Excedrin and Niaspan drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Excedrin (acetaminophen; aspirin; caffeine) and Niaspan (niacin). Common drug interactions include eye pain among females and flushing among males.
The phase IV clinical study analyzes what interactions people have when they take Excedrin and Niaspan. It is created by eHealthMe based on reports of 57 people who take the same drugs from the FDA, and is updated regularly.
