Mefenamic acid and Cyclophosphamide drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Mefenamic acid (mefenamic acid) and Cyclophosphamide (cyclophosphamide). Common drug interactions include cataract among females and bacterial infection among males.

The phase IV clinical study analyzes what interactions people have when they take Mefenamic acid and Cyclophosphamide. It is created by eHealthMe based on reports of 22 people who take the same drugs from the FDA, and is updated regularly.
