For a long time I'm suffering from allergy. Well it is hard to be cured. So one tried homeopathy, others sedative drugs, diets and so on. Well, as for me I'm trying not to eat my no list products, but what can I do with dust or other things, for example cold. I tried a lot of anti-allergic pills, and stopped on CETRIZIN HEXAL, yes it has great sedative effect than other products from third generation but It really helps!
