  |  by 

We’ve heard of prescription drug interactions (with other drugs), but did you know there are food-drug interactions too? Particular combinations can affect both the efficacy (doing what it’s supposed to) and side effects of the medication, as well as how the body metabolizes the food. Some common food-drug interactions include*:

Drug Type
Effect in Combination
1. Vitamin K (green, leafy vegetables)
Aspirins, warfarin
Decreased effectiveness in how well the drug thins the blood
2. Grapefruit juice
Statins, calcium channel blockers, erectile dysfunction (ED) drugs, chemotherapies, immune-suppressing drugs, allergy medications
Greater side effects; fluctuating levels of medication in the body
3. Dairy
Decreased effectiveness in how the drug is absorbed.

Insulin/oral diabetic pills

Lower blood sugar

Sudden, dangerous increase in blood pressure
6. Potassium (bananas, avocados, tomatoes, dried apricots, potatoes, spinach, white beans)
ACE inhibitors
Heart arrhythmias
7. High-fiber foods (soybean flour, walnuts
Levothyroxine & Digoxin
