Cysteine and Forteo drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Cysteine (n - acetyl cysteine) and Forteo (teriparatide recombinant human). Common drug interactions include blood pressure decreased among females.

The phase IV clinical study analyzes what interactions people have when they take Cysteine and Forteo. It is created by eHealthMe based on reports of 16 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 n - acetyl cysteine and teriparatide recombinant human (the active ingredients of Cysteine and Forteo, respectively), and Cysteine and Forteo (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?
