My son started having chest pain last fall, after er visits that checked out ok, our family doctor says he has asthma.  these attacks occur at any time: sitting, walking. He has been on oxybutynin since last year aprox 2 months prior to this happening.  can this drug cause asthma type symptoms?
Howell come to ChatDoctorI really appreciate your concern this could be allergic asthma and may not be due to the medicine (Oxybutynin) chances of allergic asthma need to be ruled out, hope this information helps, take care, have a nice day.
