Activase and Valacyclovir drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Activase (alteplase) and Valacyclovir (valacyclovir hydrochloride). Common drug interactions include alanine aminotransferase increased among females and anaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Activase and Valacyclovir. It is created by eHealthMe based on reports of 12 people who take the same drugs from the FDA, and is updated regularly.
