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.
What is Saizen?
Saizen has active ingredients of somatropin recombinant. eHealthMe is studying from 3,122 Saizen users. Check the latest studies of Saizen.
What is Methotrexate?
Methotrexate has active ingredients of methotrexate sodium. It is often used in rheumatoid arthritis. eHealthMe is studying from 604,312 Methotrexate users. Check the latest studies of Methotrexate.
14 people who take Saizen and Methotrexate together, and have interactions are studied.

How the study uses the data?
The study uses data from the FDA. It is based on somatropin recombinant and methotrexate sodium (the active ingredients of Saizen and Methotrexate, respectively), and Saizen and Methotrexate (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.
