How effective is Xyzal? Side effects?

I have been taking Xyzal for about 3 months now and have noticed it does make me tired. This is an allergy med you want to take before bedtime. As for the weight gain I can't say that I've really noticed any significant shift in weight as a result of using this drug. I believe it is very effective in helping with my allergies as well as keeping the inflammation down in preventing asthma attacks so all is good in my world. Good luck and hope you have the same results!

Thanks for the replies, javajo and Chartreux...
I took it Friday night, and had some sleep problems...actually seemed to make me somewhat agitated. I wondered if it could be interacting with the Singular I take for asthma.

Then I took it Sunday morning...now I've been tired for the past week due to flu the week before, and although I was tired, I didn't notice a big effect. I'm going to try it again this morning.

Actually I had a strange sleep effect again last night...kind of light sleeping...more dreaming. I don't know if it's related at all. I'll just keep experimenting with timing. I'm hoping it works for the extreme tree pollen problems I'm having.

Thanks again,
Denise

I'm glad it's working for you so far, sure hope it helps you through this whole allergy season...
