Drug Content Contributors

Aisle7 publishes content on medicines selected from data included with permission and copyrighted by First DataBank, Inc., a subsidiary of The Hearst Corporation, and a leading provider of electronic drug information. For more than two decades, they have delivered proven knowledge bases for integration into varied healthcare applications, with particular expertise in clinical decision support.

Our drug-nutrient interaction content is written by an Aisle7 team of experts in the fields of medicine, pharmacy, naturopathy, and public health. This information covers the ways in which common prescription and over-the-counter drugs interact with herbs, vitamins, and foods, including potential nutrient depletions, interference with drug actions, reduction of drug side effects, and interference with drug absorption (bioavailability) when taking herbs, nutritional supplements, or food with certain medications.
