Procardia and Jakafi drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Procardia (nifedipine) and Jakafi (ruxolitinib phosphate). Common drug interactions include dizziness among females and acute myeloid leukaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Procardia and Jakafi. It is created by eHealthMe based on reports of 40 people who take the same drugs from the FDA, and is updated regularly.

What is Procardia?

Procardia has active ingredients of nifedipine. It is often used in high blood pressure. eHealthMe is studying from 15,151 Procardia users. Check the latest studies of Procardia.

What is Jakafi?

Jakafi has active ingredients of ruxolitinib phosphate. It is often used in primary myelofibrosis. eHealthMe is studying from 56,530 Jakafi users. Check the latest studies of Jakafi.
