I found this, too:
I have bad allergies too, jjh, and I also only have good luck with Allegra. Have you tried a neti pot? I think it's recommended to use it 2 or 3 times a day if you are having symptoms. I've not found it to be that helpful, but it does work a bit. The other thing that helps me is nettles! Nettle tea works really well. Nettle leaf capsules help a bit. As far as I know those would be totally safe during pregnancy because nettle is actually used as a food, so it should be fine in reasonable quantities. Otherwise these nettle capsules are my secret weapon: http://www.gaiaherbs.com/products/detail/52/Nettle-Leaf- It says not for use during pregnancy but that might just be a CYA thing? I think they are an extract of nettle though so I wouldn't take them without doing a bit of research first. I definitely find that they are almost as effective as actual antihistamines but without the yucky side effects. HTH!
A tablespoon of local honey with a teaspoon of cinnamon each day seems to help me. Also, my neti pot and a device called a sinugator (positive pressure saline wash) help with sinus symptoms when they flare up.
And if it's really bad and I can't sleep, I will break down and take a Benadryl.
MQ- I've ALWAYS heard about the honey thing and I'm super interested in the science behind it but last year I was in college and poor so I just stuck with my paid for Allegra. I shall try that too. Honestly I'm up for anything before a prescription!
Writeon- I hope my allergies aren't as bad this season as they normally are because of pregnancy but when I woke up sneezing this morning and itching I knew my luck may be thin! If the other things don't help I may have to break down for a nasal spray because I do feel better about that!
I had to quit my Allegra as well. I'm on my second course of allergy shots (first one was from ages 9-13 and lasted almost 10 years) and in maintenance, so I can continue them while pregnant (the serum doesn't cross placenta and I've never had a bad reaction). I had to switch back to Zyrtec (class B) which used to work really well for me after my first course of shots, but once they started wearing off, it was less and less effective.
I definitely think that the extra mucus, sniffling, etc., is making my morning sickness worse, and I think it's partly why it came back after it was almost gone for about a week and a half.
I also switched from Flonase to the Rhinocort Aqua, but since it's a brand-name, I pay a lot bigger copay than before. I hardly use it anymore because it just does not work as well for me and is too expensive.
