Pepcid ac and Cefdinir drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Pepcid ac (famotidine) and Cefdinir (cefdinir). Common drug interactions include chronic kidney disease among females and chronic kidney disease among males.

The phase IV clinical study analyzes what interactions people have when they take Pepcid ac and Cefdinir. It is created by eHealthMe based on reports of 65 people who take the same drugs from the FDA, and is updated regularly.
