The Medical Letter has developed a database of adverse drug interactions, which is the source for our desktop computer, online and PDA/handheld software. The data files contain over 2000 pairs of interacting drugs. Each listing contains one or more adverse effects with a mechanism of action. Following the adverse effects are pertinent reference citations documenting the effect, followed by comments and recommendations. The database contains an index of over 3,000 brand names. The interactions and index are approximately 1.2MB in size before compression. For information about our Adverse Drug Interactions database, read frequently asked questions.

The Medical Letter offers this data for licensing by software developers or as a data source for those who would like to supplement current databases with drug interaction information.
