Bicalutamide and Oxybutynin drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Bicalutamide (bicalutamide) and Oxybutynin (oxybutynin). Common drug interactions include fatigue among males.
The phase IV clinical study analyzes what interactions people have when they take Bicalutamide and Oxybutynin. It is created by eHealthMe based on reports of 92 people who take the same drugs from the FDA, and is updated regularly.
