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

Summary:

Drug interactions are reported among people who take Fentanyl (fentanyl citrate) and Selenium (selenium). Common drug interactions include spinal osteoarthritis among females and anxiety among males.

The phase IV clinical study analyzes what interactions people have when they take Fentanyl and Selenium. It is created by eHealthMe based on reports of 64 people who take the same drugs from the FDA, and is updated regularly.
