Ahhhhh....a subject near & dear to my heart......
I have had continuous allergies for over 5 plus years now...have been getting allergy shots for over 5 years now........another 3 plus years of shots....but here is what I have found that helps me....... (I am allergic to everything, except cattle and cockroaches)...... grass, pollen, trees, hay, cats, dogs, horses, mold, dust, dander.....(you get the picture).
Anyhoooooo....besides the shots.... I take Allerclear daily (one a day pill...it is Costco's version of Claritin)...same ingredients & is non-drowsy....for those that take meds regularly you know how important the non-drowsy stuff is. Much cheaper than Claritin and it was my allergist that recommended I switch since it's the same thing (I took Claritin for a few years before the switch). I also take a generic version of Flonase (I personally like Nasonex better)..but my current health insurance does not cover Nasonex......so Flonase nasal spray, my generic version is the best I can get right now...and it does help, just not as well as Nasonex. Another secret from the allergy people.....Pepcid AC....yes the acid controller.....and it can be the generic version as well..(again I buy mine at Costco, saves me $)...also helps with allergies....I take the Pepcid stuff each time about an hour to hour 1/2 before I get my allergy shots...(so about once a month now).....plus if I am having an esp bad time with allergies on a given day, I will pop a few of the Pepcid pills....
I also take singulair every evening .......so I have asthma & allergies....but the Singulair helps with both....plus I have an inhaler, which I have had to use more frequently lately.....so much blooming right now. I also would say if you are going out to do yard work, etc....get a mask to wear.....and like MA said, if you change out of your clothes that may help you as well.
NeilMed makes a great nasal rinse that can help with seasonal allergies too....and it comes as a kit, very easy to use....I find easier than a Neti-pot.....comes with a saline solution and you just mix it up & squirt up your nose, etc......tends to rinse all the irritants out of your nasal passage etc.
Sorry this is so long, but gosh, if this info can help anyone, I am happy to share.
That said, even with all of the above, I do have some "bad" days where nothing works as well......and I have indoor cats so I am constantly barraged with allergens, but I am not about to give up my cats because of allergies.......but they do know on "shots" day, they can't snuggle with me.
Take care and I hope you find a way to get through your allergy season...unfortunately for me, my allergy seasons last all year long.......the only relief I get is when I go on vacation to somewhere tropical......Hawaii is my cure for my allergies....
