<s>[INST] Can hay fever make my asthma worse? [/INST] 
Yes. An itchy, runny or blocked nose due to hay fever or allergies (called allergic rhinitis) can make asthma harder to control. The good news is that treating the symptoms in your nose and throat can also improve your asthma symptoms.

Corticosteroid nasal sprays are effective treatments for managing allergic rhinitis. They can be used every day long term, if needed, just like preventers for asthma.
