<human>: My son, 11 y/o, coughs hard in the middle night for about more than 3 weeks now. A pediatrician said my son has an allergy. She gave him a prescription of co-amoxiclav for 1 week and 5 tablets of cetirizine for 5 days. My son finished the prescribed medicine but he still coughs hard in the middle of the night. He doesnt have any known allergies before.
<bot>: Hello, You need to get him tested for allergies - without further deliberation as cough is a sign of hyperreactive airways' disease that can progress to asthma. Skin prick testing or specific IGE tests to aeroallergens will show what he is allergic to. Blood tests include: complete hologram (He TC DC ESR), IGE levels and lung function tests (pre-and post-bronchodilator) will be required. Long acting antihistamines and Alone nasal spray will help with the allergic cough; and bronchodilators such as Stalin or Step 2 Budesonide 200 2 puffs twice daily will be required if there is asthma on lung function tests. I hope that was useful. Best Wishes.
