PowerPoint review: levocetirizine (Xyzal), a third generation antihistamine
This presentation reviews some aspects of the third generation antihistamine Levocetirizine (Xyzal), the active enantiomer of cetirizine (second generation). What do you think? Is Levocetirizine worth it or not? Personally, I don’t see many advantages over other histamine blockers considering pricing factors.
