronic use. The clinical significance of the interaction is unknown. It is possible that estrogen induced side effects could be increased in some individuals. Patients should be advised to not significantly alter their grapefruit juice ingestion.When chronically ingesting any CYP3A4 inhibitor ( > 30 days) with estrogens, adequate diagnostic measures, including directed or random endometrial sampling when indicated by signs and symptoms of endometrial hyperplasia, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.
