Warfarin sodium and Excedrin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Warfarin sodium (warfarin sodium) and Excedrin (acetaminophen; aspirin; caffeine). Common drug interactions include cardiac myxoma among females and influenza among males.

The phase IV clinical study analyzes what interactions people have when they take Warfarin sodium and Excedrin. It is created by eHealthMe based on reports of 35 people who take the same drugs from the FDA, and is updated regularly.

How the study uses the data?

The study uses data from the FDA. It is based on warfarin sodium and acetaminophen; aspirin; caffeine (the active ingredients of Warfarin sodium and Excedrin, respectively), and Warfarin sodium and Excedrin (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.
