15 month old w/severe seasonal allergies?

[mrseum]

Is there anything OTC that's safe for a lo this young?? I plan on asking the pharmacist today- but wonder if you mamas had any ideas. He has for allergies too-but there is a big correlation between high pollen days & this. He's sneeze so many times this morning his eyes are swollen & he is just miserable. :/ unfortunately the allergist couldn't get us in until October. He can't even breathe/sleep well at night with the aid of a humidifier, Vicks plugin AND benedryl with decongestant.
