Fentanyl-100 and Gentamicin drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Fentanyl-100 (fentanyl) and Gentamicin (gentamicin sulfate). Common drug interactions include toothache among females and abdominal distension among males.

The phase IV clinical study analyzes what interactions people have when they take Fentanyl-100 and Gentamicin. It is created by eHealthMe based on reports of 30 people who take the same drugs from the FDA, and is updated regularly.
