Final answer:
Nondrug treatments for rhinitis due to allergens include avoiding exposure to allergens, using HEPA filters, nasal irrigation, hypoallergenic bedding, and immunotherapy for long-term relief.
Step-by-step explanation:
When treating rhinitis caused by allergens without the use of medication, several nondrug approaches may be effective. Avoidance of known allergens is the most direct non-pharmacological strategy. This can involve measures such as staying indoors when pollen counts are high, using air purifiers to reduce indoor allergens, or removing pets from the home if pet dander is the problem. Vacuuming regularly with a HEPA filter vacuum cleaner can also lessen exposure to allergens like dust mites.
Regular nasal irrigation with saline solutions is another nondrug treatment that can help clear nasal passages of allergens and reduce symptoms of rhinitis. Use of hypoallergenic bedding and pillow covers can create a barrier to allergens such as dust mites. Furthermore, wearing glasses or sunglasses outdoors can protect eyes from pollen, and taking a shower after being outside can wash pollen from skin and hair.
In addition to these measures, undergoing immunotherapy might provide long-term relief by gradually desensitizing the immune system to specific allergens. This requires careful testing to identify the responsible allergens followed by regular injections over a period of months to years.
