Dulcolax and Cayston drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Dulcolax (bisacodyl) and Cayston (aztreonam). Common drug interactions include infective pulmonary exacerbation of cystic fibrosis among females and ventricular pre-excitation among males.

The phase IV clinical study analyzes what interactions people have when they take Dulcolax and Cayston. It is created by eHealthMe based on reports of 20 people who take the same drugs from the FDA, and is updated regularly.
