Coumadin and Tobi drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Coumadin (warfarin sodium) and Tobi (tobramycin). Common drug interactions include decreased interest among females and dyspnoea among males.
The phase IV clinical study analyzes what interactions people have when they take Coumadin and Tobi. It is created by eHealthMe based on reports of 13 people who take the same drugs from the FDA, and is updated regularly.
What is Coumadin?
Coumadin has active ingredients of warfarin sodium. It is often used in blood clots. eHealthMe is studying from 133,228 Coumadin users. Check the latest studies of Coumadin.
What is Tobi?
Tobi has active ingredients of tobramycin. eHealthMe is studying from 10,011 Tobi users. Check the latest studies of Tobi.
13 people who take Coumadin and Tobi together, and have interactions are studied.
