Guide to Food and Drug Incompatibility

There are many factors to consider when it comes to administering a patient's medications. One such factor that is often overlooked, especially by patient's, is food-drug interaction. Some foods will cause drugs to work more quickly or more slowly, or may be more efficable when taken with, or without, food. Other foods may cause adverse reactions when taken with certain medications, such as causing new side effects. Use this guide to help you remember some common food-drug incompatibilties.

This list is not intended to be a comprehensive list of all food-drug interactions and should be used for reference only.
