I have been suffering from dry cough for last two months and a half. Accordingly taking the medicine montelucast+levocetrizine for last two months at night as per doctor prescription but with no improvement as such.It is pertinent to mention here that the episode of my mild to moderate dry cough generally begins in the evening and continues for maximum one hour.I do neither have any breathing problem nor any fever. Of late depending on further recommendation of my doctor I have undergone various medical test I.e., CBC, Chest Xray and serum IGE. Though the report of CBC and Xray report reveals normal but serum IGE level indicates 188.5. In view of the above, I seek valuable advice for my next course of treatment to get recovery from the cough as stated above. Saunak choudhuri
