When taking Fluzoparib Capsules, you must avoid grapefruit and any foods or beverages containing grapefruit ingredients. You should also reduce intake of high-fat, spicy, raw, cold and irritating foods, and abstain from alcohol strictly. All specific dietary adjustments shall be in accordance with your doctor’s advice.
I. Foods to Be Strictly Avoided
Grapefruit and grapefruit-containing products
Furanocoumarins in grapefruit can inhibit the activity of the hepatic metabolic enzyme CYP3A4, which may elevate the blood concentration of fluzoparib and increase the risk of adverse effects such as anemia and nausea.
Alcoholic beverages
Alcohol may add to the liver’s metabolic burden from the medication and exacerbate fluzoparib-induced adverse reactions including fatigue and nausea.
II. Foods to Be Minimized or Consumed with Caution
High-fat foods (e.g., fried foods, fatty meat)
A high-fat diet may delay drug absorption and compromise therapeutic efficacy. It is recommended to maintain a light diet and avoid excessive consumption of such foods during the medication period.
Spicy, raw, cold and irritating foods (e.g., chili peppers, iced drinks, sashimi)
These foods may irritate the gastrointestinal tract and worsen fluzoparib-induced gastrointestinal reactions like diarrhea and nausea.
Caffeine-containing foods and drinks (e.g., strong tea, coffee)
Caffeine may aggravate insomnia or palpitations caused by fluzoparib, so moderate intake is advised.
III. Other Precautions
Do not take health supplements or traditional Chinese medicines without professional guidance
Supplements such as St. John’s Wort and Ginkgo biloba extract may interfere with drug metabolism. You must inform your doctor of any supplements you are taking in advance.
Time interval between medication administration and meals
If the drug needs to be taken with meals, opt for low-fat, easily digestible foods and take the medication at a fixed time to ensure a stable blood concentration of fluzoparib.
