Rythmol and Imodium drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Rythmol (propafenone hydrochloride) and Imodium (loperamide hydrochloride). Common drug interactions include cough among females and hypotension among males.

The phase IV clinical study analyzes what interactions people have when they take Rythmol and Imodium. It is created by eHealthMe based on reports of 14 people who take the same drugs from the FDA, and is updated regularly.
