Hi, My son is 7 years old and has been wheezing for about 2 mths now. After a couple of visits to our paediatricain, he has now prescribed Omancortil 10 mg ( 3 times a day) for 5 days to put an end to the wheezing. However, we notice that since we started Omancortil 10 from the last 2 days, my son has been looking lethargic and drowsy/tired as compared to before we started it. He wants to sleep longer than normal.Otherwise he is an active, energetic child. Is this kind of symptom an expected side-effect of Omancortil 10 during its use or if not should we consult our paed again.
