Levofloxacin and Halcion drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Levofloxacin (levofloxacin; sodium chloride) and Halcion (triazolam). Common drug interactions include petechiae among females and cardiac failure among males.

The phase IV clinical study analyzes what interactions people have when they take Levofloxacin and Halcion. It is created by eHealthMe based on reports of 40 people who take the same drugs from the FDA, and is updated regularly.
