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

Summary:

Drug interactions are reported among people who take Famciclovir (famciclovir) and Pepcid (famotidine). Common drug interactions include chronic kidney disease among females and renal failure among males.

The phase IV clinical study analyzes what interactions people have when they take Famciclovir and Pepcid. It is created by eHealthMe based on reports of 45 people who take the same drugs from the FDA, and is updated regularly.
