Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I can understand your painful situation as sometimes flu leads to simple dry cough disturbs all our routine life. As your complaints started only with dry cough and throat pain. Coming to medication, there are no specific medicines for viral infections. Viral infections have to be subsided by themselves by our body immunity (lymphocytes). That is why there is proverb that viral infections(flu) will get normal in 7 days without medicine and 1 week with medicine. But taking anti-viral medicine is the only option in case of flu, that is why your doctor would have prescribed. During the time of viral infections, our body immunity may get down and in such condition we may get bacterial infections (bronchitis). But main symptom in case of bacterial infection is fever. So check for any symptom of fever to know whether there is any bacterial infection. In my opinion, it is since 24 hours you got infection and no fever, so it may not be bacterial. Take rest for more time and plenty of water. Your symptoms will subside soon. Hope I have answered your query. Let me know if I can assist you further.
