How long can non-allergic rhinitis last?
Your question seems conflicting because Allergic Rhinitis is different from Non-Allergic Rhinitis. If it’s Allergic Rhinitis you’re having then it last for a lifetime and could even progress to Asthma. As long as you are exposed to the allergens your symptoms will appear. You have to consult for an Otorhinolaryngologist and/or an Allergologist to look more on your case. The medicines your taking are just for the symptomatic relief of your condition. If it is really allergic rhinitis, the best way to treat it is for you to identify the causative factors and avoid it. Remember that it can be treated but can’t be cured.
