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

Summary:

Drug interactions are reported among people who take Nuedexta (dextromethorphan hydrobromide; quinidine sulfate) and Warfarin sodium (warfarin sodium). Common drug interactions include dysstasia among females and memory impairment among males.

The phase IV clinical study analyzes what interactions people have when they take Nuedexta and Warfarin sodium. It is created by eHealthMe based on reports of 18 people who take the same drugs from the FDA, and is updated regularly.
