hi doctor my twins are 8yrs old, they were found to be highly allergic to grass and pollen, this year they have been coughing since January, i took them to their doctor and she prescribed Duolin, pulmicort, Nasonex for six months, the cough and flames persisted i then took them to the physio, she said I should continue nebulising, and i also gave them over the counter cough meds, the cough was quiet for a very short time, it has started again and im going back to the doctor, should i ask for an antibiotic this time around, its as if a piece of her flash will comeout when she coughs. Are there any side effects of the prescription over a period of time?In December they were with their cousin who an unchecked coughs only at night, what is this cough all about?
