Hi, Flonase (fluticasone) is a nasal steroid spray that is used to treat symptoms of allergic and non-allergic rhinitis, such as congestion, sneezing, and runny nose. It can also be used to treat certain nasal polyps. While it is generally safe for long-term use, it is important to talk to your doctor about any concerns you have about your medication regimen. If you are experiencing residual wheezing and shortness of breath after recovering from pneumonia, you may have developed asthma or bronchitis. These conditions can cause inflammation and narrowing of the airways, leading to wheezing and difficulty breathing. In some cases, inflammation from sinusitis can also contribute to respiratory symptoms. It is important to follow up with your doctor for a thorough evaluation of your respiratory symptoms. Depending on the underlying cause, your doctor may recommend continuing the use of Flonase and/or an inhaler, as well as other treatments such as antibiotics, bronchodilators, or corticosteroids. They may also recommend further testing, such as spirometry, chest X-ray, or CT scan, to help determine the cause of your symptoms. In summary, while Flonase can be used long-term for nasal symptoms, it is important to have a thorough evaluation by your doctor to determine the cause of your residual respiratory symptoms and determine the appropriate treatment plan. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
