Thank You For Your Promp Attention To This Matter As

Thank you for your promp attention to this matter as my 66 year old mother has a cough but suffers from OCPD ,EMPHESYMA,ASTHMA, and has suffered a few minnie strokes until she took couple bad ones that has effected her ability to walk without wobbily legs and making it to the bathroom is a chore as she hanks unto the walls and whatever she can its almost like she thinks the floor is gonna come out from under her feet. Anyways she has had a cough not consistently but when she starts coughing she coughs for quite awhile so my Step dad bought Buckleys cough syrup Chest Decongestant . I am concerned because I have asthma and I am not supposed to take it and I need to know if it would be exceptable for my mom or if there is a high risk factor due to her health issues. If there is what would u recommend? YYYY@YYYY
