Dear doctors Post lockdown the packaged drinking water supplier in my are has closed his plant and the alternative water is causing immediate throat infection to me. I am addicted packaged drinking water since 30 years. Even boiled water is not helping me. By the same time of I drink like bisleri, kinley or aquafina even it is plain there will be no infection or any significant changes in my throat. And it is since 30 years going on. As of now I have mild throat infection . But no cough . Only phlegm in the morning as wakeup. Nose blockage .SHALL I TRY A COURSE OF AZITHROMYCINE or NOVAMAX 250. Please advice.
