Phenergan and Potassium phosphate drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Phenergan (promethazine hydrochloride) and Potassium phosphate (potassium). Common drug interactions include acute myeloid leukaemia among females and acetabulum fracture among males.

The phase IV clinical study analyzes what interactions people have when they take Phenergan and Potassium phosphate. It is created by eHealthMe based on reports of 19 people who take the same drugs from the FDA, and is updated regularly.
