What is an equally effective over-the-counter alternative to the nasal spray astepro used for chronic sinus infections cost is a factor.?

Unfortunately there. Is nothing cheaper that may be as effective as Astepro intranasally speaking. There are several pills by mouth that may help but not be as effective if it has worked good for you.
Astepro. Hello, Astepro is a topical antihistamine. An otc alternative would be claritin, zyrtec or allegra. These are pills to take by mouth and not a spray. Currently, there are no topical antihistamine nasal sprays otc. Astelin is a antihistamine topical nasal spray that is a generic and thus cheaper. You need a rx from you doctor for this medication.
