吃药期间警惕“水果陷阱”

Core Insights - A recent case at Nanjing Maternal and Child Health Hospital highlighted the interaction between grapefruit and certain gynecological endocrine medications, leading to adverse effects in patients [1][2] Group 1: Drug Interactions - Grapefruit contains furanocoumarin compounds that inhibit the activity of the drug-metabolizing enzyme CYP3A4, resulting in increased blood concentrations of medications that require this enzyme for metabolism [1] - Common gynecological endocrine medications that should be avoided with grapefruit include: - Progesterone medications such as progesterone and dydrogesterone, which are used to regulate menstrual cycles and for pregnancy maintenance. Co-administration with grapefruit can lead to increased side effects like dizziness, drowsiness, and nausea, and in severe cases, fainting and palpitations [1] - Estrogen medications including estradiol and estradiol valerate, used for hormone replacement therapy and to alleviate perimenopausal symptoms. Grapefruit can enhance the effects of these medications, potentially leading to elevated estrogen levels and increased risks of breast tenderness and irregular vaginal bleeding [1] Group 2: Recommendations - Short-acting oral contraceptives may also interact with grapefruit, exacerbating symptoms such as nausea, dizziness, headaches, and breast tenderness. It is important to note that even a few hours' gap between taking medication and consuming grapefruit may still result in interactions, with sensitivity varying among individuals [2] - Medical professionals recommend avoiding grapefruit and grapefruit juice while taking the aforementioned medications. Patients are advised to consult their doctors if uncertain about the effects of certain fruits on their medication to ensure safety [2]
