There are many options available to treat chronic rhinitis.  Your doctor may first take a medical management approach and prescribe medications, such as nasal antihistamines, nasal corticosteroids, or oral antihistamines to help alleviate your symptoms. There are also some home remedies like nasal irrigation that can help, as well as some over-the-counter nasal decongestant sprays.
Your doctor may also advise you to avoid triggers that cause your symptoms, such as wood-burning stoves and fireplaces, cleaning agents and household sprays, perfumes, and scented products. You may also be advised to quit smoking or not to be around people who smoke, especially if this is one of your triggers.
