So,I have gas and bloating and also the above problem as well.Doc suggested me to use otrivin oxy nasal spray for clearing eustachian tube,3 times a day for a week.And also gave other tablets for gas and bloating.Is it necessary to use this spray will it make other tablets not work well if I don't use it? I don't have severe congestion,except runny nose and cough.I think 3 times a day is too much,and the label says to use nose spray for only 3 days ,1-2 times.I already skipped one day,and today I used only once in the morning and I feel uncomfortable.I also last  used anxiety meds before July 6,will these tablets and spray interfere?
