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

Summary:

Drug interactions are reported among people who take Imodium (loperamide hydrochloride) and Quinine (cinchona). Common drug interactions include nerve root compression among females and flatulence among males.

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