Nexium and Foscavir drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Nexium (esomeprazole magnesium) and Foscavir (foscarnet sodium). Common drug interactions include septic shock among females and alanine aminotransferase increased among males.

The phase IV clinical study analyzes what interactions people have when they take Nexium and Foscavir. It is created by eHealthMe based on reports of 33 people who take the same drugs from the FDA, and is updated regularly.

What is Nexium?

Nexium has active ingredients of esomeprazole magnesium. It is often used in gastroesophageal reflux disease. eHealthMe is studying from 245,678 Nexium users. Check the latest studies of Nexium.

What is Foscavir?

Foscavir has active ingredients of foscarnet sodium. eHealthMe is studying from 1,631 Foscavir users. Check the latest studies of Foscavir.
