- Try to identify and avoid any likely cause (allergens).
- Use newer non-sedating oral antihistamine drugs (e.g. Zyrtec).
- Avoid decongestant nose drops.
- Steroid nasal spray is very effective, especially in persistent allergic rhinitis.
Desensitisation is very effective if the allergic rhinitis is due to a single cause, e.g. grass pollen or house dust mite.
