Levaquin and Ceftazidime drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Levaquin (levofloxacin) and Ceftazidime (ceftazidime). Common drug interactions include metastases to lung among females and anaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Levaquin and Ceftazidime. It is created by eHealthMe based on reports of 86 people who take the same drugs from the FDA, and is updated regularly.

What is Levaquin?
