Hi, It sounds like you are already receiving treatment for your upper respiratory infection, including a course of Zpak (azithromycin), prednisone, Advair, nebulizer treatments, and promethazine for cough. However, if you are still experiencing persistent symptoms such as cough, wheezing, and colored mucus, you may need further evaluation and treatment. If you are feeling very tired and are still having difficulty breathing, it is important to seek medical attention as soon as possible. Urgent care or the emergency department may be appropriate options, especially if your symptoms are severe or worsening. At the medical facility, a healthcare provider will likely evaluate your symptoms, listen to your lungs, and possibly order additional tests, such as a chest X-ray or a sputum culture, to determine the cause of your persistent symptoms. Depending on the severity of your infection, you may be given intravenous (IV) antibiotics or steroids to help reduce inflammation and improve your breathing. In the meantime, it is important to continue taking your prescribed medications as directed and to rest as much as possible. Stay hydrated by drinking plenty of fluids, and avoid smoking or exposure to secondhand smoke and other irritants that can worsen respiratory symptoms. Overall, if you are experiencing persistent or worsening symptoms despite treatment, it is important to seek prompt medical attention to ensure proper management of your infection and prevent any potential complications. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
