I have seasonal allergies, I take Qnasl. But am still sneezing. Added on azelastine nasal, in which order should I use these meds?

Nasal sprays. These sprays have different mechanisms of action in treating allergic rhinitis and can be used once or twice a day without interactions. However I recommend spacing them out so that an interval of an hour or so transpires before using the other spray. Your pharmacist can be very helpful in instructing you on using these sprays.
