I am a 29 year old male suffering from Allergic rhinitis and Asthma. I got reverse spirometry test and chest x ray 2-3 months back. My FEV1/FVC was 81% and FEV1 was 71%. My chest x ray was normal. Two months ago, I developed severe breathing difficulty to which Doctor prescribed AbPhylline SR 200 for 1 month and Seroflo 250 for two months. I have already finished one month course of Abphylline Sr and about to complete two month course of Seroflo. But, now I feel slight breathing difficulty in the morning and in the afternoon. Should I continue with Seroflo for another 1 month or could you prescribe some other medicine? Now, I experience only a slight breathing difficulty.
