No I know that my allergies is to cats. I was allergy tested a few years back so I know it is. It also only comes up as a result of being in direct contact with cats or dogs so I know it is nothing else. In other words I always have a reaction every time I visit my sister.

I'm also allergic to dust which ALWAYS brings up hives. I again was put on real harsh drugs as I was developing hives daily and had to go through an elimination process. Loratadine doesn't help me at all, and neither does any of the other meds I have been on. The med I'm taking now on a daily basis is Phenergan, I have taken it every day since june but use it for nausea and vomiting (for my illness) and it doesn't help my allergies although it's an allergy med.
