Cefazolin sodium and Singulair drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Cefazolin sodium (cefazolin sodium) and Singulair (montelukast sodium). Common drug interactions include extrasystoles among females.

The phase IV clinical study analyzes what interactions people have when they take Cefazolin sodium and Singulair. It is created by eHealthMe based on reports of 15 people who take the same drugs from the FDA, and is updated regularly.
