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

Summary:

Drug interactions are reported among people who take Vistaril (hydroxyzine hydrochloride) and Stelazine (trifluoperazine hydrochloride). Common drug interactions include diabetic ketoacidosis among females and abdominal pain among males.

The phase IV clinical study analyzes what interactions people have when they take Vistaril and Stelazine. It is created by eHealthMe based on reports of 18 people who take the same drugs from the FDA, and is updated regularly.
