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

Summary:

Drug interactions are reported among people who take Fentanyl (fentanyl citrate) and Venofer (iron sucrose). Common drug interactions include atelectasis among females and dyspnoea among males.

The phase IV clinical study analyzes what interactions people have when they take Fentanyl and Venofer. It is created by eHealthMe based on reports of 82 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 fentanyl citrate and iron sucrose (the active ingredients of Fentanyl and Venofer, respectively), and Fentanyl and Venofer (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.

How to use the study?
