I am looking for an antihistamine for my 9 year old son who has multiple food allergies and environmental allergies.  I met with an allergist yesterday and he recommended xyzal syrup which is flavored.  i am not sure what the flavor is since he is allergic to a number of flavors including artificial flavors.would you know of what flavors are available?  the tablet form contains lactose and he is intolerant to dairy so not sure here as well.  please advise.
Rizal contains levocetirizine which is an effective antiallergic. Although a child could be allergic to many external principles, he would not be allergic to all. You may still give the medicine a try and see if he has any reactions to it. Chances are that he would not be allergic to them. As of now do not bother about the flavor. The amount of lactose contained in a tablet is not much and so it would probably not be a cause of concern. You may also try giving Montage LC Kid (montelukast + levocetirizine) in tablet or syrup form. I hope that helps. Feel free to revert with further queries if any.
