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

Summary:

Drug interactions are reported among people who take Flagyl (metronidazole) and Cytovene (ganciclovir). Common drug interactions include cytomegalovirus colitis among females and cardiac tamponade among males.

The phase IV clinical study analyzes what interactions people have when they take Flagyl and Cytovene. It is created by eHealthMe based on reports of 17 people who take the same drugs from the FDA, and is updated regularly.

How the study uses the data?

The study uses data from the FDA. It is based on metronidazole and ganciclovir (the active ingredients of Flagyl and Cytovene, respectively), and Flagyl and Cytovene (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.
