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

Summary:

Drug interactions are reported among people who take Fentanyl (fentanyl citrate) and Calcium lactate (calcium). Common drug interactions include dyspepsia among females and kidney transplant rejection among males.

The phase IV clinical study analyzes what interactions people have when they take Fentanyl and Calcium lactate. It is created by eHealthMe based on reports of 20 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 calcium (the active ingredients of Fentanyl and Calcium lactate, respectively), and Fentanyl and Calcium lactate (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?

DO NOT STOP MEDICATIONS without first consulting your doctor. If there are any serious or long term adverse effects discovered in the study, discuss the study with your doctor to ensure that proper medication management will be in place if applicable.
