Flagyl and Tambocor drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Flagyl (metronidazole) and Tambocor (flecainide acetate). Common drug interactions include lower gastrointestinal haemorrhage among females and arthralgia among males.
The phase IV clinical study analyzes what interactions people have when they take Flagyl and Tambocor. It is created by eHealthMe based on reports of 6 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 25,896 Flagyl users. Check the latest studies of Flagyl.
