[|AI|]  Hello, Kindly, investigate with CBC and AEC count. If AEC counts more than 450, then fexofenadine plus montelukast combination Chat Doctor.  Otherwise, decongestant like Levocetirizine, OD or phenylephrine for five days can be prescribed. Steam inhalation can be done three times a day. Salt water gargle can also be done with warm water thrice a day. Hope I have answered your query. Let me know if I can assist you further.
