Tips for avoiding drug/grapefruit juice interactions

June 18, 2012

• Ask your pharmacist or other health care professional if you can have fresh grapefruit or grapefruit juice while using your medication.

• Read the medication guide or patient information sheet that comes with your prescription medicine to find out if it could interact with grapefruit juice.

• Read the drug facts label on your nonprescription medicine, which will let you know if you shouldn’t have grapefruit or other fruit juices with it.

• If you must avoid grapefruit juice with your medicine, check the label of bottles of fruit juice or drinks flavored with fruit juice to make sure they don’t contain grapefruit juice.

• Seville oranges (often used to make orange marmalade) and tangelos (a cross between tangerines and grapefruit) affect the same enzyme as grapefruit juice, so avoid these fruits as well if your medicine interacts with grapefruit juice.
