My son has the normal allergies like pollen ragweed and dust, he now takes singular for it and he used to take zyrtek, so far so good with the sigular. I used to take allergra, but found it didn't work as well as zyrtek did for my allergies. I haven't tried singular, but I am sure it's helping my son because he's not nearly as congested as he was before starting on singular recently.
PS. Thanks for this new forum! Glad to be the first one to post a thread here. LOL!
Forgot to mention he has autism and seizure disorder along with his normal allergies.
