Yes, there are things you can do if you have lost your sense of smell due to COVID-19. One recommended treatment is nasal hygiene using a saline solution like Hydrasense or Sinus Rinse. This can help reduce congestion, which can contribute to loss of smell, as well as help with runny nose and cough. It is also important to stay hydrated by drinking plenty of fluids, whether they are cold or hot. If you have questions about your inhalers, it is best to consult with your pharmacist as they will have all the necessary information regarding your prescription.
