[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of recurrent viral URI (upper respiratory tract infection) is more. You are having pain in throat first and then cough, this clearly suggest URI. For avoidance of this recurrent episodes, I advise you to take Influenza vaccine annually. Influenza is the most common virus causing URI. So if you have taken vaccine against it, frequent episodes can be prevented. Protection is usually for 1 year and so it should be repeated annually. This will prevent frequent need of cough syrup and Chat Doctor.  Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
