Brief Answer: Levocetrizine should be taken. Detailed Answer: Dear Friend. Hi , I am Dr Anshul Varshney , I have read your query in detail , I understand your concern. I appreciate that you have already told that you have no fever , else i would have asked you!! It means you are aware. Good. Smog leads to reactive airway inflammation , which causes throat irritation. It's good you are doing gargles. I recommend 2 more things to do as follows: 1. Steam inhalation 4 times a day. 2. Anti Histaminics and Anti Allergic Drugs Like Levocetrizine 5 mg once a day for 3 days. You will get relieved in 3-5 days. Again avoid exposure to Smog. You may use a mask or handkerchief to avoid exposure when out in open. This is my personal opinion based on details available here. If you still have any query you may please ask me. Stay Healthy. Dr Anshul Varshney , MD
