Mercaptopurine and Vistaril drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Mercaptopurine (mercaptopurine) and Vistaril (hydroxyzine hydrochloride). Common drug interactions include ovarian cyst among females and abdominal pain among males.

The phase IV clinical study analyzes what interactions people have when they take Mercaptopurine and Vistaril. It is created by eHealthMe based on reports of 17 people who take the same drugs from the FDA, and is updated regularly.
