Steroid nasal sprays: While steroid nasal sprays may have some activity on reducing nasal inflammation as soon as 12 hours after a single dose, they don't achieve their maximum effect for several days. If you are having nasal congestion causing a sinus headache, you may need to take an oral or intranasal decongestant or antihistamine to get more temporary relief while the steroid spray takes effect.
