[|Human|] My 17 year old son has a persistant dry cough especially at night for over  a long time. Last time , i took him to the doctor said he had allergies and that went away with taking claritin , but  i noticed that he gets the cough almost every  month . I worry so much coz he does not sleep well at night.
[|AI|]  Hello, Welcome to Chat Doctor, Your sons' history suggests me that he is having allergic bronchitis. He needs to test the blood sample for absolute eosinophil count to know the presence of allergy. The allergen causing the allergy should be identified by skin prick test and try to avoid that allergen. For the present condition I would suggest him to give1. Tab Least 10 mg once daily for 10 days.2.syrup Tusk DX. The symptoms will improve with these medications. Thank you.
