RCT
In June 2021, the FDA approved Astepro Allergy (azelastine HCl 205.5 mcg per spray) as the first over-the-counter antihistamine nasal spray Expert In a placebo-controlled trial of azelastine nasal spray 0.15%, onset of symptom relief was reported within 30 minutes of dosing (Shah 2009) Expert Dymista is an FDA-approved fixed-dose combination nasal spray containing azelastine HCl 137 mcg and fluticasone propionate 50 mcg per spray, indicated for seasonal allergic rhinitis in patients 6 and older Expert In a Phase III RCT (Carr 2012), the azelastine + fluticasone combination spray (MP29-02 / Dymista) produced significantly greater nasal-symptom relief than either agent alone or placebo in patients with moderate-to-severe seasonal allergic rhinitis Expert Combining azelastine and fluticasone propionate (whether co-administered or as the co-formulated product Dymista / MP29-02) produces greater allergic-rhinitis symptom relief than either agent alone, demonstrated in three Phase III RCTs in moderate-to-severe seasonal allergic rhinitis (n=3,398) Expert Dymista’s cash price typically ranges from about $50 to $260 per month depending on the pharmacy, and is often substantially lower with insurance coverage or a GoodRx coupon Expert

Which should you pick?

For mild-moderate itchy nose and sneezing without much congestion, standalone Astepro is sufficient and OTC. For moderate-severe AR (particularly with nasal congestion as a dominant symptom), adding the fluticasone component matters; Dymista provides both actives in one bottle via Rx. If an Rx is inconvenient, the OTC stack of Astepro + Flonase is pharmacologically equivalent (see the Flonase vs Astepro discussion for the stacking rationale).

The mirror comparison (Flonase, the steroid alone, versus Dymista, the combo) is covered on the Flonase vs Dymista page.

Winner in context: Allermi is our #1 for eligible adults

If you are weighing Astepro against Dymista, you are already in combination-therapy territory. For eligible patients 13+, Allermi is our overall pick: the same steroid + antihistamine pair Dymista proves in RCT, plus ipratropium and micro-dosed oxymetazoline, personalized to your intake.
