Hay Fever – Nasal Sprays
Nasal symptoms of hayfever, such as a blocked or runny nose, can be treated directly with a nasal spray for fast, targeted relief
About hay fever – nasal sprays
Corticosteroid nasal sprays (intranasal corticosteroids, or INCS) reduce inflammation directly in the nasal lining, targeting the swelling that causes blockage, congestion and mucus production. They're considered one of the most effective hayfever treatments for nasal symptoms and work best when used regularly rather than only when symptoms flare
Treatments
Symptoms
• Blocked or congested nose
• Runny nose with clear discharge
• Sneezing
• Post-nasal drip
• Reduced sense of smell
• Nasal itching
Diagnosis
Nasal hayfever symptoms are usually diagnosed from their seasonal pattern and typical presentation. Persistent one-sided symptoms, nosebleeds, facial pain or symptoms outside pollen season may need further assessment for another cause
Treatment
Corticosteroid nasal sprays are used once or twice daily and take a few days of regular use to reach full effect, so starting before symptoms peak improves control. Saline nasal sprays or rinses can help clear allergens and mucus, and decongestant sprays may offer short-term relief but shouldn't be used for more than a few days
Prevention and self-care
• Start using a nasal spray before the pollen season begins if hayfever is predictable
• Use the spray correctly, aiming slightly away from the central nasal septum
• Use it daily during pollen season for best effect, rather than only when symptomatic
• Keep windows closed and avoid outdoor activity during high pollen counts
• Rinse the nose with saline after high exposure
• Wash bedding regularly during pollen season
