Coumadin and Ionamin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Coumadin (warfarin sodium) and Ionamin (phentermine resin complex). Common drug interactions include pain among females and cerebrovascular accident among males.

The phase IV clinical study analyzes what interactions people have when they take Coumadin and Ionamin. It is created by eHealthMe based on reports of 21 people who take the same drugs from the FDA, and is updated regularly.
