Flagyl and Omniscan drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Flagyl (metronidazole) and Omniscan (gadodiamide). Common drug interactions include skin lesion among females and nephrogenic systemic fibrosis among males.

The phase IV clinical study analyzes what interactions people have when they take Flagyl and Omniscan. It is created by eHealthMe based on reports of 20 people who take the same drugs from the FDA, and is updated regularly.

What is Flagyl?

Flagyl has active ingredients of metronidazole. It is often used in vaginitis bacterial. eHealthMe is studying from 25,897 Flagyl users. Check the latest studies of Flagyl.
