Before you go buying any products its worth doing some diags yourself. I have been to Specialist, docs etc and told them exactly the symptoms of my issues. Winter comes my face gets dry, dark circles around eyes, insomnia, etc.. The best is to diagnose yourself what the issues and why it happened. It appears Xergic worked all the times but the issue came back after in a week, found my place to be very dehydrated - used some tools to dehyrdate the room and place I live it, so far so good, Start of this Winter Season has not been bad and without any tablets. My issues are Definitely Not due to Hay-fever, and I have not used Xergic till now. Using some home based Dehydrator at my place. I will keep posted if there are further updates.

I have terribly itchy skin due to my psoriasis. I have been advised to take double doses of Claratyne, but after a few weeks it was not working at all. I then tried similar products with little improvement. I found Xergic 180 at a Discount Drug Store near me and decided to give it a go. I am really amazed at the result. I am not taking more than 1 tablet (sometimes 2) per day and my skin is not itchy anymore. My body may become resistant to it in time, but for now it is working very well.

I had skin welts for about 3 weeks in the evenings when it got a little hot
the welts itched and usually went away by the morning. (real bad welts)
After 1st tablet, that evening i had no more welts. 1 weeks now & i have not
had a welt. Also I sleep well & actually feel a little libido pickup.
Will stop taking them next week to see if the welts come back.
inexpensive. sleep well, no headaches etc.
so for no ill effects

I am an avid fan of trying the less expensive generic brands that are available. While I am not really comparing the different antihistamines that I have used, I did not have any problems or ill side effects when I took Xergic. The pharmacist clearly mentioned that this medication is non drowsy and I can't argue with that. I took them in the morning if I knew I was going to be outdoors later in the day, or right before leaving the house and I found that it was fast acting regardless of when I took it. My friends and family have also tried them and they reckon it is a great product.
Less expensive than other brands available. Non-drowsy.
