Promethazine and Ceftazidime drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Promethazine (promethazine hydrochloride) and Ceftazidime (ceftazidime). Common drug interactions include essential hypertension among females and white blood cell count decreased among males.

The phase IV clinical study analyzes what interactions people have when they take Promethazine and Ceftazidime. It is created by eHealthMe based on reports of 42 people who take the same drugs from the FDA, and is updated regularly.
