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

Summary:

Drug interactions are reported among people who take Beyaz (drospirenone; ethinyl estradiol; levomefolate calcium) and Singulair (montelukast sodium). Common drug interactions include deep vein thrombosis among females and dyspnoea among males.

The phase IV clinical study analyzes what interactions people have when they take Beyaz and Singulair. It is created by eHealthMe based on reports of 46 people who take the same drugs from the FDA, and is updated regularly.
