Fenoterol hydrobromide and Methotrexate drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Fenoterol hydrobromide (fenoterol hydrobromide) and Methotrexate (methotrexate sodium). Common drug interactions include asthma among females and bronchopulmonary aspergillosis among males.

The phase IV clinical study analyzes what interactions people have when they take Fenoterol hydrobromide and Methotrexate. It is created by eHealthMe based on reports of 21 people who take the same drugs from the FDA, and is updated regularly.
