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

Summary:

Drug interactions are reported among people who take Fentanyl (fentanyl citrate) and Byetta (exenatide synthetic). Common drug interactions include infection among females and pancreatic carcinoma metastatic among males.

The phase IV clinical study analyzes what interactions people have when they take Fentanyl and Byetta. It is created by eHealthMe based on reports of 82 people who take the same drugs from the FDA, and is updated regularly.
