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

Summary:

Drug interactions are reported among people who take Cephalexin (cephalexin) and Methimazole (methimazole). Common drug interactions include arthralgia among females and renal failure among males.

The phase IV clinical study analyzes what interactions people have when they take Cephalexin and Methimazole. It is created by eHealthMe based on reports of 38 people who take the same drugs from the FDA, and is updated regularly.
