Cordarone and Tapazole drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Cordarone (amiodarone hydrochloride) and Tapazole (methimazole). Common drug interactions include pancreatic mass among females and pneumonitis among males.

The phase IV clinical study analyzes what interactions people have when they take Cordarone and Tapazole. It is created by eHealthMe based on reports of 26 people who take the same drugs from the FDA, and is updated regularly.
