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

Summary:

Drug interactions are reported among people who take Saizen (somatropin recombinant) and Methotrexate (methotrexate sodium). Common drug interactions include erythema among females and hypertension among males.

The phase IV clinical study analyzes what interactions people have when they take Saizen and Methotrexate. It is created by eHealthMe based on reports of 14 people who take the same drugs from the FDA, and is updated regularly.
