Cephalexin and Stelara drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Cephalexin (cephalexin) and Stelara (ustekinumab). Common drug interactions include hypoaesthesia among females and pollakiuria among males.

The phase IV clinical study analyzes what interactions people have when they take Cephalexin and Stelara. It is created by eHealthMe based on reports of 63 people who take the same drugs from the FDA, and is updated regularly.
