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

Summary:

Drug interactions are reported among people who take Arimidex (anastrozole) and Forteo (teriparatide recombinant human). Common drug interactions include fatigue among females and hypertension among males.

The phase IV clinical study analyzes what interactions people have when they take Arimidex and Forteo. It is created by eHealthMe based on reports of 80 people who take the same drugs from the FDA, and is updated regularly.
