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

Summary:

Drug interactions are reported among people who take Fentanyl (fentanyl citrate) and Optimark (gadoversetamide). Common drug interactions include skin burning sensation among females and nephrogenic systemic fibrosis among males.

The phase IV clinical study analyzes what interactions people have when they take Fentanyl and Optimark. It is created by eHealthMe based on reports of 27 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 gadoversetamide (the active ingredients of Fentanyl and Optimark, respectively), and Fentanyl and Optimark (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?
