Hi, Your sense of smell can return after using Flonase, but it can vary from person to person. In most cases, loss of smell is a temporary side effect of using intranasal corticosteroids like Flonase. The good news is that most people regain their sense of smell once they stop using the medication. It is important to note that loss of smell can also be caused by other factors, such as a viral infection or nasal polyps. If your sense of smell does not return after a few days, it is recommended that you see a doctor for further evaluation. In the meantime, you may want to try using a saline nasal spray to help alleviate any nasal congestion and improve your sense of smell. You can also try smelling strong scents, such as essential oils or coffee beans, to stimulate your sense of smell. However, be cautious when smelling strong scents to avoid any potential irritants to your nasal passages. Take care. Hope I have answered your question. Let me know if I can assist you further.
