Theo-dur and Meropenem drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Theo-dur (theophylline) and Meropenem (meropenem). Common drug interactions include cardiac failure among females and altered state of consciousness among males.

The phase IV clinical study analyzes what interactions people have when they take Theo-dur and Meropenem. It is created by eHealthMe based on reports of 11 people who take the same drugs from the FDA, and is updated regularly.
