Psyllium and Atarax drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Psyllium (blond psyllium) and Atarax (hydroxyzine hydrochloride). Common drug interactions include chronic myeloid leukaemia among females and agranulocytosis among males.

The phase IV clinical study analyzes what interactions people have when they take Psyllium and Atarax. It is created by eHealthMe based on reports of 12 people who take the same drugs from the FDA, and is updated regularly.
