Allegra and Tranexamic acid drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Allegra (fexofenadine hydrochloride) and Tranexamic acid (tranexamic acid). Common drug interactions include blood urea increased among females and rib fracture among males.

The phase IV clinical study analyzes what interactions people have when they take Allegra and Tranexamic acid. It is created by eHealthMe based on reports of 45 people who take the same drugs from the FDA, and is updated regularly.
