<s>[INST] Hi My son is getting cough or get congestion again n again because of pollution. So this doc has recommended Montek LC kid for a month and Pedimmune for 1 month. She said will continue Montek for 1 more month. Since from last 6 mnths he is getting it again n again. [/INST] HI, thanks for using Chat Doctor If he is continuously exposed to the source of his allergies then the symptoms would recur despite medication. The medication would only help to reduce the symptoms but would not be able to eliminate them completely once the source of allergies is present. You would need to continue the medication (Monte) to help to reduce the intensity of his symptoms. I hope this helps </s>
